Most of our large garden log cabin models feature 70 mm wall thickness, and some of them have 58 mm wall thickness. All these cabins have full premium cabin features included in the standard price: houses have double-glazed (tempered safety glass) doors and windows, German made tilt and turn window systems, extra thick 28 mm floor boards, 18 mm roof boards, metal storm braces inserted throughout the entire wall in all four corners, 94mm thick impregnated foundation beams, screws, nails and all other wooden components made of carefully selected Nordic spruce. We recommend our optional roof and floor insulation kits, which are easy to install and significantly increase thermal performance. These large garden buildings are widely used as garden table tennis rooms, garden snooker rooms, guest houses, offices and even as show rooms, shops, clubhouses as well as extra classrooms at schools and nurseries.
