E M B A N K M E NT A S IT C O U L D B E A NEW INTERFACE WITH THE RIVER THAMES London, United Kingdom
S
ituated on the Embankment along the Thames (London, United Kingdom), ‘Embankment As It Could Be’, responds to the current urban interface with the River Thames bank and seeks to offer a new public space, unknown to London thus far. The challeng-es posed by the River Thames, make the interface challenging with the tides frequent-ly changing. The site is amongst the most well-known locations in the capital, with Westminster, London Eye & Trafalgar Square all in close proximity, however the site is currently occupied by noise and air pollution from the vehicle traffic that currently runs along the Embankment. The river edge provides great social potentials in cen-tral locations within the city and in continuation of the spirit of Embankment’s creator Bazalgette and other proposals such as ‘London As It Could Be’ by Richard Rogers, the new scheme aims to propose a new social interface along the Embankment and engage with retaining the existing wall and opening up the wall onto the river edge when the tide is low. To act upon the challenges of the River Thames, the project excavates the Embank-ment and retains the existing wall with a concrete case and steel retaining structure. In response to the changing environments, the kinetic nature is embedded in the building with hydraulic cover hatches positioned on the roof and the wall, in order to open and close the building depending on var ying environmental and program conditions.

IRON IN EARTHS CRUST
MOST COMMON IRON-BEARING MINERALS
The mass of the Earth is approximately 5.98×1024 kg. In bulk, by mass, it is composed mostly of iron (32.1%), oxygen (30.1%). In the early stage of earth’s creation, the heaviest material like iron sank to the core. Lighter material remained on top to form a crust.
The most commonly used iron alloys are Hematite and Magnetite due to their iron content of approx. 70%.

CAST IRON, WROUGHT IRON, STEEL CARBON CONTENT: Steel has a varied carbon content, based on how long it is heated will determine the carbon content. It has great formability and durability, good tensile and yield strength.
Wrought iron has a very low carbon content making it soft and gives it the ability to bend.

EARLY RESEARCH IRON PROPERTIES The properties of iron as a building material can change drastically depending on the metallurgy process it undergoes. The tensility of the product largely depends on the carbon content and with less carbon content the more tensile it will become. Wrought iron, cast iron and steel all contain very different properties.

BLAST FURNACE 6TH C. BC First used by the Chinese in 6th c. BC, but more widely used in Europe during the Middle Ages. Melting iron at very high temperatures, resulting in cast iron (2.5-4.5% carbon).
TOOLS
PUDDLING FURNACE 1784 Developed by Henry Cort in 1784. Transformed cast pig iron into a low-carbon content wrought iron. Stirring the molten iron with oxygen slowly removed carbon.
IRON BRIDGE 1779
BESSEMER PROCESS 1856 Iron heated in the Bessemer Converter whilst oxygen was blown through the molten metal enabled the production of a more pure iron. The draw back was that too much carbon was removed and too much oxygen in final product.
CRYSTAL PALACE 1851
OPEN HEARTH PROCESS 1860s German engineer Karl Wilhelm Siemens produced steel from pig iron in large shallow furnaces, increasingsteel production. The heated brick chamber below the hearth enabled burning off excess carbon & other impurities.
BROOKLYN BRIDGE 1883
FLUX 1876 Welshman Sidney Gilcrhist Thomas found that adding a chemically basic flux, limestone, to the Bessemer process would draw out phosphorus from the pig iron into slag.
1ST STEEL FRAME SKYSCRAPER 1885
ELECTRIC ARC FURNACE 1879 Designed to pass electric current through charged material resulting in exothermic oxidation and temperatures up to 1800 °C. EAFs produce steel from 100% scrap and now account for 33% of global steel production.
EIFFEL TOWER 1889
OXYGEN STEEL MAKING 1960 66% of global steel production is now produced by basic oxygen facilities. The basic oxygen furnace blows oxygen into large quantities of molten iron & scrap steel and can complete a charge much faster than open hearth methods.

