Camden Town, London Coffey Architects Library Box St Patricks`s School July 2010 until April 2011 Bolt and Heeks
Project; To provide a Library annex with covered waiting area and walkway, also provide M&E upgrade, above and below ground drainage and hard and soft landscaping After speaking to the school, it became apparent that the Library space was created to provide an area that could be used for a range of activities. It was vital that the space was not overused, or underused, and met specific storage requirements.
St Patricks Catholic School in Kentish Town, London, has won RIBA`s 2011 Stephen Lawrence Prize. It was said to be the best example of a project that was constructed under ÂŁ1 million. It is simply an extension for the school, providing a much needed library and music room. The structure has been constructed from simple materials, mainly steel and timber, with a zinc cladding. the Architects have attempted to create a sustainable building, and there are different solutions to this within the design.

Glulam Timber beams bolted 990m 990m Beams bolted apart provides primary load bearing structure, but are not entirely structurally supportive on their own.
Timber joists add extra structural support, and braces the primary structure so that it has no lateral weaknesses
The cladding provides a final extra bracing system, enclosing main structural elements. It also provides a platform to attach the damp proof membrane.
Structural breakdown Load Bearings Dead Load - structure supporting itself
Loads are transferred horizontally across beams and then down the vertical columns into the concrete foundations
Structural breakdown Load Bearings Dead Load - structure supporting itself
Live Load - supporting changing loads, such as people or contents
Upper level: Mezzanine is hung from primary structure, steel elements sandwiched and bolted between Glulam beams - loads are distributed along equally along the brackets/ supports, then the beams and columns
Structural breakdown Load Bearings Dead Load - structure supporting itself
Live Load - supporting changing loads, such as people or contents
Lower level: Loads are distributed straight into the concrete slab foundations below.
Structural breakdown Load Bearings Dead Load - structure supporting itself
Live Load - supporting changing loads, such as people or contents
Roof: With the roof being flat, elements from the weather may collect there. The load from this are carried into the horizontal then vertical supports.

Environmental Systems Cooling Air source heat pump draws air from the roof, which then passes through a filter within the ventilation box and is released into the building through low vents.
Environmental Systems Heating Underfloor heating was incorporated into the design. This allows for more internal space as no radiators are required. It is also a more effective way of heating a space as it has a larger surface area and disperses the heat equally.

One the air is heated, it rises to the top and gets released through high vents. This is then circulated into the passive ventilation system again.

Environmental Systems User comfort + Energy Conservation The existing school is a highly wasteful building in terms of energy so the architects established that the new build should be as conservative as possible. Fully contextual design was employed to ensure a successfully sustainable school, some clever details are use of the existing cherry tree on the rear of the building to shade the windows and create a more ambient lighting level naturally.

The architects themselves claim this is 'relating the library directly to its microclimate in a way that is only possible from designing the building to suit its particular context.'
Environmental Systems Materials Exterior Zinc Cladding No building is truly sustainable unless it will last a long time, otherwise the energy that went into its construction will be wasted. The exterior of the structure is clad in Zinc; one of the most environmentally sustainable materials. Zinc is 100% recyclable. More than 90% of zinc used in the building industry is recycled. Zinc requires minimal to no maintenance due to its naturally forming patina which is self protecting. It is very resistant to corrosion. Is perfectly water tight. The result of this is a facade that should last a lifetime, around 40 years.

Environmental Systems Materials Interior and Structural timber The structure is mostly timber, specifically birch ply. This is because the project was conceived around a double height book case, which according to the architects 'relates knowledge to external existing/allegorical trees.' Promoting the concept that children can sit under these conceptual trees to learn, read and play music. A sort of romantic notion that ties hand in hand with the fact timber is one of the cheapest sustainable materials.

Birch: - Benefits from a smooth finish easily. - Accurate thickness levels make it ideal for repetitive elements. (left) - Birch trees are the ultimate natural resource with almost every part of the tree being utilised at some stage or process. - Fast Growing. - Abundant in the northern hemisphere.
Environmental Systems Materials Interior and Exterior Steel Stainless Steel: -There is a low level use of stainless steel in the building -Most stainless steel is made with %60 percent recycled material, which means a lower carbon investment in the production. -The Steel in the building is brushed and not polished which also reduces the carbon input in manufacturing.
Environmental Systems Materials Acrylic Panels - There is a relatively large use of acrylic in the build as it is highly durable and when in use, effectively creates a clever alternative to glass. - Although acrylic can be harmful to produce it has a long life span and is fully recyclable. - Unlike other plastics, foams etc. the shavings and offcuts left behind in manufacture can be easily recycled and formed into new products.
Environmental Systems Materials Sarnafil Roof - Provides good insulation - Includes recycled materials - Can be completely recycled after use - Only one single membrane is required to protect building - Helps resist temperature fluctuations within the building

Different structural solutions have been used, such as using the bookshelf as a stair support, which reduces the amount of structural elements required. This in turn allows a larger floor area to become available for use.

Exterior Aesthetics The architects chose to clad the exterior in zinc. This is quite a contrast compared to the traditional brick building that the existing school was constructed from. However, the buildings sit nicely together, with the walls not quite touching, it makes it clear that it is a new generation of building.

Weaknesses
Mezzanine Issues When we first contacted the school, the receptionist we were in contact with noted that the mezzanine could not hold as many people as was predicted, and could only hold 5 instead of the 15 that they were told.

Another issue that was presented to us when we viewed the building was with the flooring of the mezzanine not extending the full width, up to the primary structure. A problem we found with this was the gap between the edge of the floor and the storage. The gap extended to the lower floor and was 70mm wide wide enough for a young child to accidentally trap their foot in.

Solutions
When we first contacted the school, the receptionist we were in contact with noted that the mezzanine could not hold as many people as was predicted, and could only hold 5 instead of the 15 that they were told.
Extra structural components could be added to ensure that the floor is strong enough to hold that amount of people, as long as the roof structure could provide for that. Adding elements that would support from below would prevent full use of the main space.

Possible advances
Photovoltaic panels With the roof being flat, it has the potential to easily add photovoltaic panels to help generate the electricity used throughout the building and possibly supply part of the existing school. However, these can be costly which may be the reason why the school has not incorporated them into the current design.
Possible advances
Flooring Whilst at the site, the Deputy Head Teacher, Miss Thomas, mentioned that the flooring that had been used in the main teaching area has not been as resilient as hoped. It was found to mark very easily, resulting in both pupils and staff having to remove shoes before entering. Laminate flooring can pose problems with markings, and considering that the interior is mainly birch plywood, it may seem unattractive if any other material for flooring was used. A shoe box that could be attached to the walkway could be provided to help tidy up the exterior when the building is in use.
Overall....
I feel that the project was very successful, considering the budgets that were enforced upon them. They have taken consideration towards the environment, moved towards sustainable solutions and have created a friendly, healthy place for children to work and play in. The exterior may be controversial, some may see it as a positive move towards the future, some may see it as a scar on the face of a traditional catholic school, but most architecture that is successful will be disputable. The staff and children at St. Patrick`s were very happy with the results and enjoy using the building. It may at first seem like a simple project due to its size, but there are many complexities within, which, when all working together creates a synergistic space.
