Brettus,
Framing is simple enough, what we do when we buy something like this, is apply for planning permission, in this case an extension plus another house in the rear.
While the bureaucracy procrastinates, we measure up for what we intend to do and as decision time gets closer, we take specific measurements for the extension.
Once approved, I order timber etc as we make our own wall frames, then order roof trusses from a manufacturer; contact my Sparky, plumber and concreter to let them know something is going to happen (finally!)
In this case we needed to remove a tree and a concrete porch base, so I loaded the backhoe on the truck and moved it on site. Once the site was clear I was able to dig the footings for the slab, and it has progressed from there.
We made a bit of progress today despite mum having to return home the last couple of days, as our son ended up back in hospital again with diabetic complications.
Still waiting on the power mob to change over to the new fascia before we can put the roof on.
Brettus, I am happy to pass on what I have learned to you, just ask.
