T H E C O M M O N W E A LT H A S S E M B LY A NEW-ERA COLONIAL BUILDING OFFERING SOVEREIGNTY TO THE CITIZENS OF HONG KONG Hong Kong
T
he symbiotic use of concrete and timber is an untapped material hybrid, previously restricted by its opposing material sensitivities. With research developing into Strand Woven Bamboo as a concrete reinforcement, the project can investigate the potential that exists for a fully integrated composite construction.
The Victoria Commonwealth is formed through the consolidation of colonial outcomes within Hong Kong’s society that are cherished today, manifesting a new political structure and serving as a catalyst for citizens to subvert the current manipulated governance of this city.
The building situates itself within a context that still practices highly-skilled bamboo construction techniques, as well as owing much of its recent urban proliferation to concrete. Hong Kong flourishes in examples of hybridised eastern and western features and the duality of these materials aims to consolidate this identity, which a large proportion of citizens are protesting to hold on to. Following a narrative in which the United Nations sanction China for it’s repeated breach of the Sino-British Joint Declaration, Great Britain has a duty to their former colony to serve the citizens and ensure their promises are fulfilled. The choice to retain certain outcomes of their colonial past is a result of the ambition to retain the city’s current identity. A reversal of the British influence could potentially repeat the process of cultural absorption under the new heading of ‘mainlandisation.’ Embracing the combination of eastern and western values should transcend from communal identity into the built environment, taking the democratic style and constructing it with traditional Chinese methods and materials.

THE ABILITY TO CONTROL NATURE Studying concrete’s role in extreme infrastructure
The Hoover Dam offers an example of mankind using concrete to manipulate nature in favour of civilisation. The Dam holds back the Colorado River, filling the largest manmade reservoir in the country. This archgravity dam provides irigation to surrounding inhabitation, spurred an agricultural revolution and generates hydro-electric power. However not without severe damage to the river’s ecosystem and being a contributor to potential natural disasters.

If the Dam were to be poured in a single continuous pour, then the concrete would take 125 years to cool. Resulting stresses would cause the damn to crack and crumble. Requiring a concrete cooling system to be embedded into the construction. The construction for the Dam was formed of a grid of concrete blocks in columns, each contained a series of 25mm pipes where river water followed by ice cold water was poured through. Once the concrete is was cured, the pipes were filled with grout.
6
These columns used both circumferential and radial joints to deal with the converging grid work. The concrete was poured using a newly patented technique requiring buckets of aggregate specific concrete to be craned over the relative form work.

The holistic design consistently relates to an almost skeletal use of structure. The barrel vault uses repeated modular elements at angled/ radial fixings which embodies the vertebrae of the spine, however without a developing variance in each element. Tethered back to sloped columns by a fanned element that share function with ligaments, these load paths repeat themselves down the building creating a series of ‘ribs.’ The ribbed hemispherical dome of the apse also takes the form of a ‘Lamella’ structure, which commonly derives from the porous/ lattice structure within bone marrow.

REINFORCEMENT TYPE Nervi is known for his use of ferrocement and in this case uses it to create the pre-fabricated elements. The in-situ cast elements overlayed are then composed of a system of rebars that help tether the elements together. The main differences stem from the use of smaller but more dense reinforcement elements in ferrocement (wire mesh), meaning its products can be lighter and thinner. The mixture is composed of rich Portland cement mortar and fine aggregate and can be constructed without formwork.

DUAL CONSTRUCTION These elements are also separated by construction technique. The pre-fabricated elements are hoisted into place over a scaffolding frame and once complete, this combination of individual modules creates channels to lay in the reinforcement and pour in-situ concrete reducing the amount of formwork to implement and remove during the construction process. Is this separation of required form vs required mass a technique the architect could use in order to apply the most efficient form of fabrication and material to each?

HYBRID SYSTEM 01 The use of timber and concrete.
The construction process involved with Tudor housing is that of ‘half-timbering’. Involving a framework formed of natural timber with large metal bolt elements acting as connections and a composite of wattle and daub to create a solid wall. The structure in turn expresses itself to either side of the wall, expressing the relationship between timber and the plaster material.

