About Us

Irwin has been actively involved in construction and development within the Cambridgeshire region for nearly fifty years, operating up until July 2024 under our previous identity, David Reed Homes Ltd.

Selecting a builder for constructing a new home, extending your current one, or embarking on a renovation project is undoubtedly one of the most important decisions you will make. We know that you should never compromise on your home, and that’s why we, in turn, will never accept anything but the best at every stage of every one of our developments.


We pride ourselves on being an approachable business committed to providing first-class building and development services for a range of ever-discerning customers. Our versatility and attention to detail have enabled us to create many bespoke renovations, extensions, luxury homes and apartments, – with a level of friendliness and after-sales care that you’ll cherish as much as the product we provide.

At Irwin, our expertise extends beyond traditional construction. From extensions and renovations to the creation of garden rooms or elegant oak orangeries, we're equipped to bring your vision to life.


Whether you're seeking a new home, to expand your living space or to revitalise your home, we have the skill and craftsmanship to make it happen.  No job is too small for us.

Our History

David Reed Homes Logo

Established nearly 50 years ago, by founder David Reed, the company grew from humble beginnings and continued to build on its solid reputation through the years for high quality construction within the Cambridgeshire area.


With core values still deep rooted within the company an opportunity for new direction presented itself, and with that, our new name of Irwin Building and Development was born. We remain driven by the same passion for delivering our clients' dream homes through quality craftsmanship and meticulous attention to detail.


Managing Director Nick Rust and Construction Director Tim Bryant are excited to take the company forward with energy and focus to provide an uncompromising service to our clients.


What people say about Irwin...

"We moved into our new home just over 2 years ago and we have been thrilled with the product. The attention to detail has been so impressive and the care & after sale have given us great comfort in knowing that we could always contact them with any questions about the property and expect a swift, helpful reply. Thoroughly recommend!"
