Double purlin eco-frame goes together
A beautiful opening in the weather coincided perfectly with the assembly of this medium sized frame. Once again, entirely constructed from locally sourced timber.
The variety and quality made this a real challenge, some very brown oak sections and large knot holes made orientation and timber placement tricky.
This has a relatively simple wall design, but the roof makes up for it. The design was primarily client designed, though we advised on some particular details and tweaks things slightly to optimise layout.
They opted for a curved queen strut truss, with standard studs on the gable for simple glazing.
The most striking feature is the addition of another purlin run, with wind braces wherever possible! This means there are eight wind braces in each bay, certainly enough to stop it falling over!
Quite a few of the timbers were brown oak, with varying degrees of flecking and dark staining. We always check whether this is acceptable to use this timber in the frame, as sometimes it can contrast significantly from regular green oak, which is typically quite pale. See below gable rafter.
A nice touch was the addition of some post chamfers.
The final build utilises myriad of eco-build products to get the insulation value up to a standard close to passivhaus. With a thatched roof and lime rendered walls, this frame will blend in its surroundings perfectly.
