The Marie garden room uses hidden notch timber joints to create a clean contemporary design. The wood is delivered untreated, so you can tailor the colour or treatment to match the surroundings. Can be easily assembled with help over a couple of days!

Accessories to complete your new shed

Before ordering, take the time to browse our range of accessories so you can tailor your design with ease - such as cost-saving insulation or drainage systems to prevent damp. If you need advice or tips, please contact our expert customer service!

Where do I start?

Before you start assembling the kit, prepare a simple foundation. If you are planning to use foundation posts, use our post plan which you can find at the end of the manual. Once you have prepared the foundation, please follow our suggestion on how to place the concrete slabs or supports under the floor joists.

When the foundation is finished, you can start to assemble the garden room. As a first step, we suggest you familiarise yourself with the manual and check the parts in the kit. The timber sections are installed step-by-step according to the illustrations in the manual. In no time at all you will be ready to decorate your new Marie Garden Room

Garden Room Marie is developed by our own experienced designers - feel free to contact us if you have any questions about the product or assembly.

    Has been a fun DIY project. I hired a carpenter for 1 day to help build the house, the rest I did myself. The assembly instructions are not 100% complete as I have made some changes myself. The house will be used as a home office.
