This week the roof was cut in. Can see the spaces for the Velux rooflights and get a different picture of the inside - the vaulted ceilings in the rear living area in particular. The builder recommended a ceiling in the upstairs bedrooms at around the 3 meter / 9 foot mark which is high enough even if you're bouncing on the bed! Still leave a bit of space for storage so may leave a small hatch and floor this area after setting it up. It's a warm roof so this is all conditioned space. Next week
