Professional Home Installation – Included as Standard

From start to finish, we make the process effortless. Our expert installation service is included in the price of your building, so you can simply sit back and watch your new retreat take shape.

On the day, our skilled installers will arrive ready to build your garden room with precision and care. Once complete, they’ll leave everything spotless – so all that’s left for you to do is step inside and enjoy your beautiful new space.

Fully Insulated Design

This Insulated Garden Room is built with fully insulated walls, roof, and floor to ensure year-round comfort keeping the space warm in winter and cool in summer.

The Sherwood Range features 100mm thick walls which are double skinned with EcoQuilt insulation layered between the timber cladding. The same high-performance EcoQuilt insulation is also used in the roof. Made in the UK, EcoQuilt is a multi-foil insulation that incorporates an effective vapour control layer, protecting your garden room from damp and moisture.

For the floor, we use AirTec insulation, designed with a bubble structure that traps air, reducing heat loss by up to 50%.

EPDM Rubber Roof

Enhance the durability and weather resistance of your Mercia garden room with our high-quality EPDM roofing solutions. The building comes with EPDM roof covering as standard. Designed to provide superior protection, EPDM is a versatile and long-lasting material that ensures your timber structures remain secure against the elements. Its strong waterproof properties, combined with resistance to UV rays and temperature fluctuations, make it an ideal choice for outdoor use.

Customisable to Suit Your Style

Designed with flexibility in mind, The Sherwood garden room is available in a range of sizes and style, that can be tailored to suit your exact needs. Prefer extra windows for more natural light? Need an extra single or double door? No problem. Speak to our friendly team, we’ll work with you to create a layout that’s just right for you. Your perfect garden room, your way.

Garden Room Aftercare

The timber insulated garden room is supplied untreated. You must apply a preservative and waterproofing topcoat immediately after installation. Using the treatment after installation, followed by consistent annual treatment of the garden room, will maintain the high-quality finish and is a requirement of the 10-year anti-rot guarantee. A 1-year manufacturer's warranty is included as standard.

To treat the garden room, elbec recommends Protek wood treatment. Browse our Protek Royal Exterior Wood Finish Paint range to find the best paint colour to add your own personalised finish.  We have selected some of the best-selling Protek Royal Colours as an option on this page, as well as the highly recommended Protek Wood Preserver++

Does A Garden Room Require Planning Permission?

The garden building designs have been created to adhere to planning permission guidelines. However, we cannot guarantee that you will not need planning permission for a garden room.  We advise checking with your local authorities before constructing your garden buildings. 

What Garden Room Base Do I Need?

A flat, level solid base made of either concrete or concrete slabs is required for the installation of your Insulated Garden Room. You can purchase the Mercia Elite Timber Base With Ground Screws.  For more information on how to build a garden room base, you can contact us.

Prior to the Garden Room installation, be sure to check the base is level in all directions. If the base is not level, it will cause the building to twist and warp with the natural movement of the timber. It’s essential to adjust your base accordingly to achieve this before the installation process begins.

Delivery And Installation?

Since this building includes free professional installation, there’s hardly any effort required on your part!

You will need to ensure there is a 24” clearance all the way around the building and have the area cleared and ready on the day.  This will allow for the building to be assembled and for you to be able to treat the building.

Note: The installation team will not dismantle or remove any old buildings.

Once your order is placed, the manufacturer’s installation team will be in touch with a short pre-installation questionnaire. This helps us confirm that the site for your new Insulated Garden Room is ready, making sure everything runs smoothly on installation day.

After the foundation is set and access to your garden is clear, our installers will take care of the rest!

Your order is delivered on either a 3.5T, 7.5T or 18T Lorry.  You will be contacted within the delivery timescale and given a date for assembly.
