Croydon's diverse housing stock presents unique opportunities for garden annexes. From the generous plots in Shirley to compact spaces near East Croydon station, each project requires careful consideration of access routes and neighbour relationships. Local planning officers appreciate well-designed proposals that complement the existing streetscape, particularly in conservation areas around Croham Hurst.
Modern annexe construction utilises SIPs panels and timber frames, creating thermally efficient spaces within weeks rather than months. Ground screws eliminate the need for deep foundations - crucial when dealing with London clay soil common across CR2. Smart positioning maximises natural light whilst maintaining privacy from neighbouring properties, essential given typical boundary distances in Waddon and Selhurst.
Having navigated hundreds of planning applications through Croydon Council since 2008, relationships with local building control matter. Every annexe meets current building regulations, from insulation standards to electrical safety certificates.

Most properties allow straightforward connections via armoured cables and water pipes run alongside existing paths. Drainage often links to existing inspection chambers, though some older Victorian properties near South Croydon require careful route planning to avoid original soakaways.
