Bespoke Luxury Garden Annexes From Hawksbeck Annexes

Welcome to Hawksbeck Annexes, where we take pride in crafting beautiful and bespoke garden annexes that are built for life.

Our team of architects, designers and engineers have spent years researching and perfecting the construction of our garden annexes, ensuring that we provide you with unparalleled quality and longevity.

At Hawksbeck Annexes, we use a revolutionary material called SIP’s (Structurally Insulated Panels) to construct every one of our garden annexes.

More robust than traditional building methods, our SIP’s panels are also better insulated, making our annexes safe and habitable spaces.

Our annexes can also be ordered and constructed with short lead and installation times, gaining you more precious time to spend on you and your family.

James & Emily

“We are delighted with our garden room, which we intend to use as guest accommodation and to let through AirBNB. It is finished to an incredibly high standard, and we were so impressed with Jon and his team.”

“Jon’s diligence and thoroughness reassured us throughout the project, and the end product is of better quality and at a lower cost than the pre-fabricated garden room options.”


“From the very beginning, Hawksbeck have been fantastic. Our project required the use of all their services and all teams were highly skilled, friendly and professional. Whenever we had a question, there was always someone available straight away to help.”

“We love our new garden room, not only has it transformed our garden but has also given us more living space in the house. We would thoroughly recommend using Hawksbeck to anyone.”

Nik & Rita

“Our project with Hawksbeck was a journey that began over 2 years ago, and Jon and the team were there with us throughout. We had many Garden Building companies come out to see us, but none of them offered the same service that Hawksbeck provide, making them unique.”

“If you are after a team that manage the project for you from the start (where it is just an idea, the planning applications and the design iterations) to the completion (an amazing usable, quality and robust build) then look no further.”
