Add value

We all want to make the most of the property we have – adding value is a better option than moving house. There may be more options than you realise, and if you have a basement this can be an excellent way to improve your living space and increase the value of your home. It doesn’t matter what condition the basement is currently in; it’s our job to make sure it is safe, usable and is adding as much value for you as possible. You can dig down further, lower the basement, even dig out a basement from scratch… As soon as you have the correct planning permission, we can make it happen.

As experienced renovation specialists, we are the ideal team to carry out your basement conversion. We will be able to work with your existing plans, transforming your basement space into an integral part of your home. With basements, you can never quite be sure what you will find, so you need an experienced team to work around any issues. We can be that experienced team – we have helped many homeowners before you to create newly refurbished basement rooms as well as entire basement flats, and we want to do the same for you.

A bespoke basement

Basement conversions are completely unique. We work to specific designs to ensure each basement we convert will give you exactly what you want from it.

  • We work closely to architectural plans.
    Simply provide us with your plans and we will work to them, ensuring your basement conversion meets (or exceeds) your expectations.
  • We can recommend an architect if needed.
    If you are still in the planning process, we are happy to recommend the skilled, professional architects we work alongside.
  • Full structural work ahead of your project.
    Basements need to be reinforced and stabilised. We dig down and underpin the basement to make sure it is structurally sound.
  • A high-end, premium aesthetic finish.
    We never compromise on aesthetics – as specialists in premium property services, we ensure work is finished to the highest standards.
  • An expert, highly reliable service.
    We have completed many high-standard basement conversions and can do the same for you, working closely to your plans.
  • Free consultations and full quotations.
    Written quotations are emailed to you following an on-site consultation, so we can be completely accurate.