These engineered bamboo huts can be found in many countries that have large resources of bamboo and limited access to steel such as Costa Rica, Colombia, Nepal, Ecuador, El Salvador and The Philippines. Utilising many parts of the bamboo for its relative function, these huts offer a diverse and resilient construction process that is highly sustainable.

EXISTING BAMBOO AND CONCRETE COMBINATIONS Although seemingly opposing materials, cement is often used in addition to bamboo structures in order to achieve certain structural or environmental intentions that bamboo struggles to achieve alone. However with bamboo’s susceptibility to expansion and shrinkage due to moisture, its longjevity as a building material remains questioned. 01
APPLIED PROTECTIVE LAYER
In the form of tile or applied directly to a mesh screen, the cement will offer a protective barrier to the bamboo itself, whilst also providing a barrier to the external environment. 02

Currently being used as a flooring material, famous for its material properties surpassing other standard timbers. The finish also resembles solid timber. Bamboo itself is the worlds fasting growing plant, considered the most eco-friendly flooring material on the market. Out of the engineered bamboo materials it is most material efficient using fibres from all three layers of the culm.

MEMBER SIZE
Size of timber component determining the relationship with concrete The efficient and resourceful use of varied bamboo component in the bahareque housing is translated here into a map of concrete intervention. Depending on the size of the timber element the concrete acts either as a footing for an independant timber column, a canopy application to protect from environment or a solid wall reinforced by the splaying form itself.
14
MITIGATES USE OF STEEL - for both concrete reinforcement or bamboo connection. This further improves the longevity of concrete structures as there is no risk of concrete cancer. PROVIDES A NEW ARCHITECTURAL LANGUAGE - with a transitional continuity mostly seen in concrete structures
now being available to a predominantly timber structure.
REDUCES CONSTRUCTION WEIGHT - an overall lighter structure than concrete so opportunity to building on existing
structures or weaker geology.
TRANSITIONAL ARTEFACT Material hybrid based on gradual member size
15
INTERFACE
Investigating a smooth transition from one material to the next Taking principle from a concrete base for compressive strength and a timber extension for tensile strength, the standard square column is split diagonally. This connection is then manipulated to create a strong buttressing element that has a fluid transition between timber and concrete.
16
FLOW DETERMINATION Reinforcing areas of flow accumulation or diversion
The liquid trends of pooling and release from surface tension are identified on an insufficient timber structural node. These areas identify need for reinforcement and start to introduce the symbiotic relationship between timber and concrete that needs to be achieved.
17
TRAPPING TENSION
Utilising compressive concrete mass to trap timber tension. Here the tensile and compressive qualities of each material are focussed and utilised to create a high strength detail. The timber column splays by the act of bending and a concrete wedge increases compression to the base of the bent timber elements forcing them outwards. However its tension is retained by a concrete hook at the end of each splayed element.

SYMBIOTIC STRUCTURAL BRANCHES Expanding the joint.
Informed by the ambition to expand the weave or the joint to become inhabitable and starting to apply my material research to brief, a symbiotic system is created. Developing a dual stem or dual core, hybrid system based upon the approach of two symbiotic structural branches working in equilibrium both structurally and also starting to introduce architectural influence on each other in an attempt to intertwine and inter-depend the two facets of my programme.

SYMBOL OF VIRTUE The significance of bamboo in China.
To the Chinese people, bamboo is a symbol of virtue. It reflects people’s souls and emotions, an example of the harmony between nature and human beings. One third of all bamboo species in the world are grown in China. South Yangtze River area produces the most bamboo in China. Dai people in Yunnan still live in bamboo stilt houses.
Mapping International Bamboo Growth
Presence of Moso Bamboo Growth Sites of mass bamboo growth gravitate towards the two rivers in the south of China.
Dai Bamboo Housing - Yunnan Still utilising bamboo as a primary construction material, the culm is manipulated to a versatile set of applications from structural members to cladding. The composition of the house raises the ground level to allow for the dwell of cattle whilst the human inhabitation starts on the first floor.
Moso Bamboo This bamboo species native to China produces a large culm and has a rapid growth life of about 5 years until full maturity.

