I am planning two modifications to a recently acquired victorian house. I want to convert an existing bathroom to a shower room, plus install a window to provide natural light and ventilation.
I also want to convert an existing bedroom, to become a smaller upstairs bathroom, plus an extended adjacent landing area. The new bathroom will have a new window, replacing a rotten one, and the new landing will also have a new window, to provide natural light onto the larger landing.
My questions are: does either or both of the shower and bathroom required forced ventilation ( both will have windows) and do any of the 3 windows ( 2 new, 1 replacement) need building control involvement ?
