It is becoming increasingly popular for people to extend their living areas outdoors, into the garden. The commercial use of decking and walkways is also growing, with restaurants extending their dining areas and pubs providing smoking areas etc.

One of the best ways to create ‘a room in the garden’ is by building a timber deck. Simple and quick to build, it requires less groundwork than masonry construction, particularly on sloping or rough sites, and can blend in well with existing landscape features. It is also relatively easy to provide for simple changes of level with ramps or steps, and to allow for future extensions.

Case studies

Acharacle is a small and remote community on the south-west tip of Loch Shiel, some 40 miles west of Fort William. For many years the village had campaigned for a new primary school and community space to replace the old Victorian buildings, which were becoming difficult and expensive to maintain.

Hopkins Architects has been involved in the design of new facilities at Norwich Cathedral for 14 years; the first phase of development, the Refectory (the subject of a TRADA Case Study in 2007) forms one side of the Cloisters and the second phase, the
now-completed Hostry, runs at right angles to it.
