ambivalent about merely appending a facade to a structure whose plan and sectional form was predetermined, even saying that: ‘Design architect Niall McLaughlin declared it pure facadism. But we felt there were ways to strike a balance between monolithic structure and diversity achievable with different facades.’ As BLL design director for the Athletes’
with slab to slab heights running at 2.89m. Column centres were set at 4m, running in line with the face of the floor slabs at their perimeter. At the interface of the townhouses with the apartments above, transfer beams allow the apartments to break free of the 4m wide townhouse module. The 10 blocks, a third of which are affordable housing, are served by 60 cores. The concrete sub-contractor slipformed the floors, and once they were up and running, one was cast every 5-6 days. Then it was a case of liaising with the 15 architects to create facade treatments. Due to the accelerated programme,
the project was originally to be procured using Construction Management, but when the economic crash in 2009 forced the government to underwrite the whole development, it moved to Design and Build in what was termed ‘Tier 1’ projects. ‘Block N15 was already being built and became a test case for the rest of the scheme and the first in the development of a precast language,’ recalls Will MacDonald, senior facade manager for Bovis Lend Lease. ‘And lessons learned from the initial CM route effectively became the Employer’s Requirements.’ Fletcher Priest’s Kendall recalls that initially architects were
Village Steve King explains, a number of constructional and elevational constraints set by the Employer’s Requirements came into play. ‘We were explicit about the guidelines for architects, including writing the performance specs for the facades to make sure they met Code Level 4, which involved tempered air and heat exchange. The thermal model we developed came up with a 30% ratio of glass to wall, and we insisted on an 1100mm transom height for the tilt and turn windows,’ he explains. They were also told overheating was an issue and that meeting the ‘g’ value for heat gain would be a greater concern than the ‘u’ value. King adds that the facades are all high-performing, ‘designed to achieve 80% efficiencies, over the SAP 2005 requirement of 44%.’ For visual diversity different architects worked on different parts of the same block. Block N15 brings together Glenn Howells, Niall McLaughlin and Piercy Conner. The design team drew up composite elevations with mock-ups of facades, and blocks were discussed side by side and reinvented by the Village Design Board, the Design Review Panel and planning authority. Kendall says this was because usually ‘you’d want to understand context, but there was none, all the neighbours were virtual’. But every block has both market sale and affordable housing embedded in the design– and there’s no external distinction in tenure mix, although internal unit sizes might