01. FOUNDATIONS
Trenches were dug; then the concrete foundation with basket foundations to fit the iron columns into were placed.
02. ERECTING COLUMNS
Workmen began erecting columns and were raising around 200 columns a week. At the same time, girders were added to support the galleries and the roof.
03. PLACING TRANSEPT ROOF
One of the most difficult parts of the construction was hoisting the main ribs for the transpet roof. All 16 ribs were fixed in one week. The roof was made of laminated timber and was hoisted up soley using human power.
04. ROOF FOR MAIN BUILDING
The roof for the main part of the building was added. Glazing wagons ran in grooves in the gutters. In one week 80 men put in over 18,000 panes of glass.
05. DECORATIVE FACADE
Finally the exterior iron frames and windows were added.
EARLY RESEARCH CRYSTAL PALACE CONSTRUCTION PROCESS The Systemic approach used to build the Crystal Place meant that it was built at high speed using solely workmen other than when erecting the roof trusses, where horse power was used. The construction diagram shows the simple logic and steps in the process of constructing the building.

FOLDING METHODS
STEEL FABRICATION
STEEL GRAIN RESULT WHEN FOLDED
Advanced steel fabrication for folded sheet steel structures consists of precise fabrication techniques using specific equipment and knowledge of how the material works.
Steel must be folded with the grain to avoid cracking.
FOLDING: It is imperative to bend with the grain of the steel otherwise you will crack the steel. The folding can also weaken the sheet steel so should be careful where and when needed to do so and at appropriate angles. WELDING: Welding uses extreme temperature to melt steel so that when it cools it creates a chemical bounding. Mig welding requires careful technique as it deforms the metal.

WELDING
Mig welding is used for welding the sheet steel into components of site. The heat generated through the electrodes heats the steel to melting point so that when it cools the steel joins together. Deformation can occur so blending is carried out afterwards to smooth the welding on the surfaces.

TRACING PROPOSALS ON THE VICTORIA EMBANKMENT
BRINING VILLERS ST. BACK TO THE RIVER EDGE Before the Embankment was constructed on the River Thames the river edge lay infront of Villers Street, which is now marked by a watergate monument. The reclaimed land within close proximity to the chosen site is occupied by Victoria Gardens, Embankment underground station, road and footpaths.
Since 1666 proposals have been made on an Embankment on the River Thames. After numerous proposals the Embankment was finally realised by Joseph Bazalgette. More recently the Embankment has been speculated on by pedestrianising the site and enriching the public interface with the river edge.

2025 “London As It Could Be” As a result of the mass redevelopment in London, Rogers felt great opportunities to improve the capital were being ignored in favour of a piecemeal approach to planning. Rogers proposed, in the spirit of the Embankment’s creator, Bazalgette, that the road along the embankment be sunk in a tunnel, allowing the river-side to become a new linear park.
1874
Victoria Embankment
Super Sewer The current sewer by Bazalgette is outdated and the new London super sewer will be built and completed by 2024.
1986
The first person to suggest a river embankment was Sir Christopher Wren after the fire of London in 1666. Work eventually began in 1864, depsite opposition from commerical interests, notably the wharfingers. It was carried out under the control of the Metropolitna Board of Works’ chief engineer, Sir Joseph Bazalgette (1819-1891). The Embankment was not just to ease traffic congestion and beautify the river, but to house the main sewer. This stopped the other sewers flowing directly into the Thames.
Northumberland Avenue Northumberland Avenue was built as the main approach road to the new embankment. It necessitated the demolition of Northumberland House.
1871
Sir Christopher Wren As a result of the fire of London in 1666, Sir Christopher Wren proposed a new plan for central London which included an Embankment along the River Thames. This proposal was never realised.
John Martin In 1824, solder and aid to George IV, Sir Frederick Trench proposed ‘Trenchs Terrace’, which would create an embankment from Blackfriars to Charing Cross. Trench brought a bill to Parliament, however it was blocked due to river interests.

The Great Stink The smell of untreated human waste and industrial effluent that was present on the banks of the River Thames. The problem had been mounting for some years, with an ageing and inadequate sewer system that emptied directly into the Thames. During 1858 a bill was passed in Parliament to begin works on Embankment, which would also involve the construction of a modern sewer system that would take the waste out of London.
Sir Frederick Trench In 1824, solder and aid to George IV, Sir Frederick Trench proposed ‘Trenchs Terrace’, which would create an embankment from Blackfriars to Charing Cross. Trench brought a bill to Parliament, however it was blocked due to river interests.

