The bedroom had the same fake beam/lowered ceiling treatment as the other rooms and also benefited from one baffling fake Tudor wall with rough plaster between a grid of dark brown wood. We did the this room in the summer of 2020 after lock-down boredom and an exploratory "lets just drill a little hole in the ceiling to see what the original one looks like" escalated into full blown demolition.
Unfortunately after the lowered ceiling was taken down the original lath and plaster one had to come down too as the joists were broken and needed replacing so it was a messy job. There was a lot of swearing as we shoveled up the sea of rubble in here as we had said we would leave this room for at least a couple of years.
Getting rid of the Tudor wall was a bit of a win as on first inspection we had thought it was structural (i.e. that the stud wall had been varnished and filled in with rough plaster) and it was so close to the doorway there would have been no room to board on top. But after a bit more poking we found we could remove it. Huge relief. We had discussed all-sorts of ways to try to get it to blend in and hadn't managed to agree on anything so this nice flat normal wall now brings me a lot of internal high fives.
We did the new joists ourselves and boarded the ceiling and then waited. And wait and waited... for plaster to become available again. And then it was done! Walls, paint, carpet. And moved the bed back in, a mere three months after we started.
We did the walls in Mizzle, it is very nice. I have no clue about interior design but I think we are going for a vaguely wicker/natural sort of thing in here. Six months later and still no decision on what to put on the walls but I think we will sort some from our amazing trip to Iceland last year, maybe black and white, and put them in frames so we can enjoy a reminisce with our morning coffee.
(Spent a lot of time in the carpet shop specifically attempting to choose one that doesn't do the hoover marks which is a pet hate of mine. It still does :o( but it's so boingy and soft, I have just about forgiven it. The key is not to hoover very often.)
