The contemporary modular design of the Adley 3m x 4m Alveston Insulated Garden Room offers extra living area, ideal for a work space within your home or as a place to host visitors. The Alveston collection is produced in various dimensions, crafted in the UK by our team of highly skilled artisans, using premium materials, ensuring top-notch quality. This structure is equipped with Eco-quilt insulation in the walls, roof, and floor to keep the interior warm, cozy, and pleasant year-round. Kindly Note: The cost of this product covers the complete installation of the structure in your outdoor space. Always consult your local planning authority before making a purchase. A stable and even base is necessary for this, which can be made of either solid concrete or concrete slabs. It is advisable to further protect the floor of this garden room by covering it with carpet or laminate to minimize damage to the flooring. Kindly Note: These Insulated Outdoor Spaces are NOT pre-treated or painted. The use of wood preservatives is not part of the installation service. To qualify for our 10-year anti-rot warranty, the structure must be treated annually with a high-quality spirit-based wood preservative.
