Case Study: Midi Garden Office in Tunbridge Wells
Midi garden office for a customer in Tunbridge Wells. The building sits at the bottom of a split-levelled garden and provides the perfect work from home solution, just a few steps from the house.
The Midi is designed for up to 2 people and our client opted to face two desks back to back in the centre of the room.
Options included heating, downlights in the overhang, natural oak flooring and a sand coloured composite decking that was later integrated into the steps leading down to the building.
