DIY Haven Garden Room

The Premier Haven garden room is exactly that – a little self-build haven for your garden.

This angular design offers a striking visual in your garden, with a diagonal overhang giving a real sense of design. A single opening door with glazed panels to either side makes the front elevation sleek and clean, allowing plenty of light into the room.
