It isn’t a requirement that this shed be built against a wall—but the structure is designed to take advantage of the wall for strength. So if you modify it to be a freestanding shed, you’ll need to build a conventional stud wall across the back and face it with the same type of plywood siding used on the rest of the shed. For information on how to mark, cut, and fasten wall studs, see How to Frame an Interior Wall (ignore the part about working with drywall because you’ll be using exterior-rated T1-11 siding instead).
Victoria, Australia-based Archiblox designs and makes sustainable, prefabricated modular residential and commercial projects. This simple, straightforward, and modern structure can be used as a studio, office, guest house, or pretty much whatever you desire. Modules can be grouped together for larger spaces and are designed to subtly echo the geometrical arrangement seen in nature.
We built the Colonial-style garden shed shown here from a set of mail-order building plans. The 10 x 16-ft. outbuilding has easy-to-install plywood siding, three large windows and two pairs of doors. The entire building could be used for storage, but we decided to divide the interior space into two separate areas: a 4 x 10-ft. tool-storage area and a 10 x 12-ft. children's playroom.
Build the framework for all four walls. To account for the fact that the front and back walls are different from each other (due to the doorframe in the front) and the side walls must both be sloped (to prevent rain from collecting on the roof), each of these will have to be tackled somewhat differently. It’s easiest to construct the back first, the front second, and the two sides last, as shown in the numbered image below. See How to Frame a Wall for more information before you read the instructions below.
