Tasman Cabin Kitset (20m2)

The Tasman Cabin is like the big sister to the Star and Cabana cabins, it’s 2 meters longer than the Star, and 1 meter wider than both those cabins, as well as having the thicker 44mm wall boards for better strength and natural insulation properties. There’s plenty of blank wall space for internal storage options, but the Tasman cabin also looks really great when paired together with added PJ07 Fixed Vented Windows installed vertically either side of the front door, (windows sold separately).

Please note, decking is not included in any of our SheShed kitsets, so if you like the look shown in photos of the Tasman cabin, please talk to your builder about options they can provide.
