Ashbrooke, Sunderland
Fed up with gym membership fees, the owners of this semi built a home gym at the bottom of the garden instead. It gets used every day.
The insulated building is clad in low maintenance grey composite boards, with white French doors and a window for fresh air. Inside, thick black rubber flooring protects the base, and a wall of mirrors makes the space feel twice the size.
A wall mounted TV, a heater and plenty of sockets mean the treadmill, rack and bike all have a home.
