Description

Built for year-round use, the Hawthorn is designed to feel robust, comfortable, and considered from the outset. With high-performance insulation, a fully timber-framed structure, quality glazing, heating, electrics, and a carefully resolved finish, it offers a dependable and refined extra space without the need for a fully bespoke design process. Its broader footprint and balanced front elevation give it a calm, substantial presence, making it especially well-suited to customers seeking a room that feels both versatile and well-established within the garden.

Build & Specification

The Hawthorn is built on a ground screw foundation system with an insulated timber base, breathable wall construction, and a flat roof with single-ply weatherproof covering. The building includes insulated floor, wall, and roof elements designed to create a comfortable internal environment throughout the seasons. The specification also includes a vapour barrier and internal wall finish, with a target U-value of 0.23 W/m²·K, helping to support both comfort and efficiency.

Inside, the room is designed to feel complete and practical from day one. The standard finish includes LVT flooring, skirting boards, and an electrical setup that includes sockets, LED downlights, external lights, CAT6 data cable, an outside socket, and an electric panel radiator. Decoration is not included, but can be discussed if required.

Reassurance & Warranty

The Hawthorn is supported by a 20-year warranty on the roof covering, a 10-year warranty on the foundation and structure, and a 5-year warranty on windows and doors, offering added reassurance in the quality and longevity of the build.
