Holbeck in the 18th & 19th centuries was the cradle of the industrial revolution in Leeds, manufacturing machinery for companies across the world utilising the nearby beck known as ‘The Hol Beck’. Holbeck is now a rundown, unsafe, poor residential area, with over 45% of the population in poor health. My vision capitalises on Holbeck’s water re-branding the district as a symbol for healing and revitalisation, a Spa Town resembling that of Harrogate, as it was once known....

The Site

Adapting the redundant viaduct not only as a connector for people coming to Holbeck from the train station but also creating a pool on it as a major attraction, making it an ‘Aquaduct’ of sorts.

The Masterplan Hol

Creating a secondary route linking the green link to the route which runs along the Hol Beck has led to the positioning of the spa along this route, where historic Holbeck used to be, where the Hol Beck and Holbeck Brook converge as well as being located near the viaduct to utilise the ‘Aquaduct’.

Note: new development is shaded

Bec

The new square creates a connection with the grade I listed Temple Works, celebrating it as a public museum and creates a destination on this new public route.

This green link resolves a key issue of pedestrian links in Holbeck, connecting the residents to Holbeck’s industrial heritage, the Urban Village and beyond to the city centre.

The locations of the underground watercourses 12

Despite popular belief, the Holbeck Brook (also known as Benyon Beck) appears to be the original line of the watercourse and was culverted between 1865 and 1890. It runs into the River Aire below the Asda headquarters as shown in the maps above. Based on the date the Holbeck Brook was culverted, it would only be 6-8m deep in the ground and would be cylindrical. The Hol Beck appears to be a constructed watercourse and was canalised in 1840â&#x20AC;&#x2122;s. It drains via a culvert into the River Aire by Victoria Bridge. Hol Beck goes underground Both becks were used for the steam powered mills in the residing area.

Hol Beck Brook joins the River Aire below the Asda headquarters. 13

Connections â&#x20AC;&#x2DC;When everything is possible, when there are no restrictions to our imagination, then we must impose these limits on ourselves. Without these limits, without the concept of intellectual as well as physical restraint, we cannot hope to find architecture that has meaning.â&#x20AC;&#x2122; D.Chipperfield

City

A happy accident led to the discovery of a secondary route to the city along the Hol Beck reinforcing the concept of making the water a main feature of Holbeck. Developing a destination along the route perpendicular to the viaduct was the driving force of the scheme. 15

Deep Geothermal Energy Capitalising on Holbeck’s underground aquifer water supply as was once done by the mills during the Industrial Revolution has provided to potential for the spa to exist in the first place and has led to an energy strategy to heat up the water using a Deep Geothermal process creates hot water for the whole of Holbeck for free.

Heat Exchange

Due to the fact the aquifer in Holbeck is not a natural hot spring, the heat and energy is generated using ‘Deep Geothermal Energy’ (a completely sustainable solution, currently being done by Newcastle University). Once the water is extracted, the water is the pushed 3-4km down through hot rock generating electricity and district heating which can supply up to 300-400 homes. The heat generating process has no variables such as weather and the only disadvantage is the cost off drilling so far into the ground.

What is a Spa?.....

What is a Spa? A Spa is a machine for bathing. Even in ancient times, spas were highly technical buildings with practical and ritual traditions. It’s cultic origins are speculated to originate from Scythians (Iranian Nomadic herdsmen) who then teach the Greek baths, the Romans take inspiration from the Greeks and is adopted by many a different culture (Jews, Finnish, Russians) modified and the process is articulated based on their beliefs.

The Jewish people incorporated it into their beliefs, calling it the ‘original bath of immersion.’ Uncleanness the symbol of death, cleanness the symbol of recurring life. The Germans consider Spa to be a cornerstone of the country’s health service, whereas Britons still feel embarrased by the idea of being pampered. The immersion in water as a religious rite exists in the oldest cultures and all over the world, whether the aim is cleansing of one’s sins or purification as a prerequisite for rebirth.

