How much can eaves overhang?
A. The permitted development regulations do not specify how much eaves can overhang. A good reference point, however, would be the eaves on the existing house. The depth of eaves contributes to the overall character of the house and its usually better to follow what’s already there. Having said that, a single storey extension would not be radically out of character if its eaves differed. Indeed, on houses which have quite deep overhangs on the main roof it may be better not the match that depth on a single storey extension.
