Conversions in Croydon
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 Croydon, that covers Purley, Coulsdon, South Croydon, Addiscombe, Selsdon, Shirley, Thornton Heath, Sanderstead, Waddon. Croydon combines a dense town centre and tower-block skyline with substantial suburban housing across Purley, Coulsdon, Addiscombe and Shirley, plus the Victorian and Edwardian terraces closer to South Croydon and Thornton Heath. Its position on the A23/M23 corridor puts it within easy reach of our Surrey and Sussex teams, and it borders Sutton, Bromley and Reigate & Banstead.

Property styles in Croydon
Housing ranges from Victorian and Edwardian terraces near the town centre and South Croydon, through interwar semis across Addiscombe, Shirley and Thornton Heath, to larger detached houses in Purley, Coulsdon and Sanderstead. Loft conversions and rear extensions are common on the terraced and semi-detached stock, while the larger plots further south suit more substantial extension and outbuilding projects.
Planning considerations
Croydon Council (London Borough of Croydon) is the local planning authority. Several residential areas, including parts of South Croydon, Coulsdon and Addiscombe, are conservation areas, and parts of the borough's southern edge fall within the Metropolitan Green Belt, which affects extensions and new structures. As with all London boroughs, permitted development rights can also be more restricted on flats and some converted properties.

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.
