The Full Turn-Key Granny Annexe Service
…and we’re here to help
Deciding upon your own Garden Annexe can be a daunting exercise, and we understand how complicated it may appear. So, from the outset we offer impartial and friendly advice which is focussed around your requirements.
In our own UK office and factory, we design, manufacture and install a personalised garden annex every week. Ours is a full “turn-key” service whereby we complete every aspect of the annexe service, including providing the concrete base, the services, trenching and all the connections. We also undertake all the Planning Permission or Certification requirements that your annexe may require.
But first, once you’ve reviewed our brochures, we’ll visit you to survey your garden and we’ll prepare a suggested layout so you can visualise the space and location that your annexe will enjoy. We’ll assess your site for location, access and the availability of services and we will provide you with a full fixed-price quotation for the full service for the supply of your Garden Annexe.
Then, once we’ve gained the correct planning permission or certification, on your behalf, for the garden annexe in garden we’ll complete the Site Pack (all the necessary preliminary groundwork) which takes about 1 to 2 weeks. We then manufacture each garden home using CADCAM precision cutting equipment so every component is finished to 0.1mm accuracy. This means the assembly of the annexe by our own team is rapid and professional.
The final commissioning of every garden annexe is completed by our own plumbers and electricians who complete the ultimate connections. Finally, we implement the decoration so we handover a beautiful pristine new home to you.
Normally, we complete each project within 6-7 months from the date of your order, (including 3 months for the necessary documentation) but we are typically “on-site” in each location for only approximately 4-5 weeks.
We take our Customer Service seriously too - so you have you a dedicated contact in our office, who will manage your enquiry and then be your regular point of contact throughout the process.
We look forward to being of service - so please do call us on 0800 368 9781, drop us a line here, or click here to request a brochure.

Consistent 5 Star Reviews
“Enormously Impressed”
Neil:
We were enormously impressed with the design, construction and installation process from start to finish.Everyone who worked on the project was diligent, respectful, thoughtful, friendly, hard-working and meticulous, and every query we had was dealt with quickly and efficiently.
The building itself is absolutely perfect for our needs – I wouldn’t hesitate to recommend Garden Annexes.
“I cannot praise this company enough”

I cannot praise this company enough they are outstanding. High quality workmanship. Professional team of workers so helpful and kept me in touch with progress. Thank you so much for providing my perfect little end of garden home.

“Just phenomenal”
Emily:
The whole team at Garden Annexe are just phenomenal - from day one we were cared for, supported and they understand how stressful the whole process is when you are caring for a relative who is unwell and making significant life changing decisions.
The quality of their service is unparalleled - from quick responses to minor queries, to guiding you through the whole process, the whole team are brilliant.
The build process was efficient and quality and after care is so responsive. We are absolutely delighted with our annexe, and I would highly recommend the GA team - you wont find better
“I couldn’t be happier with our experience”
Monica :
We couldn’t be happier with our experience with Garden Annexes. Right from the start, everyone we dealt with was patient, considerate, and genuinely caring, which made such a difference with a decision of this size.
For us, this wasn’t just a building project. It was about moving my mum from our 3-bed family home of almost 50 years into a 1-bed annexe in my sister’s garden. This was a huge step, and we really appreciated the time and understanding we were given. Lauryn, who guided us through the design stage, was amazing. She knew how big a change this was for us, gave us space to talk things through (and even change our minds a few times!), and never made us feel rushed.
