The ceiling was one of the things I dreaded to do. The moment I actually started I didn't have a real plan. Luckily our neighbour Bas had some good idea's and after some Ctrl-Z (undo) actions the wooden frame looked a bit sensible.
I worked all Sunday to get the frame in and late in the evening Fran and I put the ceiling itself in.
