Looking for a Trusted, Local Builder in Richmond?


If you’re looking for builders who are local, trusted and reliable, then look no further. We offer our customers a great team who will guarantee quality builds to the highest degree. We have racked up many years of experience as local builders in Richmond TW9, TW10, and beyond. We keep close contact with our clients to make sure we are on track with their design ideas. We also benefit from longstanding relationships with selected suppliers and specialists to help with every stage of the build.


When looking at your property for possible home extension, we will assess your Richmond home and see if it is suitable for the building project. Here, we will look at your budget, the area, neighbours’ houses and a timetable. We hope to help you to add value to your existing property, and will look at whether there are any planning restrictions, whether your neighbours are happy for you to proceed, and set a deadline for your extension to be complete. We will talk through the wide-ranging options that exist for house extensions and help you in any areas we can advise you in, such as gaining planning permission.

Loft Conversions

We provide expert loft conversion services throughout Richmond, whether you’re looking to extend a bungalow, or add and attic conversion. It is one of the easiest ways to gain extra space and provide you with extra value should you wish to sell in future. We will determine whether your Richmond loft is appropriate for a conversion project by looking at various factors, such as head height, pitch angle, any obstacles, the age of the structure and the end shape (whether gable/straight, or hipped/angled). We provide a bespoke service to our customers, so we are confident we will be able to help you move towards your ideal home with your loft conversion.