CHINA A site of concrete and bamboo interest. Beijing Tianjin
Chinas connection to concrete is undeniable, with its recent proliferate development and urbanisation giving credit to this catalytic material. With the national urbanisation rate of China reaching 60.6% in 2019 and in turn the demand for cement increasing by 438% over the past two decades, the country is rapidly realising its urban ambition although not without consequence.

MAN MADE // NATURE
A contrasting terrain of preserved nature and a concrete jungle. Embodying the trend of rapid urbanisation, Hong Kong is known for its dense collection of high rise buildings. The city scape creates a maze of public streets embedded deep into the foundations of the its architecture, creating a unique public realm. However this typology is not endless, with a rich and preserved natural landscape occupying 60% of this cities terrain. With strict conservation laws restricting human intervention on the natural realm, what can we do to integrate these two typologies in the urban setting?

ONE NATION, TWO SYSTEMS An anomaly within China’s borders.
Since Britain handed Hong Kong back to China with an agreement of autonomy for 50 years and a philosophy of “two systems, one nation” the seamless handover has not played out as anticipated. This international message from Hongkongers to other democratic countries has sparked ranging global reactions from fear of losing trade with China to lifeboat campaigns for the citizens of Hong Kong to escape the imposing policies of mainland China.

In order to level the playing field, Great Britain are given permission to freely offer services to the citizens of Hong Kong. With attempts such as the offer of the British National Overseas Passport being counteracted by Mainland China, the realisation of a commonwealth centre within the city will allow citizens continued access to the characteristics of society that they once had.

DEMOCRATIC SPACE PLANNING Political Architecture in Great Britain
System of architectural elements in the Gothic follows a branching narrative where every element sprouts from another, an approach that can be carried out efficiently with a bamboo and concrete hybrid. Although these structures often use materials of stone and masonry, timber is sometimes incorporated and has an opportunity to offer greater material capability with modern technologies within the craft.

02: CONSTRUCTION PRINCIPLES Political Architecture in Great Britain
System of architectural elements in the Gothic follows a branching narrative where every element sprouts from another, an approach that can be carried out efficiently with a bamboo and concrete hybrid. Although these structures often use materials of stone and masonry, timber is sometimes incorporated and has an opportunity to offer greater material capability with modern technologies within the craft.
Hammerbeam Ceiling - Westminster Hall Large spanning oak ceiling that allowed for an open, column-less hall with high ceilings and intricate carving.
Timber
Gothic Vaulting - The Cloisters The transition from ceiling to wall/ column was integrated in the Gothic through vaulting. Another technique to allow for tall ceilings, demonstrated in many variations with the fan vault most specific to Perpendicular Gothic. Stone ribs lined a masonry canopy.
Compound Pier
Tracery
Being informed by the ceiling condition, the columns and piers became fully informed and shaped by what sat above it. The shapes and profiles resembled a bundling of structural elements being tied into the vertical element.
Following this branching and dispersing nature of the Gothic style, the stone elements seperate further into tracery which starts to produce the tertiary elements of the structure such as openings, window frames and balustrades.
Flying Buttress These elements intend to free the building envelope from structural function in order to allow for large openings and thinner profiles. Pinnacles are utliised here to add weight to vertical elements to combat the horizontal forces created by large ceilings.

PUBLIC INTERFACE
Exploring the relationship with public further than a window.
PUBLIC CONNECTION
The primary sense that craves transparency, citizens want to know exactly what is going on in their city and be able to contribute something if they disagree.
An influence on both sides with the presence of the public reminding the polticians who they are there to represent.
An ability to contribute to the process may come through the form of a forum, political jury duty or heckling.

