The bed frames were constructed from 34x34mm softwood. They were split into roughly three sections of equal size. So, the seat were about 600mm wide with a 600mm walkway.
The frame was fixed to the floor, wall and existing cupboard. There was clearance above the wheel arch so no load is applied to the boxed covers.
The aim was to separate one area for bedding and allow the other area for storage of outside gear, tools and long-term food storage.
The end of the bed would be covered with door access to the space below.
