when viewed from the surrounding streets. Both board types have thirty degree chamfered tops and bases to aid shedding of water and to prevent staining and warping. The boards are fixed with a gap between them small enough to prevent water ingress but large enough to allow air to circulate around the timber. A subtle detail occurs when the horizontal timbers wrap around the balconies where the thinner boards are omitted to allow a greater degree of transparency to these outdoor living areas. The timber envelope achieves a U-value in excess of 20% above Building Regulations and all timber is from FSC-certified sources. Inside the building a series of prefabricated glulam arches form the community centre roof structure. This runs from the community centre’s first floor hall, over the building’s double-height foyer and out into the public plaza, forming a generous entrance canopy. The roof, or ‘armadillo’ as it is now known locally, curves across both its width and length. These arcs were carefully calculated from a series of sectional studies and consultations with local planners to ensure generous amounts of daylight into all the adjacent flats. The bespoke Douglas fir ceiling runs from the community centre
and café over the triple-height health centre entrance atrium and into a GP waiting area, uniting the three spaces spatially. It is made from Douglas fir timber boards treated to Class 0 surface spread of flame and, like the external larch cladding, two different profiles of timber are employed to create texture and shadows across the ceiling surface. This also enables lights and ventilation grilles to sit neatly within board widths.
