Our extensions need to stand the test of time, so it's very important to us that we produce work we're proud of.

Get the home extension you've always longed for

Duncan Thompson offers a complete home extension service from architectural design, obtaining all the necessary permits and approvals, to final construction and completion of the extension. You will have an accurate quote and concept designs within weeks of the first meeting. This is before you've even made any commitment to final plans and approvals.

We're extremely passionate and focussed on seeing you and your family in the home you've always wished for. We will work with you to uncover the requirements and desires your family has for your new home. Every detail is carefully considered during the initial design phase, ensuring the final design is the best outcome for your family.

The highest quality house extensions

Designing and building great home extensions is our passion. We love great design and will never underestimate the need to meet deadlines, but the overall quality is what matters most to us. Our commitment to achieving a quality extension for our clients is unmatched within the industry, and this is always evident when the final inspection is conducted with the family.

It is our job to provide you with the best possible home extension that we can, that's why we employ experienced and skilled industry professionals from the design stage, right through to the completion of construction. Our reputation has taken time to build, so it is important that we protect it by providing you with the best quality extension possible.

We appreciate all of your efforts during our extension periods and would be happy to refer our friends to Duncan Thompson Extensions, which we have done twice already!
