This is a fairly major part of the whole project - the framing of the new oak frame that will form the basis of the rear extension. Here is a model of the actual frame design. Its made up of 3 bays, with the first two bays forming the dwelling. The 3rd bay will be left open so as to form a full height porch/patio' out into the garden. l'l be making it at the workshop of my friends at Traditional Oak Carpentry. It should take around 5-6 weeks to complete the various sections.
Now that all the cross frames are done its time to turn our attention to the roof - namely the purlins and windbraces which will in turn support the oak rafters. Here the stub ties are being fitted into the wall plates. A dovetail joint stops them from pulling apart. Housings are cut into the principle rafters to accept the purlins. The purlins are cut and seated into the housings, ready to lay out the braces for making. The braces now fitted. The other side of the roof is in
I thought this cross frame deserved its own post because it looks so flippin' awsome! This is the last truss to frame and will form the opening to the full height porch which opens out to the garden - a real focal point of the frame. Its different from the other cross frames in that it has no cross rail in the middle which in turn produces a large open cross frame. Instead it has a long 'sling brace' which holds everything in place. Just like the previous braces and collars
Now that the both side walls are complete its time to begin the first of four cross frames. As usual the main component timbers the make up the cross frame are laid out for measuring and marking. Here the principle rafters and the stub ties have been cut and assembled Now the collar has been cut and fitted The 'H frame' is then marked and cut. The posts have already been out to frame the side wall, and you can see the girder housing which was previously cut into it. Now the
The first sections of the frame to be built are the side walls. We're working on on side wall at a time. Here the joints for 'top plates' have been cut out and the four posts are ready to be marked and cut by transferring the shape of the the top plate down onto top of the post. This is how its been done for centuries. Above is a picture of the tenon and housing for the girder. The girder is a horizontal piece of oak which goes into the posts and will support the first floor
This is last major part of sole plate repair - a nice straight run of sole plate and a couple of posts which have rotted away along the front of the cottage. Below you can see the first post repair and the second one on its way - just in the process of cutting back to some decent oak before the new oak post is spliced in. This is the last piece of sole plate being lifted and test fitted. Once it looks like the adjustments are completed, its taken out, cleaned and lifted back
A quick update with some more photos of the final structural oak repairs in the dining room of the old cottage. These consist of creating a new upper and lower doorway which will give access to the rear extension (both upstairs and downstairs), plus a little bit of repair to support the floor joists of the bedroom above. I introduced a complete new stud on the right hand side which helped to produce a new doorway in the right position and give a little bit of extra support to
