Living on the edge of Exmoor, Rob takes his inspiration from the rolling countryside surrounding his home, where each Bough House sculpture takes several months to construct. The designs do not follow an explicit plan or process, each piece is unique. They evolve and flow freely, as part of a creative journey which has no natural limit, whilst also revealing great logic and engineering integrity. Every aerial walkway or staircase leads to a room - there are no dead-ends and every turret and tower can be reached.

A man walks in the early morning to start his day picking tea leaves at a plantation in Nandi Hills, in Kenya's highlands region west of capital Nairobi, November 5, 2014. Emerald-coloured tea bushes blanketing the rolling hills of Nandi County have long provided a livelihood for small-scale farmers, helping make Kenya one of the world's biggest tea exporters. But ideal weather and bigger harvests, instead of producing bumper earnings, have led to a glut of Kenya's speciality black tea. (Photo by Noor Khamis/Reuters)
