The low maintenance way to extend your home

Garden buildings have long been a popular choice amongst homeowners looking to create more living space, without the hassle or expense of building an extension or loft conversion.

But if you’re seeking something that is high quality and also weatherproof, low maintenance and keeps you warm the whole year round, then it’s time to look at the many benefits of composite garden rooms from Surrey Hills Garden Buildings.

Composite is made from multiple materials, providing excellent strength and durability, as well as a pleasing aesthetic. Inside you’ll find insulating materials as well as many other layers, all protected by a weather resistant outer skin.

The beauty of choice

A composite clad garden room from Surrey Hills will afford you a great deal of choice when it comes to features and styles. And with every building made to order, you’ll be able to truly make it your own.

Everything from flooring and doors and windows to pitched roof tiles and the composite cladding itself offers ample variety, allowing you to perfectly tailor your garden room to suit your personal taste and to blend in seamlessly with your existing outdoor décor.

Added extras, such as opening roof windows or fixed glass panels to let the light stream in throughout your outdoor room, and the likes of full height, pocket, and corner return windows all allow you to take your personalisation options even further.

Winter warm garden buildings

Thermal performance stands for everything when you live in a climate as changeable as ours here in the UK. Composite garden rooms offer the benefit of low-maintenance weatherproofing, which means you won’t need to treat them regularly to protect them from the elements as you would with timber buildings.

The Surrey Hills range of composite summer houses, garden offices and leisure rooms offers top thermal performance courtesy of multi-layer insulation that allows the buildings to retain heat during the winter, as well as keeping cool during the summer. The base is also fully insulated to further improve the overall thermal performance of your composite garden room.

The EPDM synthetic rubber flat roof covering offers excellent weather and heat resistance too, and the uPVC windows and doors are all double glazed for added protection. For pitched roof composite garden buildings, there’s a choice of tiles, all of which come with a 40-year manufacturer’s weatherproof guarantee.

Composite Garden Rooms - Frequently Asked Questions

Which of your garden buildings can be composite clad?

Our entire range of bespoke, made to order garden buildings can be ordered with either composite cladding or timber cladding.

This includes garden offices, garden gyms and therapy rooms, lifestyle and leisure rooms, summer houses and combination rooms.

Do I need planning permission for a composite garden office?

In most cases, you won’t need planning permission for a garden building. Under Permitted Development Rights, you are allowed to construct a garden room as long as it does not exceed more than 50% of the original garden space.

The room must have a maximum eaves height of 2.5 metres, with an overall height of 3 metres for a single pitched roof, or 4 metres overall height for a dual-pitched roof.

Other criteria apply, and you can find out more in our guide, Do You Need Planning Permission for a Summer House or Garden Room?

Can I customise my composite clad garden room?

Yes, it is completely possible to customise any of our composite garden buildings to suit your individual needs. From windows and doors to roof tiles, fascias, soffits and brick borders, there is a great deal of choice to be enjoyed. You can even choose a cladding that will complement the colours of your garden or home exterior.

Will it be warm inside my composite garden office?

Yes, you can rest assured that even during the winter, you will be able to work comfortably in your composite garden office. Thanks to the high performing multi-layer insulation, your building will retain heat during the winter, and stay cool during the summer.

Are there any care instructions for a composite clad garden room?

Composite cladding is naturally low maintenance and comes with the reassurance of ongoing performance without the need for any sort of treatment. However, weather does have a habit of leaving residue on the surface of the building, so you will need to take some simple steps to keep it clean so that it continues to look as new.

A good guide is to carry out a routine clean every six months to clear away any surface dust and dirt that has accumulated on the boards. Warm, soapy water applied with a soft bristled brush or sponge is perfectly sufficient for a surface clean.

For a deeper clean, you can opt for a jet wash, but do proceed with caution. Be sure to use a low power setting, and avoid getting any closer than 25cm.

For any stubborn stains, try to treat the area within the first seven days of the stain appearing. If you can’t remove the stain using the routine cleaning methods as outlined above, a water-based cladding cleaner designed specifically for purpose may do the job.

Do composite garden buildings need a base?

It is vital that a base and foundations are correctly prepared for all composite garden rooms. Failure to provide a suitable base could affect the operating of the doors and any opening windows.

Our experts recommend the base is the minimum size for the individual building ordered and, to ensure the stability of your garden room, the base must be firm and level.

Can you remove an existing garden building or shed from my garden to make space for my new composite clad garden room?

We have our own in-house team of base installers who are also able to remove or relocate any existing garden buildings to prepare the site for your new composite garden room.

During our site visit we will assess what needs to be done and will include the cost in our quote ready for you to approve.
