Atcost garden buildings are a modern and versatile way to add extra space. The robust composite garden buildings can be used for home offices, home gyms, playrooms or a relaxing retreat. These Garden Rooms look great, are easy to install and require little maintenance. 

The Seymour Collection is available exclusively in South Wales from Atcost, and comes complete with an aluminium French door, a rubber roof for added weather resistance and wall caps for a seamless finish.

The Seymore is a stunning prefabricated building offering superior qualities over standard timber construction buildings.
The ease of construction means you don’t need carpentry skills to erect one of our buildings and also don’t come with the maintenance. 
Made primarily of composite materials, along with an aluminium double door and rubber roof means you can enjoy your garden room for years to come with minimal maintenance.

The Seymore Deluxe takes the standard version to the next level with an extended veranda. Whether it be for a hot tub or extended storage. The deluxe version offers numerous possibilities… Personally, we like the hot tub with the roof offering all year round protection
