40 PROJECT REPORT: SELFBUILD & CUSTOM BUILD PROJECTS
In one bedroom there’s a ‘Lion, the Witch and the Wardrobe’ moment where a steep fixed stair leads to a secluded roof space
floor utility – there’s an upstairs cupboard for the copious IT and cabling that serves the integrated lighting system and the house’s media via suspended ceiling voids. As well as offsetting the very airtight
design, which is around maximum leakage of 0.4 h-1@ 50 Pa (Passivhaus is 0.6) the MVHR helps to remove cooking smells in the open plan living area. Hill says the team “did a crash course in terms of how to use the air-tightness tape,” and “spent a long time getting the details right, working with consultants, different suppliers and the contractor.”
Other design elements specified for high efficiency include the glazed screen, manufactured by Italian company Ottostumm with a thermally broken frame, making it “a bit chunkier than 1950s Crittall mullions,” says Hill. The initial budget was forced to stretch slightly, with the build cost ending up around £1.1m, but this included all finishes, and sustainability features such as MVHR, PVs, air-tightness measures, and additional insulation.
Appearances
The architect reports that this striking, yet in some senses relatively conventional home hasn’t caused any adverse responses from neighbours, as it “nestles well” in its site. This was assisted by the designers managing to retain a number of the mature trees at the front at the site. With the sintered Dutch brick (from BEA) having a reclaimed look, the exterior helps the building not only blend with neighbours, but also to feel it has existed for a considerable time – the client “didn’t want this sparkling new thing,” says Hill. The brick can be specified down to the ground, as it is F2 and can therefore withstand frost. The ultimate purpose, to deliver a great ‘forever’ family home, has been achieved, and no doubt the Lobbs are very happy. Sean Ronnie Hill says that despite now living in a grand, but very sustainable home, they are “humble people,” illustrated in particular by how they commented throughout the build that they “couldn’t believe they were able to do this.”
