Going Fast The Creswell Insulated Garden Room 3m X 4m With White Upvc Instant 90% Discount [IHh6fAMW]

The 3m x 4m Creswell is a clean and contemporary insulated garden room, perfect for those looking to add a modern extension to their garden! This all-purpose garden room has been designed and built for year round use, ideal if you’re looking for a home office, guest accommodation or simply somewhere to unwind.

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!

The Creswell exterior has a classic modern design with stunning architectural features. The recessed front aspect creates a beautiful frame to the building as well as providing a welcoming sheltered entrance and veranda, ideal for rainy days! The open-plan interior creates a bright and airy space, perfect for working, entertaining or sitting back and relaxing. Manufactured to order here in the UK by our highly skilled team, using only the highest grade materials, you can be confident in the quality.

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.
