About IDM Garden Rooms
Your Garden. Your Space. Your Rules.

IDM Garden Rooms has been building bespoke timber frame garden rooms across Clacton, Frinton, Walton-on-the-Naze and the Tendring district, with years of trade experience behind every build.

Every garden room is designed and built around how you actually want to use it — not a flat-pack kit, not a catalogue product. We handle everything from initial design through to the finished build. One call covers your whole project.

Most garden rooms fall under permitted development — meaning no planning permission required. We'll confirm this for your specific property as part of your free site survey.

What We Build
Six Ways to Use Your Garden Room
Every garden room IDM builds is bespoke — designed around how you want to live, work and relax.
💻
Garden Office

A proper workspace away from the house. Insulated, wired and comfortable all year round. The most popular choice for Essex homeowners working from home.

🏋️
Home Gym

No gym membership, no commute. A dedicated fitness space built to handle the weight — reinforced flooring, ventilation and power included.

🎮
Games Room

A space for the family that keeps the noise out of the house. Pool tables, gaming setups, cinema screens — we build around your vision.

🛋️
Extra Living Space

A lounge, a reading room, a quiet retreat. An extension of your home without the cost and disruption of a full building extension.

🎨
Art Studio & Hobbies

Natural light, space to spread out and no interruptions. Ideal for art, music, crafts or whatever needs its own room in your life.

🍸
Bar & Entertainment

Your own pub at the bottom of the garden. We've built some incredible entertainment spaces across Tendring — ask to see the full portfolio.