SITE LOCATION: VICTORIA EMBANKMENT, LONDON, UK WESTMINSTER BOROUGH (CAZ ZONE)
Victoria Embankment is located in a central nodal part of London, the capital city of the United Kingdom. Victoria Embankment neighbours the River Thames, an iconic river that has lots of history associated with it, which makes London for what it is.The challenges of the river edge are a key driver for the site selection.
LONDON
HISTORIC SITE Victoria Embankment is a relatively new space in London, since 1871 when Joseph Bazalgette led the construction which reclaimed 36.5 acres of the River Thames to provide a sewer in response to the poor sewage network and hygeine in London.

TUBE TRANSPORT
BARS & RESTAURANTS
STATUES
A series of gardens are located in the Embankment area with a wide range of flowers and trees.
The tube line is connected to Bakerloo, Northern, District & Circle tube lines.
Bars and restaurants surround the back streets of Embankment and some quiet restaurants are located in boats.
Embankment has a rich history, thus multiple statues are located along the pathways and in the gardens.
PUBLIC FOOTPATH
FERRY TRANSPORT
FOOTBRIDGE
CENTRAL NODAL POINT
There is a wide public footpath located along the river edge, offering great views of London.
Embankment pier is a stop for 5 Thames Clipper routes, as well as offering rib experience at the Embankment pier.
The hungerford footbridge connects pedestrians between Embankment and the Southbank.
Located in a central nodal point in London, which is well connected to multiple highly integrated and active areas.
SITE & BRIEF SITE CONTEXT An exploration into the sites context. The site has a significant historic context, which is marked by a number of monuments such as the watergate monument that marks the original river edge of the River Thames. The site is also a key interchange for river and tube transport . In the section the tube lines are located to avoid disrupting these flows in the construction of the performance arena and wine bar.

SITE & BRIEF SITE CIRCULATION Circulation and the flows the surround the scheme are important to be aware of. The transport interchange between the tube transport infrastructure and river transport infrastructure are keys flows for getting people to the site. The pedestrianisation also creates a better public interface with the Embankment and a more suitable street circulation option..
35
SITE HISTORY
The site is was originally developed between 1865 - 1871. The urgency for London to deal with its waste issues was a catalyst for the original scheme, enabling the construction of a sewer beneath the Embankment. The Embankment continuously developed over coming years with a road to connect the city.
CURRENT SITE CONTEXT
The site currently has a road with high volumes of traffic causing high pollution and noise. This has a severe impact on the circulation of the city and with forecasted urban growth new visions of how the city circulations its high traffic volume must be dealt with. This project aims to pedestrianise the main street by 2035 for the projects due date and instead rely on e-cargo bike and river transport for the circulation of freight.
SOCIAL IMPACT The social impact through pedestrianising Embankment will deliver multiple social benefits and enhance public interface with central nodal locations on the city. The performance arena and wine bar begins a proposed developement to outline the future aims of making London a greener city and reducing traffic and its negative impact.
BENEFITS & METRICS
TRAFFIC & CONGESTION Nearly 70% of worlds population will be living in cities by 2030. This doesn’t bode well with the UK being ranked as 3rd most congested country in Europe. The average Londoner spends 100 hours every year in traffic.
PUBLIC HEALTH Obesitiy is a growing problem and more than 40% of Londoners do not achieve the recommended 150 mins of activity a week. The air pollution caused by vehicles has also proven to contribrute to deaths.
SAFETY Almost 1/3 of Londoners do no tfeel safe in the captial and road traffic injuries are the leading cause of death among people aged between 15-29 years.
PROFIT Walking and other non motorised transport typuically increase retail sales by 30% and Londoners have declared they would increase council tax to pay for pedestrian environments.
HAPPINESS & WELLBEING London has been declared the least happy major city in the UK. By improving walkable environments it can reduce mental health probelsm and improve the wellbeing of commuters.
CURRENT CONDITION The current coondition of the Embankment has a negative impact on the city, with high volumes of traffic and weak public interface in a central routewhich offers great public benefits.
ATTRACTIVENESS 35% of Londoners state the capitals history is their favourite part about living in the city. The new North Terrace of Trafalgar Square had a 300% increase in visitors after pedestrianising.
SITE & BRIEF PEDESTRIANISATION The project proposes that the Embankment is pedestrianised for a wide range of urban social, politcal and economic benefits.

