Our measurements (i.e. 12ft. x 20ft.) are taken from the outside of the wall framing; therefore, they don't include the siding, and/or sheathing.

For true interior measurements, subtract the thickness of the wall framing; 3 ½” for 2x4 walls, and 5 ½” for 2 x 6 walls. Note: 2 x 4 is actually 1 ½” x 3 ½” and 2 x 6 is actually 1 ½” x 5 ½” due to the properties of "finished” lumber.

Our garage walls are assembled with 2x6 spruce wall studs for added strength and durability. For true exterior dimensions, add the siding, sheathing (if applicable), and corner trim pieces. The Canexel siding is 3/8" thick, the cedar siding is 3/4" thick and the log siding is 1 1/2" thick. The wall sheathing varies from 7/16” to 3/4”. The corner trim is 3/4".

If you have any other questions pertaining to the size of the building, please do not hesitate to ask us, we're here to help.

Roof Framing Plan

Common with Archer garages are hip roofs, which typically features a low/moderate slope, with all sides sloping from the center toward the walls of the structure.

Hips are more complicated to frame, sheath, and finish, but are typically simpler to trim and eliminate the vertical wall component of a gable roof style, known as “gable ends”.

Additional consideration should be given to ventilation. Due to its geometry and the lack of gable ends, roof vents must be placed on the roof itself. Consult with your contractor or roofing company, for the most effective ventilation system for your roof.

Overhang Detail

Soffits are the cedar trim pieces that are attached to the underside of the rafter ends.

Fascia is typically the cedar 1x4 that’s used to cover the rafter tips and provide a nice straight level line for the bottom of your roof.

It is important to house your Archer garage walls on a solid concrete foundation. Shown below are two types of concrete foundation that can be poured for your garage. One has a raised which is recommended for uneven surfaces.

Enhanced Siding Package

Included with all of our prefabricated garage styles is our "enhanced siding package" – ESP. This provides great protection from the elements and ensures that your building will be code compliant. It consists of a layer of OSB sheathing and Typar or Home Slicker house wrap, providing a moisture barrier to the elements.

Extra Overhang

The Archer garage roof features a 12” overhang where the roof meets the walls. The overhang is trimmed out with a soffit and fascia board. Extra overhang is offered in increments of 6” [i.e. +6 (18”), +12 (24”)].

Extra overhang choices for a custom garage


Once your custom Archer garage building is completed, there are a few things you can do on the inside to add to the comfort and enjoyment of your new Summerwood design.

Please see Interior Finishing under Advice for more information


If you plan to heat your garage, insulation may be added either at purchase or after-the-fact if you decide to do it later. The walls and roof are constructed in such a way that adding insulation either as an option or on your own is quite simple to do.

Insulation material for a prefab garage


The inside of our garage styles are left exposed to easily accommodate wiring for lighting, outlets, garage door openers, car chargers, power tools, whatever you have in mind. Once the installation is complete, simply have an electrician come and do his thing.

Electrical configuration


Provided you have a water source nearby, your garage pipes can be run for sinks and taps. If you have something a little more elaborate in mind like a shower or toilet, best to make sure it is coordinated with the concrete pad and installation of the garage.
