So having realised that the fragmented nature of work on the build means that roofing isn't going to happen in one go, and accepting the likely onset of bad weather before long, I decided to put a temporary roof of d.p.m. (damp proof membrane) and roofing lath over the structure. This can be rolled up to work on the roof, but means that the inside space is now relatively dry and timber can be kept in better conditions without spending a long time each day uncovering/ recovering materials. Although the d.p.m. is much tougher than the polyethene used to cover the walls, it will still be vulnerable in high winds so I'm looking to get the roof on asap. External wall insulation work continues, as well as prepping for the installation of windows and doors.
A great weekend, thankfully dry, spent with lovely members of the former Nautia housing co-op who came along to lend a hand. Floor joists were fitted at the north end allowing us to lay out sheets of ply to form a safe working platform at either end. The remaining purlins were raised into place and secured - almost at the end of the big-section timber jobs. So really satisfying and definitely getting a feel for the spaces. Now the big question is one of prioritisation in terms of weather proofing - whether to consolidate what we've done so far, or to crack on with the roof. I want to avoid the ply getting wet, especially on the outside where moisture could get trapped by the foil faced insulation that'll go on next...
Mike Hawkins is a co-op member and is responsible for the design and management of the build. He'll also live in it when its finished - hooray! He teaches future architects at Leicester DeMontfort and Birmingham City universities.
