Mortise and Tenon Annex Features

Roof Style: Shed Roof

Big buildings need big additions! Our Vermont Cabins and Two Bay Garage use Mortise and Tenon joinery in their construction, and this series of annexes is built to match. The framing of these annexes is 8×8 rough sawn hemlock, giving these additions strength and longevity. As you choose which annex is right for you, think about how you anticipate using the extra space.

Overhang

This overhang grants you the extra space that you need while not technically adding to the interior square footage of your building, and is the simplest annex we offer. If you are looking for outdoor, covered storage or a place to relax in the shade, an overhang kit is ideal.

Porch

Much like an overhang, a porch is open air with the added benefits of having a floor system. This DIY wooden porch kit includes everything you need to add a covered porch with floor decking to your Vermont Cabin or Two Bay Garage. 8×8 rough sawn hemlock mortise and tenon wall framing with angle braces, hemlock rafters, corrugated metal roof, and aluminum flashing are used. Many Jamaica Cottage Shop buildings come with a porch, but not all do. Adding a porch is a wonderful way to incorporate useable outdoor lounging space with your cottage, garage, or cabin. All buildings can be enhanced by adding a solid post and beam porch. Set up some chairs or a hammock along the porch to enjoy the warm sunny days right from the comfort of your backyard. A large porch adds a welcome aesthetic style to many building models.

Enclosure

With walls on all sides, the Mortise and Tenon Enclosure is the perfect solution if you want to make our timber frame Vermont Cabins and the Two Bay Garage includes everything you need to add an extra room to your post and beam building. Purchase this kit to create additional rooms, a workshop, or an enclosed storage area. For those who are working from home, the kit could be installed on the garage to be used as an office that is separate from a living area.

FREQUENTLY ASKED QUESTIONS

What is a Pre-Cut Kit? What is included in this package?

The Pre-Cut lumber package has all the framing members cut and ready for assembly. It includes siding, roofing, pre-dimensioned trim, and fastening hardware. Many designs also include windows and doors. The floor system, walls and rafters have all been cut, color-coded and part numbered. The detailed cut list coincides with the color-coded exploded view. The head scratching has been removed, the headaches of finding the correct angles and the aggravation of starting from scratch has all been simplified. The kit is geared to a do-it-yourself homeowner with beginner-to-beginner knowledge of carpentry.

Should I buy a Pre-Cut Kit or Fully Assembled Building?

We design our kits to be organized and easy to understand. If you have basic carpentry skills and are looking to save money, a kit is a great idea for you. We ship our kits  all across the continental USA and part of Canada.

What is a Complete Shell and What Comes With It?

A complete shell is an uninsulated building. As a kit, it includes everything required to assemble the building including hardware, precut framing, siding and roofing as well as doors and windows. Hardware, millwork sheathing and DIY plans have been enclosed. Each piece is color coded and part numbered. The exact itemization of what is inserted can be found on the specifications tab of the website for each product page design.

What is the difference between a 3-Season and 4-Season Insulation package?