Bathing is a ‘ritual purification with water.’ A ‘Water Temple’ for the mind and soul. Relaxation and social interaction (communal bathing) are integral to the Spa process.

The Roman Therme was a place of enjoyment for the people, therefore this term does not correspond to the concept of health resort in the present-day sense. Sweat -

opens pores and allows deep seated grime and dead cells to be flushed out.

Heat

causes an increase in blood circulation, bringing more oxygen and nutrients to the skin surface and damaged parts of the body.

Cold

stimulates circulation, the lymphatic and immune system.

Water & Steam are essential elements. 5 Senses; sight, smell, touch, hear, taste. Relieve suffering from rheumatism, arthritis, skin disease, joint pains.

Russian Bath (Banya) Banya is a Russian wooden bathhouse which these days would be known as a Sauna. In the earliest of Banya they would warm the bathhouse to extreme heat, then undress, and after anointing themselves with tallow, they take young reeds and lash their bodies. They actually lash themselves so violently that they barely escape alive. Then they drench themselves with cold water, and thus are revived.

day (about 60%) and the temperatures usually do not exceed 80째C. Russians pay special attention to the quality of steam: by throwing water on stones heated to extreme temperatures behind metal doors, they create steam droplets of exceptionally small size; this makes breathing easy and enjoyable.

Russian Baths are often located adjacent to Turkish Baths but must be taken on their own rather than combining the two. Sauna Russians believe that hot and dry sauna will only dry your throat and skin. And high humidity baths with heavy drops of water in the steam are also not healthy Russian bath has the same levels of humidity as the air we breathe every 40

Finnish Bath (Sauna) The Finnish Sauna is a substantial part of Finnish culture. For Finnish people the sauna is a place to relax in with friends and family, and a place for physical and mental relaxation as well. Finns think of saunas not as a luxury, but as a necessity. The Finnish Sauna is the hottest type with only about 5-10% humidity, allowing for boiling temperatures (up to 100째C) to be tolerated and even enjoyed for short periods of time. Taking a sauna begins by washing oneself up and then going to sit in the hot room. Water is thrown on the hot stones topping the stove used to warm up the sauna. This produces steam which increases the moisture and heat within the sauna. When the heat begins to feel uncomfortable it is customary to jump into a lake, sea, or a swimming pool, or to have a shower.

Japanese Bath (Sento) Sento is a type of Japanese communal bath house. Traditionally these bath houses have been quite utilitarian, with one large room separating the sexes by a tall barrier, and on both sides, usually a minimum of lined up faucets and a single large bath for the already washed bathers to sit in among others. Japanese find social importance in going to public baths, out of the theory that physical proximity/ intimacy brings emotional intimacy, which is termed skinship in Japanese. Others go to a sento because they live in a small housing facility without a private bath or to enjoy bathing in a spacious room and to relax in saunas or jet baths that often accompany new or renovated sentos. Sentos use heated tap water. 42

Japanese Bath (Onsen) Another type of Japanese public bath is Onsen, which uses hot water from a natural hot spring. They are not exclusive: A Sento can be called an Onsen if it derives its bath water from naturally heated hot springs. A legal definition exists that can classify a public bathing facility as sento.

Geothermal Pool

Due to Japan being a volcanically active country, there are thousands of onsens (Japanese for ‘hot spring’). Onsen were traditionally used a public bathing places. Onsen come in many types and shapes, including outdoor and indoor baths. Japanese often talk of the virtues of “naked communion” for breaking down barriers and getting to know people in the relaxed homey atmosphere. Onsen is all about engaging with its natural surroundings. Onsen use geothermally heated water. 43

Roman Bath (Thermae) The architecture of the Romans was, from first to last, an art of shaping space around ritual. Roman baths were a focal centre for socialand recreational activity known as a ‘Bath Culture’. Romans elevated bathing to a fine art, which was a far more complex ritual than a simple immersion or sweating procedure.

shape and form of bathhouses. The Romans constructed ‘aqueducts’ providing enough water not only for domestic, agricultural, and industrial uses, but also for their leisurely pursuits. There were dozens of different communal pools, each with a different form and theme. Roman bathhouses contain a series of rooms which get progressively hotter.

