If you’re completely serious about your workshop or hobby space, size and structure matters!! You’ll need additional floor space plus sufficient head height so you don’t have to bend down once inside. The UBild 360 Portal Plus Workshop is for serious customers who want a “real” steel building. These sheds use a solid 80mm x 40mm portal steel framing system that are usually found in in a garage or larger steel building. There are 3 x sizes available with the The UBild 360 Portal Plus Workshop … they really are the ultimate man cave! Sturdy, stylish, affordable.
