Homes in London

Much of London’s housing is Victorian and Edwardian terraces, which is why side return extensions, rear dormers and mansards are so common. Many streets are in conservation areas, and several boroughs use Article 4 directions that remove some permitted development rights.

What goes into a wraparound extension?

Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.

How is a wraparound extension approved in South Croydon?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development. Most need householder planning permission, which usually takes around eight weeks once validated.

What should I think about before starting?

The corner steel connection is the critical detail and is designed by a structural engineer.
Both neighbours may need party wall notices.
