FAQs

Extensions in Aspley Guise: your questions

Can’t see your question? Call us on 01480 272 600 or send us a message.

Do you build house extensions in Aspley Guise?

Yes. Tier One Developments designs and builds single storey, double storey, side return, wraparound and kitchen extensions in Aspley Guise, plus loft and garage conversions. We’re based at Wyboston Lakes, about 18 miles away.

Do I need planning permission to extend my house in Aspley Guise?

Not always. Many single storey rear extensions can be built under permitted development (up to 3m deep for semi-detached and terraced houses, or 4m for detached). Larger and two storey extensions usually need permission from Central Bedfordshire Council. Parts of Aspley Guise are in a conservation area, where permitted development rights are reduced, so permission is needed more often. We check this at the first visit.

How long does an extension take in Aspley Guise?

Allow time for design and approvals first: householder planning applications are usually decided within about eight weeks. Most single storey extensions then take a few months on site. We give you a realistic programme with your quote.

Can you handle the drawings and planning for my Aspley Guise extension?

Yes. We provide the design, planning or lawful development certificate application, building regulations drawings, structural calculations and Party Wall notices where needed, then build the extension, all as one team.

Will an extension add value to my home in Aspley Guise?

A well-designed extension usually adds useful space and value, especially extra bedrooms, bathrooms and open-plan kitchens. It is also often cheaper than moving once you account for stamp duty, fees and removals.
