I installed a bunch of blocking on the interior for bathroom and stairway grab rails, the shower partition glass, kitchen cabinets, the wall-hung microwave, and the heat pump head unit.
Using 2×6 gives plenty of surface area to later play around with layouts.
I photographed and wrote-down the heights and locations of all the blocking so later I can still locate the blocking when the drywall is up.
I also installed blocking in one corner of the living room where I plan to install a wall hung table and chairs.
Because the blocking has to be quite precise I selected the following table/chairs and did the whole layout before adding the blocking.
It’s an Irish company but they ship to the US. If I manage to find a local company then I’ll be constrained to my blocking.
