The shed is a scale model of the Great Pyramid at Giza, Egypt. (It reminds us of a visit there). It was a well-known fact in my younger days that a miniature pyramid had magical powers and would sharper any razor blade placed beneath. This pyramid was built to house my mower and hence to keep the blades sharp! It is built in the correct alignment to the stars, for maximum sharpening power. The local "Slow Worms" seem to find it cosy too.
The construction is a timber frame, clad with marine plywood and painted with a wax-based fence/shed paint. The hardest part was working out the optimum size to house the mower, using standard sheet sizes, and the shape of each piece.
