Extensions – what we do

We’re experienced in building high-quality extensions for your home, property or commercial building. With an award or two under our belt, you know your extension project is safe in our expert hands. We pride ourselves on providing an excellent finish at a competitive price. 

Our projects are delivered with exceptional customer service and we’re happy to tailor our expertise to your bespoke building or home extension needs.

We offer a full range of extension services, including:

  • Conservatories
  • House extensions (single, double or even triple story)
  • Garden rooms
  • Porch extensions
  • Loft conversions
  • Kitchen extensions

It’s important to us that you understand every step of the project as it happens so that you know exactly what we’re doing and why. This is why we take the time to explain our processes in layman’s terms – none of this builder’s jargon. Not all companies take the time to do this, so we understand if you’re busy and would rather let us get on with the job.

We pride ourselves in providing a high-quality finish to our house extensions and the best service for our customers. Otherwise, they wouldn’t want to come back! Take a look at what they have to say about us in our review section.

Our company partners, Peter and Ross, are more than happy to speak to you about your project and what we might be able to do to support you. Maybe you’re confused about what bifold doors are? We can explain that to you in simple terms. Whether you’re looking for kitchen extension, conservatory, loft conversion or something else, our expertise is available to help – just contact us.
