Frequently Asked Questions

Can I build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

Can I convert my garage into living space?

Garage conversions are often permitted development, but planning restrictions may apply depending on conditions attached to the original approval.

How is the original house defined for measurement purposes?

The “original house” refers to the property as it stood on 1 July 1948 or when it was first built, not including later extensions.

What measurements are used for height?

Height is typically measured from the highest ground level adjacent to the building.

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

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

Are there restrictions on side-facing windows?

Yes. Upper-floor side-facing windows typically must be obscure-glazed and non-opening below a certain height.
