Smithaven 4-Season Plans

The 4-Season Smithaven is an incredibly unique hobby shed that comes in sizes 10×16 to 12×24. This diy wood building kit is defined by its abundant natural light with multiple small insulated windows, including transom windows and additional headroom provided by the long shed dormer. These detailed office shed plans can be purchased and reviewed digitally, plus we’ll ship you a printed copy for use on the build site. You can purchase the Jamaica house design plans and opt to supply your own 4×4 rough cut lumber and materials, or you can buy our matching small cottage kit. All of the rough cut lumber in our kits is locally and sustainably sourced eastern white pine. The cottage kit for the 4-Season Smithaven comes with the necessary insulation and sheathing to be livable year round, no matter where you happen to build it!

The possibilities for this garden hobby shed are endless! The unique asymmetrical roofline lends itself to being the perfect treehouse, artist studio, or office. The long shed dormer gives the Smithaven higher ceilings and more natural light than many other of our Jamaica cabins of the same sizes. Plus, all that natural lighting makes this the perfect retreat for reading, writing, and studying! Set up some adjustable curtains or shades and you could use this building as the perfect backyard guest house or she shed.

Overall, the more open design of the 4-Season Smithaven makes it perfect for those that want the feel of an outdoor cottage or small cabin without the usual cramped interior. Afterall, the small cottage lifestyle is all about peace and tranquility amongst nature: so the more windows and natural light to enjoy it with, the better! Plus, the sheathing and vapor barrier will guarantee that you will be able to enjoy the great outdoors whether rain, sleet, or snow.
