This oak playhouse, by James O’Keefe, was built with roundwood timbers and waney edged planks and has wild flowers in its green roof
Being Scottish James referred to it as the ‘wee dinky (small tiny) playhouse’. The frame of the house is built with roundwood oak found within 15 miles (24 km) of the site.
The shape of the house was determined by the curve of the roundwood timbers, as such the design for the home was a compromise between the plan and what was available in the local woodlands. That’s something SunRay Kelley calls evolutionary architecture.
The floor, resting on a rubble trench, was sunken to give more headroom for adults. All of the carpentry was done in a barn off-site and then assembled on-site. The green roof was supported on base-boards that were heat treated to make them flexible enough to take the curve of the rafters. A waterproof membrane was laid over the base-boards and a grid of timbers built to carry the base for the green roof. The green roof base is 100% recycled crushed brick and green compost with drainage. The materials and wildflowers for the roof were supplied by Lindum Green Roofs. Inside the house the walls are insulated with wool and then covered with reed ready for plastering with clay. At the back of the tiny house is a half-circle window with other triangular windows.
