Classic Haven Garden Room

A budget-friendly, fixed-spec garden room with an angular front elevation, diagonal roof overhang and glazed side panels, supplied in selected standard sizes.

Classic Haven

The Classic Haven is a fixed-spec installed garden room with a distinctive angular front elevation and diagonal roof overhang. A single opening door with a glazed panel on either side brings plenty of natural light into the room, making it suitable for a home office, studio, gym, hobby room or leisure space.

It is built with 97 mm SIP wall and floor panels containing 75 mm insulation, an 80 mm PIR-insulated composite roof, pre-adhered MDF internal panels and commercial-grade laminate flooring. The Classic range is supplied in selected standard sizes with no bespoke, glazing or flooring upgrades.

For thicker insulation, more cladding choices and custom upgrade options, see our Premier Haven model.
