Do I need planning permission for a loft conversion in Barking and Dagenham?
Usually not for a house, if the loft stays within permitted development limits. On a terraced house, that means no more than 40 m³ of extra roof space, a dormer that does not sit on the roof slope facing the road, materials similar to the existing roof, and side windows that are obscure-glazed and fixed shut below 1.7 m. A rear dormer on a Barking terrace often fits; a front dormer or mansard usually needs an application. Roof work on a block of flats needs both planning permission and the freeholder's agreement.
