Frequently Asked Questions

Do I need structural calculations?

Yes, building regulations often require structural calculations for beams, foundations, and load-bearing elements.

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 right up to my boundary?

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

Does permitted development apply to HMOs?

Some permitted development rights may be restricted depending on property use class.

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.

Can I extend a listed building?

Listed buildings require listed building consent, even for minor works. Permitted development rights typically do not apply.
