The Bedouin Tree-Shed that topped the Nature's Haven category has been an eight-year labour of love for expedition organiser Daniel Holloway, who built it around two living tree trunks in his back garden in Blackheath, south London.
When the nation went into lockdown it soon became a sanctuary for the 55-year-old, his wife Beccy, 51, and their children Sam, 12, and 14-year-old Lyza.
The extraordinary space began life as a conventional garden shed - but has been extended and modified to encompass three levels with a footprint of roughly 5m by 5m.
It contains a host of treasures from Daniel's extensive travels through Africa and is built around the trunks of an Ash and an Evergreen Oak. Alongside the African artefacts, the interior is decorated with vintage etchings and specimens of butterflies alongside finely carved ancient hardwood Indian columns. A wood-burning stove provides comfort during the cold winter months with furniture plundered from skips and reclamation yards. The floor is made of oak planks and follows the contours of the trees inside.
