The roof construction
The standout feature of the house is the exposed roof structure. It needed focused hand-crafted attention on every exposed mitre to the build-up of the roof. Which is probably better associated with 2nd fix cabinetry. Rather than 1st fix usual roof construction.
The ironmongery includes the use of concealed joist hangers with steel pegs, which needed mortising carefully with a chainsaw into the 9 X 3-inch joists.
The compound mitres needed honing with hand tools because of the size of the joists. The visible ring beam has been fixed with a countersunk and a bolted method to the internal framework of the building. These have been carefully located behind each of the roof supporting rafters. Each rafter has been fixed with another counter sink fixing which is completed with a glued in pellet and sanded flush to complete on hiding the screw fixings. This assembly took time, thoughtfulness and skill.
In between each rafter, fixed in is 18mm Douglas Fir ply, with secret fixings above. Supporting the 70mm insulation. Exterior 18mm ply fitted to the top of the joists which is then sandwiched with further insulation and another layer of exterior 18mm ply. Before roof membranes and cross batten work to complete. These are the layers of timber work that has gone into the embedded architect’s design.
