  • Can my house be extended?

     It might come as a surprise for you but the good news is that about 90% of traditional houses can be converted. The first step is a survey in situ carried by our professional team.

  • I’m afraid my house is too small.

    If you want to proceed with an extension project there are some specific measurements that need to be taken.  If you meet the requirements, and most people do, you are on a right path to create the house of your dreams!

    Our team is capable of transforming even a small house into a beautiful space thanks to our creativity, imagination and thoughtful use of dormer windows and staircase positioning.

  • How much will it cost?

    We can offer you a professional, fully detailed and free of charge loft conversion quote after carrying a survey of your house. Get in touch – it costs nothing!

  • How long will the work take?

    It is said that for an average sized home we wound usually complete the work in a few weeks. We could provide you with a more detailed timing after carrying an initial survey.
