Start a free quote →Most integral garage conversions in Brent do not require planning permission — they're classed as an internal alteration, which is not development under the TCPA 1990. However, if the conversion materially alters the external appearance (new windows, raising the roof), planning permission may be required. Detached garage conversions to habitable use always need planning. Article 4 Directions in Brent may also affect eligibility. We confirm the planning route before quoting.