The various parts of the bathing ritual: Undressing, bathing, sweating, receiving a massage and resting.

Ancient Roman baths used to draw on all surrounding springs as well as rain and groundwater.

Libraries, reading rooms, lecture halls, gymnasiums, physicians offices, perfume selling booths and formal gardens as well as quieter rooms for conducting business became part of some bath complexes.

The segregation of the sexes and the additions of diversions not directly related to bathing also had direct impacts on the

Spa A-Z A aromatherapy

boosting blood flow to the skin.

The use of botanical scented oils to relax the body. The oils may be used typically in massage or facial treatments while inhaling their aroma can help relax the mind.

F flotation tank

Water therapy using mineral hot springs or sea water to relieve physical stress and improve circulation.

Small enclosed water tanks that have salts added to the liquid, letting you float with ease even if you can’t swim. Often you will be in total darkness and silence to allow your body and mind to relax and empty. A half hour float is said to be as beneficial as 8 hour’s sleep.

C chakras

G glycolic peel

From the Sanskrit for ‘wheel of life’, there are said to be seven chakras or energy centres in the body. Optimal health is believed to require the balancing of all seven, and massage is used to help this happen, often in conjunction with crystal healing, where crystals are placed on the appropriate body points to help balance energy flow.

In which glycolic acid is used to exfoliate skin by gently removing the upper dead layers of skin, usually as part of a facial or body wrap. Different strengths of peel are available, so take care as they vary from cosmetic with minor side effects, such as tingling and redness, to clinical strength, which requires a few days downtime but offers great facial resurfacing results.

D dead sea salts

H hot stone massage and hydrotherapy

Salts extracted from the Dead Sea that are added to baths or sometimes large pools to detox the body via the skin and to allow you to float easily, which then enables muscle relaxation and meditation.

Hot stone massage Smooth river stones are heated and used to massage your body, warming and relaxing the muscles to ease and remove tension and knots.

E endermologie

Hydrotherapy This is a treatment that involves water, including Jacuzzis, underwater jet massage, saunas, steam rooms and flotation tanks.

B balneotherapy

A form of mechanical massage that aims to break down cellulite by stretching the tightened fibres in the skin that cause the dimples, releasing trapped lymphatic fluid and toxins while 48

I inhalation therapy Essential oils, herbs and plant extracts are added to steam to allow you to inhale them during a facial or body treatment.

J javanese lulur and jet massage Javanese lulur A flower, herb and yoghurt rub that is applied to your body to smooth and moisturise skin. Then you take a shower, followed by a relaxing and pampering flower petal bath.

A Hawaiian massage technique that uses long overlapping stokes. It is the perfect choice if you donâ&#x20AC;&#x2122;t care for the more intense pressure point therapy. Lymphatic drainage massage A fingertip light pressure massage that works along the lymphatic vessels or your body and into the lymph glands to boost circulation, tackle fluid loss and increase energy levels.

M microdermabrasion

Jet massage Often used at a thalassotherapy (see under T) and hydrotherapy spas where sea or springwater is sprayed at high pressure at your body to boost circulation and lymphatic drainage, tackling cellulite.

Usually carried out with a handheld device that first fires small mineral salt crystals at your skin and then sucks them â&#x20AC;&#x201C; and all those dead skin cells back up again. A little redness can occur but this usually subsides quickly. A great treatment for blocked pores, light scarring and breakouts.

