SourceDormers should be subordinate to the roof slope, sit within it and keep even distances to the ridge, eaves and side parapet walls; rear extensions should pass the 45-degree and 25-degree daylight tests and leave a reasonably sized garden (Home Improvements CPG, 2021).
SourceBasements should be no more than one storey, cover no more than 50% of each garden, extend into the garden no further than 50% of the depth of the house from the main rear wall, and be less than 1.5 times the house's footprint (Local Plan policy A5, 2017).