CULTURAL SCENE LONDON
THE LONDON PLAN
The site is located in an area identified as a Core CAZ area. It is an economic powerhouse and international destination, home to global companies, world‐class hotels, 40 theatres, 20 cinemas, 30 museums and, galleries, about 2,500 restaurants, public houses and bars and over 2,000 shops, all showcasing the best London has to offer in terms of retail, culture, leisure and entertainment.
The Mayor of London amplified his vision to rescue the declining cultural scene in London, in his 2015 campaign. It is a growing concern that Londons cultural opportunities for the public are disappearing.
Creative Industries are an important element to the Westminster economy and interdependent with a vibrant cultural sector. The West End, particularly Soho, has the highest concentration of creative businesses in the world. The central part of Westminster has one of the largest clusters of cultural and entertainment uses in the country centred around the West End, including Theatreland, Trafalgar Square and Somerset House.
The new London plan, published at the end of 2017, focuses on Londons growth for the next 20-25 years and highlights Londons heritage and culture, which proposes a specific culture plan for London.
STRATEGIC CULTURAL LOCATION This has been designated a Strategic Cultural Area. Millbank, along the Thames Riverside, is also a Strategic Cultural Area, including Tate Britain and the Chelsea College of Art and Design.
RESCUE PLAN FOR LONDONS MUSIC VENUES The success of Londons music industry depends on flourishing grassroots music venues. These are the places where stars make their names. Londons grassroots venues have always been the places to find new talent. Every night nearly 14,000 people go to a gig in a grassroots music venue in London, but a fifth of Londons grassroots venues could be forced to close due to business rates increases.
CULTURAL VENUES ON THE DECLINE London has has lost 185 nightclubs and live music venues since 2007 - a decline of almost a third. The map below shows the closure of night club and live music venues through the years.

HYDRAULIC COVERS
PERFORMANCE ARENA A performance arena for providing cultural infrastructure in a central nodal location, where the increasing urban density has recuced opportunties for cultural venues.
06
Creating a natural stepping from the street level into the arena onto the artifical landscape will provide natural flows for the public to interact with a social space and the river edge.

WINE BAR Relocating Gordons wine bar on the river edge provides a new social experience for the public to enjoy in conjunction with afternoon/evening events.
RIVER TAXI SERVICES The ferry infrastructure offers water taxis that give direct access to the Embankment underground station, as well as providing access straight onto the landscape to enter the performance arena & wine bar.
Creating an artificial landscape on the river edge provides an outdoor public space close to the river, providing a new social experience and interface with the River Thames.
11
TIDAL ANALYSIS The constant change in the tidal level creates a challenging environment to connect the land and river space for public activity.
09
LANDSCAPE
PEDESTRAINISATION Pedestrianising the Embankment enables better public interface with central streets where high levels of pedestrians currently occupy. It will also reduce noise pollution & air pollution.
The Embankment reclaimed 37 acres of the River Thames and the original edge lays infront of Gordons Wine Bar. Brining the wine bar back to the river edge will reimagine the historic river edge conditions.
Embankment provides a key interchange between the river transport infrastructure and tube transport infrastructure.

CHANGING ENVIRONMENTS The flow from the street level into the new space varies constantly based on environmental changes. The new urban spaces offers three different social zones as the public flow through. These consist of the park, the arena and the landscape. The tide changes the opening and closing of spaces.
SITE & BRIEF STEPPING DOWN TO THE RIVER EGDE At certain points in the day the tide is low enough for the hydraulic openings to open out and create a bridge out onto the artifical landscape that sits on the River Thames. The times change slightly every day, but change a lot over the course of a month so its important to use the tide predictor, which is highly accurate to know when the arena opens out onto the River Thames.

OPENING/CLOSING HATCH When the tide level is close to going above the opening, the hatch is retracted with hydraulic pistons. The hydraulic pistons will also open the hatch when the tide falls below the opening.
Median low water level reaches approx 1.0m
Fully extended cover hatch, opening the opening within the existing wall
LOW TIDE When the tide is low, the hatch can be fully extended to allow the general public out onto the artifical landscape, which sits on the river edge. It also allows natural ventilation and sunlight into the arena.
SITE & BRIEF HYDRAULIC WALL OPENINGS There are three hydraulic hatch covers that open and close out onto the River Thames based on the tidal level. When the tide level is below the opening the cover opens out using hydraulic pistons. The hatch cover uses the same logic as ship cover hatches and follows the watertight properties of the ship cover hatch.

