Retrospective application for a rear roof extension at 15 Balham High Road

ImpactAutomated estimate

Summary

The owner has applied to keep a rear roof extension that has already been built at 15 Balham High Road. Because the work was done without permission first, the owner is now asking the council to approve it after the fact. The property is on a busy road in Balham, close to several schools including Alderbrook Primary School a couple of minutes' walk away, and La Retraite Roman Catholic Girls School a few minutes' walk away. The area around the property is largely shielded by other buildings, with only a small number of nearby homes having a direct view of the site. The application is for a single roof-level change at the rear of the property. Because it is retrospective, the council will assess whether it meets planning rules as if it had been applied for before work started.

What you can do

You can comment on this application through Wandsworth Council's planning portal using reference 2026/1070. The council can consider how the extension affects the appearance of the building and the street. They cannot consider personal matters such as the applicant's behaviour or the fact that it was built without permission first — only whether it is acceptable in planning terms.
