The "Bunny House" took me 12 months to build from scratch. 15m3 of concrete foundation, 130 Austrailian Jarrah Railway sleepers, and 8 crossing timbers, acting as vertical columns cast into the slab. 13 Roof trusses, 20 sheets of 18mm ply, 840 marley Modern Roof tiles. 200 bricks used for internal Bunny Pens, with 4x2 and 2x2 fence panelling, separting each pen.