K kneipp therapy

N naturopathy

This aims to boost circulation by alternating hot and cold water therapy. It usually includes putting your lower legs into warm water for a minute and them into ice cold water for a minute, repeating a number of times. The treatment boosts circulation and lymphatic drainage and can be a lower or full-body treatment with the aid of hot cabins, whirlpools and plunge pools.

The use of plant extracts and herbs to treat the mind, body and skin using baths, massages, inhalation and compresses and wraps.

L lomi lomi and lymphatic drainage massage Lomi lomi

O oxygen facials These deliver fresh oxygen to the skin via creams and infusions, firing the gas directly at you with a cocktail of vitamins and antioxidants. Oxygen facials are also usually deep cleansing and offer extraction to unblock pores and blackheads, making them beneficial for almost anyone living in the city. 49

Spa A-Z P paraffin wrap and pressure point massage Paraffin wrap Paraffin wax is heated and then brushed on to your skin before the area is wrapped in clingfilm to allow the skin to absorb the moisturisers in the wax. This treatment is common during manicures and pedicures to soften dry skin. Once cool, the wax is easily peeled off. Pressure point massage This aims to tackle muscle tension, release lactic acid knots in the muscles and to rebalance energy flow throughout the body. The technique involves the therapist pushing into the muscles with their fingertips, elbows and hands and does not normally involve long, traditional massage movements.

Q qigong An ancient Chinese healing system that aims to rebalance your energies. It can include tai chi movements as well as herbal poultices and massages, meditation and breath awareness.

R rasul and reflexology Rasul This is a humid and heated room where you apply different muds to your body to encourage your skin to detox while you relax and inhale the scented steam. The treatment is often offered as a couples option, letting you apply the mud to each other. 50

Reflexology A deep pressure-point treatment, usually on the feet, that aims to unblock energy pathways and aid good health.

S salt scrubs and seaweed Salt scrubs These combine sea salt with oils to exfoliate your body quickly and easily. They are often used as the first step of many body treatments, helping moisturisers, anti-ageing creams and wraps to work more effectively. Seaweed Often powdered and used in baths and wraps because it contains alginic acid, which binds to toxins to remove them from the body by encouraging you to sweat.

T Thalassotherapy A series of treatments, including massage and baths, using fresh seawater. This is usually offered at spas in coastal locations and is particularly popular in France.

U â&#x20AC;&#x2DC;uâ&#x20AC;&#x2122; time Your spa time is also valuable you time, which means that while spas can be enjoyed with girlfriends and partners, they are best experience alone, letting you clear your head, be calm and centred and relax.

V vichy shower A series of overhead water jets that massage your body while you lie on a therapy bed. Often used as part of body wrap treatments as it allows removal of the wrap without you needing to shower. W watsu A Japanese fingertip massage carried out while you float in water with your therapist by your side.

X x factor As much as you may try to quantify and analyse your treatment, some therapists have that ‘X’ factor – sometimes called a healing hand, but often just the ability to connect with people as they treat them. If you meet a therapist with this rare gift, be sure to let them know and book them again.

Y yoga Many resort and destination spas offer yoga because it stretches the body through a series of asanas, or poses, letting you empty your mind and relieve stress.

Z zen A state of mind found within the Buddhist philosophy which means that you are centred, calm, controlled, relaxed and yet also energised. This is our aim at the end of any spa visit. 51

Precedent: Therme Vals - Peter Zumthor Vals, Switzerland 1996

Therme Vals water is supplied via a well to a local spring next to the hotel providing 370 litres per minute. Thermal water is conducted to the baths via 2 chrome pipes (10cm in diameter). The continuous flow of thermal water maintains the 360 cubic metre freshwater reservoir below the indoor pools. Water flows in unrestricted above the water surface where it comes into contact with the oxygen in the air for the first time. The iron dissolved in the water, oxidises precipitating a rust-red deposit on the floor on the 4m deep reservoir. The reservoir feeds the pools with thermal water, from which the iron content has been extracted. It flows through the brass outlets set into the walls and runs off again over long, narrow stone channels at the top of the steps to the pool. The pools are completely emptied, cleaned and refilled once a week, on different days for each pool.

