Extensions

Extensions in Falmouth

Much of Falmouth is made up of older terraced and Victorian houses, many of them on steep roads close to the water. We carry out single and two-storey extensions in Falmouth, keeping the groundwork, structural work and finishing within our own team.

Homes in Falmouth

In a harbour town where so many homes are older terraces or Victorian houses, the starting point is finding out what you are allowed to build. If your house is listed, you will need listed building consent; if it is in a conservation area, permitted development covers less. Where neither applies, plenty of single-storey rear extensions fall within permitted development size limits and go ahead without a full planning application. A steep street adds its own consideration, because the groundwork and foundations must suit the plot, and building control then checks them, along with structure, insulation and drainage, against the Building Regulations.

“Miles and Marc carried out an extension at our home in Falmouth. We are so happy we chose them to carry out the building works. From start to finish there work has been top class, there communication is great and the project was finished in brilliant time. If you are planning any building works, we couldn't recommend them enough!”

What matters for extensions in Falmouth

We run extensions in Falmouth in a set order, with the same in-house team responsible throughout. The ground is prepared and the foundations go in, the structural work follows to create the new room, and the finishing makes it ready to use. If you would like a price, describe the space you want, tell us about the house as it stands and pass on any drawings or photos.

  • Foundations dug and laid once the ground is prepared
  • The structural shell put up for a single or two-storey addition
  • Insulation and drainage installed to meet the Building Regulations
  • Finishing completed in-house, so the job ends with the team who started it

Questions about extensions in Falmouth

Have you built an extension in Falmouth before?

Yes. The review on this page comes from a homeowner whose extension we built in Falmouth. They praised our communication, the standard of the work and how quickly the project was finished.

Will I be dealing with several different firms during the build?

No. We manage the whole extension in-house, from the groundwork and structural work through to the finishing, so the same team stays with your project.

What does building control check on an extension?

Building control looks at the foundations, the structure, the insulation and the drainage, making sure each meets the Building Regulations. We plan the groundwork and the build with those checks in mind.
