Garden Rooms

High-quality, fully insulated garden rooms designed for everyday living.

Garden rooms are more than just an extra space, they’re an extension of how you live at home.

At CSL, we design and build bespoke garden rooms across Kent, tailored to your space, your needs and how you plan to use it. From initial design through to final build, every detail is considered to ensure long-term performance and everyday comfort.

Where To Use a Garden Room?

A garden room gives you the flexibility to create a space that works for you. From practical day-to-day use to more personal setups, the possibilities are wide.

What's the Difference?

We know, it’s a crowded market out there with many companies claiming to offer similar products.

Our Garden Rooms are fully-insulated, structurally-sound products which our expert team install. Meaning all year-round they can be used even in the evening and through the night.

We do not supply build-your-own solutions or lesser products disguised as a garden room. There are 3 main structures you can easily confuse when looking at the market; Garden Rooms, Summer Houses & Sheds.

CSL Construction - an amazing team

Chris and his amazing team constructed a huge decking area, covered pergola and bar in my garden. This was designed by Chris and everything I asked for was done and completed perfectly. Every member of the team was friendly and polite and they were always happy to answer my questions. I can highly recommend CSL Construction and I will definitely use them in future.
