Haven Garden Room

A striking installed garden room with an angular front elevation, diagonal roof overhang and generous glazing for work or leisure.

Premier Haven

Haven Garden Room

The Haven is a distinctive installed garden room with an angular front elevation and diagonal roof overhang. A single opening door with glazed panels on either side creates a clean, balanced frontage and brings plenty of natural light into the room.

The Premier Haven uses 122 mm SIP wall and floor panels with 100 mm insulation. The roof is an 80 mm PIR-insulated composite panel on most sizes, increasing to 100 mm on rooms with a 4.0 m depth.

A more budget-friendly alternative is the fixed-spec Classic Haven, which uses 97 mm SIP wall and floor panels with 75 mm insulation.
