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.

What our customers say

Consistently rated 5 stars. Real reviews from homeowners across Surrey and the Home Counties.

★★★★★

"What can we say? We are over the moon with our new room which we are using as a gym. It was important for us to go with someone we felt we could trust and put us at ease. Kieron is professional, honest and just a really lovely guy so it was an easy choice. From our initial meeting he really listened, through the design and tweaking to support what we wanted. His whole project management was flawless, ensuring everything went as smoothly as possible. The build and installation guys were utterly brilliant working in awful weather but ensuring perfection. We can't thank you enough, we love it."

Nicky Usher
★★★★★

"Huge thank you to the My Retreat Garden Rooms team for a speedy, timely, professional, top quality and customised garden room. 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. 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."

Dipesh Patel
★★★★★

"Great experience with Kieron and the team. He really helped us build the vision at our clinic. He was the only one who actually came out to meet me in person and to really get what I wanted to be done, which is why I went with him in the first place. Seamless process. Everything was very easy from start to finish. Would highly recommend, especially if you're like us where we had a quite a weirdly shaped design to fit our back area. Building looks great too."

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.
