Side extensions live or die on daylight and boundary rules: permitted development caps them at half the width of the original house and 4 metres high, and within 2 metres of a boundary the eaves must stay under 3 metres.

Will a side extension make my kitchen dark? +
Designed properly, the opposite: rooflights over the side return typically bring in more light than the original window did. Daylight is the first thing we test.
Do I need to tell my neighbours? +
If works affect a shared wall or are within statutory distances, the Party Wall Act requires formal notice. We advise on this as part of the design stage.
