Frequently Asked Questions

What kinds of extensions do you build?

We build all sorts of extensions, including single-storey and double-storey builds, depending on what space you need and how you want it to work.​ We work on both homes and commercial properties too, so we can tailor the finish and spec to suit the building and your goals.​

Can you help with planning permission?

Yes, we can point you in the right direction with planning permission and what you may need to get approved before work starts.​ If planning is needed, we’ll talk it through early on so you know what to expect and what the next steps look like.​

What should we think about before starting an extension?

A few things can affect what you can build like permitted development rules, how close you are to boundaries, and what’s allowed for bigger or two-storey extensions.​ If you share a wall with a neighbour, the Party Wall Act may apply too, and we can flag that during the first chat/site visit.​​

Do you take care of the whole project?

Yes, we aim to keep it simple and stress-free, from the first site visit right through to the final finish.​ We’ll agree what’s happening, when it’s happening, and make sure the build runs smoothly from start to completion.​

How do you keep it on time and on budget?

We turn up on the agreed start date, and we stick to the price we’ve agreed, so there are no nasty surprises.​ With over 30 years’ experience, we plan properly and focus on doing the job right, not rushing it.​

Are you accredited and insured for extension projects?

Yes. For every extension we build whether it’s a small side return or a full rear addition we’re fully insured and carry all the relevant industry accreditations. That means we follow recognised safety and quality standards, so you can feel confident your project is in good hands from start to finish.