Bath Spa is the modern interpretation of the original spa, extrapolated up to form a 3 storey cube wrapped within a glass skin to reflect the surrounding buildings and topped with a roof top pool. The rooftop pool is supplied via a cylindrical tank with circulation wrapped around and is concrete with a hydrophobic and pore blocking ingredient to make it waterproof. A paint-on epoxy coating provides a further waterproof layer, although problems with it peeling occurred due to inprecise specification, coordination and application.

The Mortensrud Church is an addition to the existing ground and is carefully designed so as not to interrupt the existing topography and vegetation. The main structure is a steel framework with a stone wall carrying the roof. A glass facade off the stone wall defines a narrow gallery around the church room. The stone in this wall is without mortar, thus letting light through creating a brilliant twilight effect. The stone wall is stiffened horizontally by steel plates that span between the columns. The glass facades are stiffened with propels made from steel plates inserted into the vertical joints between the glass panes and the horizontal steel plates in the stonewall. Basic contruction techniques used to great effect, creating rich architecture in a cost effective manner.

Aquaduct

The role of the Aquaduct within the concept of a Spa? The Romans constructed â&#x20AC;&#x2DC;aqueductsâ&#x20AC;&#x2122; providing enough water not only for domestic, agricultural, and industrial uses and thermae.

Aquaduct

250m

Hot spots needed in order to heat the 250m length of water.

Each hot spot could have a different theme.

Aquaduct 10m 100m

Cut down in size due to a lack of justification for a 250m long pool.

Due to the vast size of the Aquaduct (8m x 100m) it will be heated with hot spots every 10m meaning some areas will be cooler than others enforcing the Roman ethos of communal bathing. The outside temperature needs to be a minimum of 36Â°C and a possible cover may need to be attached overnight so the pool doesnâ&#x20AC;&#x2122;t freeze (particularly in winter). Due to its location it will be serviced solely by the Geothermal plant next to it whereas the remaining spa pools will be serviced via a separate plant room.

Programme Analysis Programmatic Arrangement 1. Orientation and Entrance The building is organised so that it can be accessed directly off the main access route through a narrow and shallow corridor to discombobulate the senses before entering an entrance of grandeur. 2. Cafe & Garden The public Cafe is located adjacent to the reception and can be accesed without entering the Spa specifically. The garden is accessed from the cafe but also creates a semi-permeable boundary between the Spa and all subsidiary routes. 3. Changing & Spa The changing and spa are accessed at the lower level, making it more private. Once changed, the spa is entered through the arches at the lower level, making it quieter and light can be controlled easier. 4. Aquaduct The Aquaduct occupies the redundant viaduct and is accessed via a spiral staircase which wraps around an external chimney which is serving the pool. 5. Plant Room & Servicing The majority of the servicing is part of the Geothermal Plant which is next to the Spa as it is not only heating the water for the Spa but also for all of Holbeck, as well as producing energy.

Materials Slate (Welsh Slate) Material choice is important for a few reasons. Not only does it need to compliment the grey engineering brick of the Viaduct, it needs to be able to cope with the different temperatures of the water and moisture in the air. It also needs to be both rough and smooth depending on how I want certain areas to seem and feel. Locally sourced. Strong & long lasting. Durable. Can be crafted to be rough or smooth. Fireproof. Low water absorbtion index. Can be slippery when wet.

100

Materials The Polyblock system (Insulated Concrete Forms) The system is in essence a hollow expanded anti-fungal polystyrene block that acts as formwork for a reinforced concrete infill and stays in place to thermally insulate the building. The thermal qualities and the tactile nature of the polystyrene blocks make them eminently suitable for swimming pools and their versatility means that the pool can either be lined or tiled. Walls are 50% lighter than equivalent sized brick walls allowing reduction in structural support systems. Plumbing and electrical services can run through the hollow core before concrete filling. Walls can be built up to 5 times faster than normal clay/ cement bricks.

