By close of play last Friday - 2hrs after this photo was taken - the ridge beam and both gable walls were complete. During the couple of days prior to this, by quirk of structural engineering design the first floor boarding was glued and nailed in place, the idea being to provide a strong joint between the 1st floor I-beam joists and the binder plate (a deep beam which runs along the top of the ground floor wall panels against which the ends of the joists are butted).
In my (and our joiner's!) view this was quite an unusual detail, but a call to our stuctural engineer - "just to make sure..." - clarified the thinking behind it. The downside was that the T&G chipboard flooring had to be protected from the weather until the building is made watertight, as being merely 'moisture resistant' isn't exactly a qualification for survivablity for up to a month's battering by the west of Scotland's climate in November!This coming week should see the completon of the 1st floor wall panels and start of work on the roof. On the 'goods inwards' front, the windows are due to be delivered this week and possibly the Pavatherm wood fibre insulating cladding board.
