A Chelsea roof is transformed from a bleak open space to an enclosed, child-friendly, garden terrace. The space has been softened by the use of pine decking, mirrored walls, a water sculpture, artificial grass and an imaginative use of lighting.

The most important concern on a roof terrace is the overall weight. Decking is a light material ideally suited for such situations. Planting is best confined to pots where the depth of soil can be controlled : soil is extremely heavy when wet. Grasses and a simple, bold colour scheme are very effective.
