Why Surrey homeowners choose My Retreat

At My Retreat, we design and build bespoke garden rooms that feel like a natural extension of your home — not a temporary structure at the bottom of the garden. Every space is tailored to you: from the foundations up, the cladding, the doors and windows, the plastered interior and every fitting in between.

From the first phone call to the day we hand over the keys, you deal with one person: Kieron. No account managers, no lost handovers, no surprises on the invoice.

We serve homeowners across Surrey, Berkshire and Buckinghamshire — including Guildford, Woking, Weybridge, Cobham, Esher, Reigate, Redhill, Virginia Water, Windsor, Beaconsfield, Maidenhead, Bracknell and beyond.

Concrete pile or ground screw foundations

Plastic tubes filled with concrete driven 50–60cm in, or ground screws — both assessed per site. No full slab, no unnecessary disruption.

Structural steel floor frame

The feature that genuinely sets us apart. A fabricated steel frame — not timber — that will never rot, bow or fail under load.

Plastered interiors as standard

A full skim-plaster finish — exactly like the interior walls of your home.

No hidden extras

Foundations, electrics, heating, flooring and lighting are all in the quote.

 Trustindex verifies that the original source of the review is Google. We’re absolutely thrilled with our new garden room and hidden shed from My Retreat Garden Rooms. The quality is fantastic, and the whole experience was just as impressive. Kieron and the team were brilliant—professional, friendly, and a pleasure to have around. James, Gustav, and the rest of the crew worked with real care, and everything ran smoothly from start to finish. The finished space has genuinely transformed our home, giving us the extra room we needed and a beautifully integrated shed. A huge thank you to everyone involved. We couldn’t be happier.

 Trustindex verifies that the original source of the review is Google. Kieron and the team did a great job of installing our garden room which we've used as a summer room and gym for several years now, it's been used loads and I really love making use of the gym.  The building still looks new after 4 years usage, other than some expected plaster cracks. The inside and outside finish has been great so really happy with the end product. We did "up spec" a number of areas to make sure we got what we wanted such as a roof design adjustment, highest spec doors/bi folds, larger air con and Millboard cladding and decking which has a fantastic natural looking finish. We also worked closely with the install team to make sure we got exactly what we wanted, but they were reactive to everything requested so that was good. To make the most of the space we installed a Speediance GM2 cable machine which is incredibly space efficient and covers loads of exercise options, so great kit for a small space.

Best in the business following our comprehensive research and now first hand experience, all of our friends and family have requested their details after seeing our build, so book while they're still available! Thanks again Update 3 years after installation: just wanted to add to this review to say that our garden room continues to give us joy and that the novelty has not worn off. A huge thank you to the team for their availability for further modifications and aftercare, 10/10 service!!!

 Trustindex verifies that the original source of the review is Google. Kieron was very proactive right from the start with helpful ideas on planning the garden room. The site team were very competent and the build was complete within 3 weeks. Very happy with our garden room, sauna and hot tub and strongly recommend anyone to use My Retreat Garden Rooms.

Common Questions

Garden room FAQs — Surrey & the Home Counties

How much does a garden room cost in Surrey?

Fully insulated garden rooms from My Retreat start from £18,376 installed including VAT. Final cost depends on size, cladding, door and window specification, and any extras such as a bathroom or air conditioning. We provide fully itemised quotes — no surprises. Use our 3D tool for an instant estimate.

Do I need planning permission for a garden room in Surrey?

Most garden rooms fall under Permitted Development and don’t need planning permission. Exceptions include conservation areas, listed buildings and rooms used as separate living accommodation. Planning responsibility is yours as the homeowner — we can refer you to a trusted architect who can advise for a fee.

Can I use a garden room all year round?

Yes — if it is built properly. All My Retreat rooms include fully insulated walls, floors and roofs, a structural steel floor frame, double-glazed UPVC windows and heating as standard. They are comfortable year-round as home offices, gyms, studios or additional living space.

How long does it take to build a garden room?

From deposit to installation is typically 4–5 weeks. On-site, the build takes 2–3 weeks. Additional time may be needed for bathrooms or landscaping. We confirm a clear timeline before any work begins and Kieron personally oversees every project.

What foundations do you use?

Concrete pile foundations — plastic tubes filled with concrete, driven 50–60cm into the ground. Stable, clean, and avoids the disruption and cost of a full concrete slab. We assess every site individually before confirming the approach.

Do garden rooms add value to your home?

In most cases, yes. A fully insulated, properly built garden room increases usable square footage, adds buyer appeal and is increasingly recognised by estate agents as a premium feature — especially across Surrey and the Home Counties.
