Permitted development · London & Hertfordshire
Does your house qualify for permitted development?
By Anderson & the LCCL Construction Team
Finchley N3 design & build, LABC award winners 2024 and 2026
Five quick questions, a straight answer: likely permitted development, prior approval or a planning application — and the fixed from-price. Most London lofts and single-storey extensions on houses outside conservation areas qualify. Start below.
The exceptions are flats and maisonettes, conservation areas, Article 4 areas and houses where permitted development rights were removed by an earlier consent. We check your address before the first drawing, and we obtain a Lawful Development Certificate as part of the design stage — it is the only document that proves the extension was lawful when you come to sell.