DESIGN DEVELOPMENT STRUCTURAL LAYERS The structural layers begin with a concrete secant pile wall casing with watertight concrete as a base. To retain the hydrostatic pressure and integrate key services for the building, a sheet steel structural system made up of folded sheet steel and stiffners. On top of the stiffners is a sheet steel roofing system that connects openings such as they hydraulic openings.

STAGE 1: COFFERDAM
The first operation is to construct a cofferdam the width of the concrete landscape and then remove the water within.
STAGE 2: LAY LANDSCAPE
A concrete landscape is then built and the two entrances are excavated for ease of access to the main excavated area later on, such as scaffolding.

STAGE 3: SECANT PILE WALLS
Secant pile walls are inserted with a concrete case as the first layer of retaining the wall.
Pedestrian flow maintained
(A) Secant pile walls are installed and then site excavated. Steel retaining roof will then be inserted to complete the retaining structural system.
Pedestrian flow maintained Operation highlighted River Thames (transport route for waste and equipment)
(B) Landscape used for storing equipment and machines in construction. Cofferdam will stop water entering site during this proccess and will stay in place until all works are complete.
DESIGN DEVELOPMENT CONSTRUCTION STRATEGY The construction strategy works with the complications of building on a river edge. To combat the challenges this brings, a cofferdam is constructed to avoid the hydrostatic pressures against the wall whilst it is excavated and retained. Once the concrete landscape is erected, it will be used for storing equipment and machinery. The materials and waste are transported via the River Thames.

CONSTRUCTION STRATEGY OF RETAINING STRUCTURE
01
Delivered by barge by river
02
Passed to crane on land
The strategy focuses on being as time efficient as possible, thus the structures are split into several modules offsite and inserted straight from the barge into the excavated site. The methods of connecting elements to the secant pile wall and concrete case is both welding and bolting. Once the secant pile wall is inserted and the site excavated a waterproof concrete base is poured to lay the foundation. Core cutting machines are then used to cut holes in the walls for the openings. After the concrete phase is complete, the steel structure needs to be installed. Firstly, the lower ground steel modules are inserted followed by the ceiling to roof modules which are the primary retaining system. Once the steel structure is fully installed the cofferdam can be removed as the wall will be fully retained, thus the hydrostatic pressure is no longer a concern.

KEY CONNECTIONS
SECTION CUT
Connecting the various elements focuses on high integration of the various elements and follows a similair logic to the structural organisation of a semi-monocoque structure.
The section cut explains in detail how the acoustic panels are fitted within the steel structure and the systems that circulate the steel structure to aid the performance arena experience. The panels are fitted in with steel caps that are welded to the steel structure.
ACOUSTIC ROOF CONNECTION
KEY
The sheet steel retaining roof structure creates openings to allow the insersion of timber acoustic panels to enhance the acoustic conditions of the performance arena. Artificia lighting is also fitted around the edge of the openings to integrate lighting into the performance arena. The exploded isometric diagram below shows the layers of the structural retaining roof modules which are constructed off site. The structural layers connect steel elements through mig welding, whilst the timber acoustic panels are simply slotted in.

SEMI-MONOCOQUE STRUCTURAL SYSTEMS (CASE STUDY: SPITFIRE)
04
Interogating the structural systems that construct the spitfire open up opprtuntieis also relevant in architecural structural systems. The spitfire wing is made up of ribs (stiffners) which allow for the planes operating systems to run through. The wing is then wrapped in an aluminion skin. This system makes a high efficient structure and amalgomation of integrated systems, postition strategically to carry out its role.
03
01 02
The same logic is used in the retaining structure for the performance arena and wine bar. Whilst also acting as a retaining structure and roof it also integrates an amalgomation of systems such as air ventilation, sound, and lighting.
DESIGN DEVELOPMENT KEY CONNECTIONS The structural logic follows the same logic of the spitfire semi-monocoque structure. Sheet steel structures are used for the ceiling and roof and sandwiched between the sheet steel structures are timber acoustic panels and stiffners.

HYDRAULIC OPENINGS
WATERTIGHT
SHIP COVER HATCH DETAIL
The hydraulic openings mimic the same logic of the ship cover hatches, however with only one cover and extending from 90 degrees to 0 degrees. This allows for the cover to open up and create a bridge to allow the public to move out onto the landscape that sits on the River Thames. When the tide is at the height of the platform, the platforms retract.
The ship cover hatches are proven to be watertight and withstanding huge water loads from waves crashing on top of the ships. It is vital they remain watertight to protect cargo. The same security is necessary for keeping the basement arena watertight from the River Thames hydrostatic pressures.
The ship cover hatch design and logic is applied to the wall opening as a proven system used to create an opening that is water tight especially under extreme water load when waves crash onto the roof.

