This is my first attempt at a geodesic dome type shed. 3m Radius 3V with 1M riser panels. It is constructed from treated 4x3 timber frame paneled in 11mm OSB with skimmed plasterboard internally. It is insulated with fibreglass sandwiched between. It acts as my office and also doubles up as a cinema It has a mezzanine level for storage etc with a swinging bannister/ladder contraption, check out the photo. The dimensions are; Height, about 4M to the top of the skylight. Width is roughly 6M diameter, with 7M front to back including the porch.
I worked out the dimensions with an online tool and created the rest of the design myself. It took roughly 6 months to build the main structure, working at the weekends. I expect the materials cost up to £3K in total