CONTINUITY AND ACCESSIBILITY
With a police record of 128,000 at the most recent protest, by HK population:land density, a space of 18000m² is required for this political demonstration. Both Lugard Rd ad Harlech Rd spanning 12,300m² leaving 4700m² to connect the new tram line to the footpath and create a dwell zone for possible political pilgrimage.
The streets within an urban setting offer adquate host for a path of protestors. By applying this familiar dimension to the public space, the platform can be staggered to respond to the site conditions and connect these two public access points.
By applying the required depth to span ratio, a sloping nature offers a winding path that references a more natural terrain and opens opportunity for intervention upon the generous public spans. 1 12

TIMBER REINFORCED CONCRETE Timber continues as a thin framework of reinforcement for an in-situ concrete wall.

EXPOSED BEAMS Creating areas of transparency for the external environment, light or circulation.
CONCRETE UNDERSIDE Used as a surface against the natural terrain, thickening the concrete element in areas that require a retaining wall. Allows space for insulation and services.
CONCRETE INFILL Reinforcement and concrete filling the voids between each beam, to be used in areas that require a solid braced surface without insulative requirements.
CONCRETE TOPSIDE Here the concrete lines the upper profile of the timber beams, acting as a shell to protect from environmental factors. Allows space for insulation and services.
OVERLAPPING SURFACE By integrating the timber within the concrete layer we can create conditions where multiple surfaces overlap in order to serve structural and architectural function such as enclosure or ground condition.
BEAM CONVERGENCE The timber structure converges into a singular element that can act as a column.
CONCRETE FOOTING At site of a connection to the ground plane or otherwise, concrete takes a large amount of compression whilst also enhancing a language of continuity. EMBEDDING CONCRETE By creating a concrete interlayer we benefit from its composite properties structurally and timber can be used internally and externally for secondary and tertiary purposes. However this creates a thick build up that restricts the use and expression of concrete.

BEAM EXTENSION SCARF JOINT
Due to fabrication and transport constraints, sections of the beam will require on-site assembly. The scarf joint here uses only timber and creates a strong extension of the member.
02
CROSS LAP JOINT
03
Where two perpendicular member are to be joined, this joint type offers a seamless solution without a dominantly visible use of steel.
DELAMINATING SCARF JOINT
By adapting the scarf joint, this junction allows for the splaying of a primary structural member creating a separate enclosure or support.

DELAMINATING SECONDARY
Using the same approach as before however continuing into a secondary piece of structure that could support a curtain wall.

G14 is a test bed for architectural exploration and innovation. Our students examine the role of the architect in an environment of continuous change. As a unit, we are in search of new leveraging technologies, workflows and modes of production seen in disciplines outside our own. We test ideas systematically by means of digital and physical drawings, models and prototypes. Our work evolves around technological speculation and design research, generating momentum through astute synthesis. Our propositions are ultimately made through the design of buildings and the in-depth consideration of structural formation and tectonic constituents. This, coupled with a strong research ethos, generates new, unprecedented, viable and spectacular proposals. IAt the centre of this year’s academic exploration was Buckminster Fuller’s ideal of the ‘The Comprehensive Designer’: a master-builder who follows Renaissance principles and a holistic approach. Fuller referred to this ideal as somebody who is able to realise and coordinate the commonwealth potentials of his or her discoveries without disappearing into a career of expertise. Like Fuller, PG14 students are opportunists in search of new ideas and architectural synthesis. They explored the concept of ‘Inner Form’, referring to the underlying and invisible but existing logic of formalisation, which is only accessible to those who understand the whole system and its constituents and the relationships between. This year’s projects explored the places where culture and technology interrelate to generate constructional systems. Societal, technological, cultural, economic and political developments propelled our investigations and enabled us to project near-future scenarios, for which we designed comprehensive visions. Our methodology employed both bottom-up and top-down strategies in order to build sophisticated architectural systems. Pivotal to this process was practical experimentation and intense exploration using both digital and physical models to assess system performance and application in architectural space.
