Annex Modern Garage Dimensions
| A | B | C | D |
|---|---|---|---|
| BUILDING DEPTH | BUILDING HEIGHT | WALL HEIGHT | ROOF HEIGHT |
| 12' | 12' - 6 7/8" | 8' - 4 1/2" | 4' - 2 3/8" |
| 16' | 13' - 8 3/4" | 8' - 4 1/2" | 5' - 4 1/4" |
| 20' | 14' - 10 5/8" | 8' - 4 1/2" | 6' - 6 1/8" |

| 28' | 17' - 2 3/4" | 8' - 4 1/2" | 8' - 10 1/4" |
Our measurements (i.e. 12ft. x 20ft.) are taken from the outside of the floor & 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 2x6 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.
Wall Plan
Wall plan configuration with an enlarge detail for an Annex garage wall component
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 your building, please do not hesitate to ask us, we're here to help.
Roof Framing Plan
In strong competition with hip roofing and gable roofing, are flat roofs. These roofs are common with Annex garage styles, being one of the easiest roofs to install and frame when compared to other roof styles.
Due to its geometry and low pitch, flat roofs do not always require vents. If vents are desired, they can be installed on the tallest wall or sidewalls of the building.
Consult with your contractor or roofing company, for the most effective ventilation system for your roof.

Foundations
It is important to house your Annex garage on a solid concrete foundation. A raised concrete foundation is recommended for uneven surfaces. Visit our Foundations page for more details.

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

Finishing
Once your custom Annex 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 Annex Garage from Summerwood.
Please see Interior Finishing under Advice for more information
Insulation
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.

Electrical
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 example
Plumbing
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.