The folded sheet steel construction system allows for the concealment of intergral services within the structure. This allows functions of the building to be activated directly through the network of beams and columns.
One method of passing services through different levels is through beams. This beam fragment sutdy shows how the beam which is made up of steel sheet and stiffners can pass services through horizontally as well as vertically.

DESIGN DEVELOPMENT INTEGRATED STRUCTURAL SYSTEM As well as providing a structure that retains the hydrostatic pressures against the wall, the structural system also carries the services throughout the building. The wide network of beams allow for different services to feed through different zones of the building. For example there is a greater emphasis on sound systems on the more central beams and a greater emphasis on water services on the outer beams.

INTEGRATED SEATING
WINDOW OPENING
MAIN HYDRAULIC ROOF
On the roof, which connects with the pedestrianised street, the sheet steel lifts up to create seating for the general public. Through folding sheet steel it offers a multitude of structural opportunities, whilst also inventing social opportunties.
A window opening on the roof allows for the general public to look into the perfomance arena, whilst also allowing constant natural light in, without impacting the thermal performance of the arena space.
The main hydraulic roof has one large cover hatch, with 6 smaller sliding cover hatches. The large opening has multiple mirrors attached to reflect the environment and is opened and closed using hydraulic pistons. The smaller sliding cover hatches are also opened and closed with hydraulic pistons, however with sliding mechanims (wheels) to open and close the covers.

VIEW FROM MAIN ENTRANCE The view from entering the entrance via the park. When all of the hydraulic openings are open the openings provide lots of light, as well as framing the surrounding site context.
VIEW OF APPROACH TO OPENING On approach to the side wall opening with the steel structural system guiding and providing artifical lighting to the arena. The steel structure is infilled with timber panels for better acoustic performance.
VIEW ENTERING ARENA FROM RIVER Entering the arena from the landscapewhich is well lit with the integrated artificial lighting. Sun light also enters from a side hydraulic openings during daylight hours which adds to the overall atmosphere.
VIEW OUT OF MAIN HYDRAULIC ROOF The main hydraulic roof lays above the centre of the performance arena and its size opens up grand views of the London sky. The mirros on the hydraulic opening also reflect the site context from below and the activity of the arena from above.
APPENDICES ARENA TESTS

HYDRAULIC SYSTEMS Much of the performance strategy focuses on the roof system. The roof shell uses hydraulic pistons to open and close areas of the roof to create kinetic opportunties. The key aims for the roof to achieve are:
KINETIC ROOF OVERVIEW
01. Reflecting environments in mirrors under roof surface 02. Allowing passersby to see into spaces and for people within to see out 03. Enable natural ventilation 04. Allow natural light into the spaces 05. Open up the arena to the river edge
Ship cover hatch using hydraulic pistons
Hydraulic piston
VISUAL CONNECTIONS The openings enable visual connections directly in or via the reflective surfaces that reflect the site context. SOLAR LIGHT The building is south facing this the roofs are positioned to open up and allow the solar light into the building. INTERACTIVE ELEMENTS The roofs become interactive with the public, such as providing seating, projected screens etc.

NATURAL LIGHT Opening up the hydraulic roofs will allow natural light into the arenas, which can enhance the atmosphere of a particular time of day or performance.
AIR FLOW Allowing natural air to flow in and out of the building is key to regulate a comfortable temperature within the arena, which will have large bodily heat produced.
REFLECTIVE The hydraulic roofs have mirrors which reflect the activity within and the surounding context of the site, which is largely to be sky scrapers and trees, as well as the public engaging with the surrounding spaces.
REFLECTIVE As an underground venue, particularly staff who will be working for a long period of time, exposing the building to outside is important for wellbeing.

