Conversions in Bromley
A property conversion changes the use of existing space — such as a loft, garage, barn or outbuilding — into new habitable accommodation, and typically involves structural alterations, insulation upgrades, new services, and Building Regulations approval, with planning permission or listed building consent needed in some cases.
In Bromley, that covers Beckenham, Orpington, West Wickham, Chislehurst, Petts Wood, Hayes, Bickley. Bromley is one of the greenest London boroughs, with a historic High Street and residential areas ranging from Beckenham and Orpington's Victorian and interwar housing to the more rural character around Chislehurst and Hayes, close to the Kent border and within easy reach of our Sevenoaks and Tunbridge Wells teams.

Property styles in Bromley
Bromley's housing stock includes Victorian and Edwardian terraces and villas near the town centre and in Beckenham, substantial interwar detached and semi-detached houses across Orpington, Petts Wood and Bickley, and larger period properties around Chislehurst and Hayes, many on generous plots suited to rear and double-storey extensions.
Planning considerations
Bromley Council (London Borough of Bromley) is the local planning authority. Chislehurst and parts of Beckenham and Hayes are conservation areas, and much of the borough's southern and eastern edge is designated Metropolitan Green Belt, which restricts new buildings and substantial additions beyond normal permitted development limits.

Do I need planning permission for a loft conversion?
Many loft conversions fall under permitted development if they stay within volume limits and do not extend beyond the roof plane at the front. Dormers, roof terraces, and conversions on designated land or flats usually need planning permission. We confirm this at feasibility stage.
What head height do I need for a loft conversion?
As a general guide, a minimum ridge height of around 2.2 to 2.3 metres is usually needed for a workable staircase and standing space, though this varies with roof pitch and layout. We measure this on survey before advising on feasibility.
