A Thicketts garden room is a fully insulated, year-round room at the bottom of your garden: an office, gym, studio or quiet escape, architect-designed and built by our own Poole team.
We build insulated garden rooms right across Dorset, with fixed prices and no planning permission needed on almost every project.
Every certificate we hold is one you can check yourself. We’ll hand you the paperwork at completion without being asked.
“Every member of the Thicketts team was meticulous, professional and a pleasure to work with. They turned our vision into something truly special.”

Let’s get started
Either our team will call you back to discuss the details or a project manager will pay you a visit - you choose!
Lovely finishes as standard.
We design our rooms to feel as good as they look: engineered oak flooring, painted walls, track lighting, double glazing and a low-maintenance roof. A proper room, built for year-round enjoyment.
Built warm, built to last.
Fully insulated walls, floor and roof, argon-filled double glazing and a low-maintenance roof mean your garden room is genuinely usable every day of the year, not just in summer. Built to the same standard we’d build for our own families.
What’s included?
This is no garden shed. Every Thicketts room is designed for year-round comfort, built with premium, sustainable materials, and finished so it feels like a room inside your home. All included in one turnkey package:

One local team, start to finish
Design, groundwork, build and electrics are all handled by our own Poole-based team. No subcontractor roulette, and one project manager who knows your name.
No planning permission, no fuss
Almost all of our rooms fall under permitted development. We handle the checks for you, and most builds are finished within two weeks on site.
Designed around you.
No two gardens, or families, are the same, so nothing here is off-the-shelf. Choose your size, layout, cladding, doors and colours with our designer, and we’ll shape the room around exactly how you’ll use it.
