Fully Insulated

Fully Insulated

Our high-performance multi-foil insulation is pre-lined on the wall, floor, and roof panels of your Evolution Cedar building. This provides fully insulated panels that trap air inside the cavities, while the multifoil insulation creates an insulated barrier that keeps the temperature locked in. This means you can enjoy your building all year thanks to our double-glazed uPVC windows and doors which keeps your building warm in the winter and cool in the summer.

Hand Crafted

Our Evolution Cedar with an apex roof is hand-built by our expert production team, who hand-pick the best quality materials to ensure that your building is of the highest quality. Manufactured in our facility on the cusp of Sherwood forest, our skilled team build your building to order and with their expertise and experience, you can be assured that your building will withstand the test of time.

Team Hard Work

We do the hard work for you

The Evolution Cedar Garden Room is designed to be as simple to put together as possible, whilst giving you the option to tailor it to your requirements. We pre-line every panel with our multifoil insulation so you don’t have to, making your building go together faster and easier. Designed with you in mind, if you plan to install your own electrics in the building, the internal wall cladding is added after the building is assembled to save time during installation. The wall battens are also fixed in place for you, to make adding the internal cladding even easier.

The Perfect Garden Office

The Evolution Cedar Garden Room is an ideal garden office where you can work in peace and quiet, away from the distractions of your home. You can be sure that your building will be a quiet place to work thanks to its sound-reducing Western Red Cedar external cladding, double-glazed windows and doors, and an 80mm thick wall panel construction. You can also use your building all year long, regardless of the season, and remain at a comfortable temperature.

If you have heavier items to store inside, such as large desks and storage units, you can tailor your building to have a thicker floor, and you can assemble your building with the partition on either side depending on your requirements.

UPVC Windows and Doors as Standard

Our uPVC windows and doors come as standard to provide increased security and u-values to your building. Because the uPVC windows and doors are double glazed, you can rest assured that they will keep your building completely insulated and secure your belongings with a deadlock on the uPVC doors and opening window. The glazing is 4mm thick toughened glass with a 20mm spacer, giving it a total thickness of 28mm. You can also choose the colour of your uPVC which is either white, light oak or graphite.

Easy self assembly

Assembling a garden building yourself may seem like a difficult task, however, due to the modular design of our buildings, assembling them couldn’t be easier. We provide simple stage by stage assembly instructions and all of the fittings and fixings required.

Whether your building is large or small, each building size is made from the same parts and so a larger building is no more complicated than a smaller size because they will fit together in the same way and in the same stages.

The modular panels are also able to fit through a standard house door so you can transport any size building through your house onto the build area. It is recommended that two people assemble the building due to the weight of the panels. It is also critical that the building is assembled on a solid level base to comply with the warranty, to ensure that the building is assembled correctly and to ensure there are no problems with your building after installation.