LIGHTING STRATEGY Due to the building proposal being a basement project it is important to clarify the lighting conditions. The hydraulic openings will play a key role in the light conditions during the day as well as influencing the atmosphere throughout th enight. Following are four key considerations which impact the lighting condition
01 CLIMATE CONDITION Whether its raining or clear skies will depend on whether the hydraulic roofs can open for light.
03 EVENT TYPOLOGY The artificial light system is key in providing a lively atmosphere for specific events.
02 AMOUNT OF SUNLIGHT Amount of light changes all year round, thus impacting level of natural light available.
04 WELL-BEING Accessing natural light can be stimulating for the wellbeing of users when possible.
NATURAL LIGHT: 50,000 - 100,000 LUX ARTIFICAL LIGHT: 50 - 1,000 LUX
(Lux is the level of light that falls on a surface)
NATURAL LIGHTING Earlier during the day when the light from the south west enters the building through the roof openings to light up the interior spaces.
09.00AM JUNE 01 2020
NATURAL LIGHTING In the evening the natural light creates limitted inteior light other than along the central axis.
18.00PM JUNE 01 2020
ARTIFICIAL LIGHTING A study describing how artifical lighting can impact the interior space. The artifical lighting is also important in lighting the spaces beneath the arena, which have no openings to allow natural light into.
09.00AM JUNE 01 2020
ARTIFICIAL LIGHTING In the evening when less natural lighrt is available the artifical lighting creates a more enrgised and lively atmosphere, which is integrated in the ceiling structure.

ACOUSTIC ANALYSIS
Open spaces
OPEN A.02
Analysis of the different sound sources found around the building and its interaction. The acoustic analysis is based on the hydraulic openings being open to understand the full acoustic possibilities. The primary zone for high levels of sound will be in the performance arena, thus it is important to note when sound levels should be reduced, the hydraulic roofs should be retracted. There is also a seperation between sound levels based on public and private functions of the building, where the private zones are focused on being closed interior spaces to enable comfortable environments for staff.

ACOUSTIC STRATEGY Acoustics will need to be carefully considered in the process of constructing the project, as well as the noises generated from the project when active so that it does not create any major disturbances or conflicts with the existing activity of the site. The diagram map below shows the current noise pollution in proximity of the performance and wine bar arena location. The highest noise pollution is caused by motorised vehicles, which is planned to be reduced through proposed pedestrianisation. Second to traffic noise pollution is the noise pollution cause by parks and more dense public zones which lays between 55-75dB. This association with public spaces makes it a suitable area to aim for, thus the noise pollution produced by the performance arena should be kept between 55-75dB. In order to do so, the hydraulic openings can be closed during events with louder sounds, however acoustic considerations within the perfomance arena have been taken to recuce the transfer of sound out of the building. These considerations are the acoustic panels in the ceiling, which are made of timber panels which absorb sound waves better than the steel structure. The acoustic panels are also nestled in indented surfaces to allow for the sound to bounce of the multiple surfaces.
< 50 - 55dB
55 - 75dB
>75dB
SITE NOISE POLLUTION The map highlights the noise pollution (measured in decebel) that occurs within close proximity to the chosen site. The range of noise found in social spaces appears to range between 55-75dB, thus the project will make considerations to keep in line with this band.

he focus of this year’s work is the awareness that architecture can affect at deepest systemic leveland the understanding that architectural proposition is in itself a system of interrelated constituentswhere the findings of interdisciplinary systems theory apply. This knowledge opens a way to a method-driven approach that can materialize in architecture of great performance and considered expression while driving architectural authorship and novelty. We will aspire to reinstate the designer’s engagement with all aspects of the system’s constituents aiming for impactful architecture delivered by the negotiation of the interacting entities that define the unified spatial whole. Societal, technological, cultural, economic as well as political developments will propel our investigations with a deep understanding of how they interlink. This will shape our strategies and heuristics, driving synthesis. The observation as well as re-examination of civilizatory developments will enable us to project near-future scenarios and position ourselves as avant-garde in the process of designing a comprehensive vision for the forthcoming. We will find out about how human endeavour, deep desire and visionary thought interrelate while they advance cultural as well as technological means, driving civilisation as highly developed organisation. Futurist speculation inspires and ultimately brings about significant change. Supported by competent research we will aim for systemic impact and amplify found nuclei into imaginative tales with architectural visions fuelled by speculation. Our methodology employs both bottom up and top down strategies in order to build up sophisticated architectural systems and will be tailored to the individual problem. Pivotal to this process and to fight charlatanism is the concept of practical experimentation – and intense exploration through both digital and physical models that aims to assess system performance and its direct application to architectural space. The emphasis on applied research fuels the process of design and allows us to develop highly considered architectural propositions with great momentum.
