In a matter of days, you can have a fully built and ready-to-use annexe on your property. But our commitment doesn’t end with construction.

We believe in providing exceptional customer service and managing every aspect of your annexe project with our team of architects, project managers and contractors.

Our comprehensive approach covers everything from design to groundworks, electrics, and plumbing if required.

We even take care of clearing and preparing the site, ensuring a hassle-free experience for you.

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.”

Revolutionising Annexe Construction

 At Hawksbeck, we are proud pioneers in the annexe construction industry, revolutionising the way garden annexes are built. We have set a new standard by utilising structurally insulated panels (SIPs) to create a far superior product compared to standard builders.

SIPs are composed of an insulating foam core sandwiched between two robust structural facings. This ground-breaking construction method results in garden annexes that are 7 times stronger than timber frame structures and 3 times stronger than traditional brick buildings.

While builders typically rely on conventional methods, we embrace innovative technology to ensure strength and durability. 

At Hawksbeck, we go above and beyond by surpassing UK Building Regulation Standards with our garden annexes. If desired, we can even coordinate with building inspectors on your behalf to ensure that your annexe achieves the necessary approvals, giving you complete peace of mind.

Every structural aspect of a Hawksbeck garden annexe has received BBA approval. Our Structurally Insulated Panel System (SIPS), including the walls, floor, and roof, proudly holds certification from the BBA.

Furthermore, our foundations and plasterboard have also earned BBA approval, attesting to the rigorous testing our materials undergo to meet the highest standards.