Steam Rooms

The Viaduct arches are ideal steam rooms as they are curved so that condensed steam runs down the walls (with flat ceilings the condensation can drip and possibly cause scalding). As hot air rises, each floor will be hotter meaning the user can choose their preferred temperature. The steam room needs to kept at a constant temperature of 43째C and the engineering brick will absorb and retain the heat therefore steam should never be turned off. The Steam rises up and condenses out.

3D Detail Study Microclimate parameters (dry and radiant air temperature, air speed, relative humidity) can influence wellness and health status of people working inside for long periods of time and must therefore be carefully monitored. The Spa area will be kept at 28째C rather than the standard 22째C and relative humidity should be maintained within the range of 55-65% and specific humidity should not exceed -1 0.016kg H2O/kg p.s. Air speed should not exceed 0.25ms because higher values contribute to increased evaporation of water, and thus a higher air relative humidity. Based on regulations, 4-5 air changes per hour is required for ventilation.

Deep Geothermal Energy Engineers at Newcastle University will today begin an ambitious project to drill 2,000m under the heart of the city in search of renewable energy. In a landmark project that will reach new depths in an attempt to harness geothermal heat from the earth, the Newcastle team hope to eventually pump out water at a temperature of around 80 degrees centigrade. Drilling deep under the planned 24-acre Science Central – the site of the former Scottish and Newcastle Breweries – the team believe that boreholes here will prove capable of supplying an everlasting source of low-carbon energy hot enough to heat any domestic or commercial central heating system. Funded by the Newcastle Science City Partnership and the Department of Energy and Climate Change (DECC), the £900,000 project is being led by Professor Paul Younger, Director of the University’s Newcastle Institute for Research on Sustainability, and involves experts from both Newcastle and Durham universities. “Our aim is to rise to the challenge of putting a novel form of deep geothermal energy at the very heart of city centre regeneration,” explains Professor Younger. “It’s an incredibly exciting project. If we’re right and we pump 150

up water at such elevated temperatures, it would mean a fully renewable energy supply for a large part of the city centre, massively reducing our reliance on fossil fuels and reinforcing Newcastle’s position as the UK’s most sustainable city – an accolade which the Toon has now won two years running. And unlike other renewables such as wind and solar, geothermal energy is available at all times, independent of the weather. Phil Steele, General Manager of Eldon Square, said: “We spend approximately £1.7 million per annum on energy and at present this demand is all met from fossil-fuel sources. We can now look forward optimistically to using deep geothermal energy to supply part or all of our future energy needs and we look forward to working with Newcastle University to develop this major scientific enterprise for the city.” This is the second time in 12 months the Newcastle team has explored the region for geothermal energy. Last year they pumped up water at a temperature of 40 degrees centigrade from a 1,000m twin-borehole at Eastgate, in Weardale, County Durham. If today’s geothermal project is successful it will pave the way for similar projects across the country where it is known similar deep fault lines exist such as Carlisle and the Craven Faults in West Yorkshire and Lancashire.

Tax Incremental Funding (TIF) Tax Incremental Financing is a means of funding public sector investment infrastructure judged to be necessary to unlock regeneration in an area, and which may otherwise be unaffordable to local authrities. An innovative finance mechanism to support local investment and growth. TIF uses future additional revenue gains from taxes to finance the borrowing required to fund public infrastructure improvements that will in turn create those gains. When a public project such as a new road system is constructed within a specific area, increases in the value of land as well as new property and business investment can occur. Resultant increased site value and investment generates increased tax revenues. These increased tax revenues are the â&#x20AC;&#x2DC;tax incrementâ&#x20AC;&#x2122;. A pilot version of the scheme is already underway in Scotland, originating from the United States.
