Structural System - Primary Structure

Ground Floor Plan The highlighted area indicates the Birch Timber frame that forms the primary structure



Section

The primary structure is here highlighted in red to illustrate how it is a major feature with in the building. Due to this compartmental aspect of the design, it is easily possible to use these spaces as storage areas. This is achieved via shelving or with built in draws / cupboards



Loads are distributed along the beams. Down the vertical columns. From there it is transferred into the slab foundation

Structural System - Primary Structure; Dead Loads


Structural System - Primary Structure; Live Loads

Live loads are spread through the building a number of different ways:


Live loads are spread through the building a number of different ways: Directly through the floor and in to the foundations



Live loads are spread through the building a number of different ways: Directly through the floor and in to the foundations. On the mezzanine loads are spread both horizontally and vertically along the stainless steel frame work into the primary structure.



Live loads are spread through the building a number of different ways: Directly through the floor and in to the foundations. On the mezzanine loads are spread both horizontally and vertically along the stainless steel frame work into the primary structure. Additional live loads, such as snow, is taken through the roof, and on to the primary structure



The secondary structure is a series of 3 vertical beams situated in between each primary structure. These are tied together horizontally across the exterior of the width of the structure. These are attached to a series of horizontal beam perpendicular to the primary system on the roof which all acts as bracing on the primary structure.

Secondary Structure – Live Loads

The secondary structure spreads loads in the same way as the primary structure. Spreading from the centre and down through the three solid walls of the exterior to the foundations.

Ground Floor



The building is cooled with a passive ventilation. Air drawn through building via the Air source heat pump and filtered in a ventilation box is then passed into the building at a low level providing constant cool air.

Environmental Considerations - Cooling

The structure is heated via and underfloor system which maximises interior use-ability and allows for a greater dispersion of heat across the space.

Environmental Considerations - Heating

Once the room is heated the hot air rises to the top of the structure. is passed back through the system. This is a closed circuit system.

Environmental Considerations - Heating

When the hot air rises it is passed back through the passive cooling system. This is a closed circuit system. And allows for more energy efficient cooling.

Full Glass Doors Extends the full width of the west face allow a large amount of daylight into the building.



Roof Light Two raised roof lights permit a large amount of light to reach the above maisonette and some of the lower sections without affecting the structural rigidity.



East Facing Slot Windows These east facing windows allow light to protrude into the stair space. The coloured panels also allows some of the light to penetrate into the main space.



East Facing Slot Windows These east facing windows allow light to protrude into the stair space. The coloured panels also allows some of the light to penetrate into the main space. The fire exit door is completely glass, to enable as much light to enter the main space as possible.

Electrical lighting is provided as a compliment to the vast amounts of natural light that enters the building.

A typical Air Source Heat pump could save up to £330 Generates less Co2 than conventional heating systems Easier and cheaper to install than a ‘Ground Source Heat Pump’

The structure is mostly timber, specifically birch ply.



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.'

A sort of romantic notion that ties hand in hand with the fact timber is one of the cheapest sustainable materials.

Stainless Steel: There is a low level use of stainless steel in the building



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.



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.



Acrylic: There is a relatively large use of acrylic in the build as it is highly durable and when use effectively creates a clever alternative to glass.

Unlike other plastics, foams etc. the shavings and off cuts left behind in manufacture can be easily recycled and formed into new products.



Conclusion

So, how successful was the project, from brief to completion?


Conclusion – Negatives

Photovoltaic Due to the low lying nature of the surrounding buildings, and the design of the roof, it could have been possible to have added Photovoltaic panels to have helped generate power for the extension, and possibly the existing structure as well.


Lighting The use of natural light, and smart lighting systems was a huge selling point of the project, yet when we visited on a bright November’s day, all of the lights were illuminated inside. The user override feature while useful in certain situations seems to have negated this aspect of the design.

Conclusion – Negatives


Mezzanine As the building was designed as a library / music room for ages 4 through 11, it seems as if little thought has been given to the design of the mezzanine. All around the edges there is a 40mm gap which falls full length to the floor below. Although not a large gap, it is still big enough for a child’s arm or leg to fall through.

Flooring Whilst at the sight, 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 ot mark very easily, resulting in both pupils and staff having to remove shoes before entering.

Conclusion – Positives


Sustainability The building has made a very successful use of sustainable materials and has even managed to be 20% more efficient than the intended target. This has been due to materials used in the construction process along with the environment systems that are currently in place. The use of locally sourced materials has meant that there was a reduced CO2 output.

Surroundings The building also made a strong connection with the existing landscape, responding to light and shade well. The additional works done during the development have only severed to root the building in to its environment, providing a strong contrast with the existing school structure, with out overpowering it. The use of the canopy allows the building to be used as an indoor-outdoor venue, which also increases the overall floor space of the structure.


Overall, the structure has been very successful; receiving the Stephen Lawrence Prize from the RIBA, along with the hugely successful low carbon, and sustainable features of the building, while are all commendable, it is through the success of the brief and the experiences that the pupils are now able to enjoy that the “human” success of the building can be measured. Whilst visiting the site, the Head Master commented that they were very pleased with the results, and that is has been much enjoyed by the pupils and staff alike.
