一个独立的Bugalow，想隔一间房间出来在客厅的一侧，但是需要一个窗子，不知道要不要跟council 申请，谢谢啦
I don’t think what you want to do is something naughty.
You do not usually need to apply for planning permission for:
repairs, maintenance, and minor improvements, such as repainting window and door frames
insertion of new windows and doors that are of a similar appearance to those used in the construction of the house (note - a new bay window will be treated as an extension and may require permission). If new windows are in an upper-floor side elevation they must be obscure-glazed and either non opening or more than 1.7 metres above the floor level.

太感谢了！
