Description
Looking to create a contemporary home extension that offers something unique? Perhaps you require additional living space, a home office or a garden gym. The Harlow Insulated Garden Room provides an all-purpose space, designed specifically for year round use.
This 6m x 4m garden room boasts an architecturally stunning exterior, with clean angles and a geometric shape. Our unique wing design creates an ultra-modern and stylish aesthetic, guaranteed to become a feature within your garden. The wings create a sheltered porch to the front of the building, perfect for rainy days or for added shelter in the summer. Manufactured to order here in the UK by our highly skilled team, using only the highest quality materials, you can be confident in the quality.
So much more than a summerhouse, this building is packed with premium features as standard. The walls, roof and floor contains Eco-quilt multi-foil insulation, which provides the same insulation as 100mm of glass wool. This combined with the double glazed windows and French doors ensures a warm, welcoming and comfortable interior all year round. The 100mm double skinned walls have also been designed with an easily removable internal panel to enable you to fit and conceal any electrics you may require – perfect for tidying away all your office cables. Finally the roof is covered with a superior waterproof rubber membrane, designed to last for 50 years!
Available in multiple variants, this garden room is versatile and customisable. Looking for more windows? Not a problem. Wanting to move the door location? We can do that. Just give us a call and we can discuss the options with you! Mercia Insulated Garden Rooms are manufactured here in the UK, using sustainably sourced and regulated timber.
