Frequently Asked Questions

Do I need planning permission for a rear extension in Westerham?

Many rear extensions fall within permitted development limits, but projection depth, height, and boundary proximity must comply with national rules and any local restrictions.

Can I extend my house in a flood zone?

Extensions in flood risk areas may require additional assessments and possibly planning permission.

Can I build a wraparound extension without planning permission?

Wraparound extensions often exceed permitted development limits and usually require planning approval.

What is the 45-degree rule?

The 45-degree rule is a guideline used by some councils to assess impact on neighbouring properties, particularly in relation to light and outlook.

Can I extend a house that has already been extended?

Permitted development limits are cumulative, so previous extensions may reduce what is still allowed.

Can I build an outbuilding in my garden?

Outbuildings may be permitted development if they meet height, location, and usage restrictions.
