An architect is not required for every good building design project. Although, I was one when I designed my garage, I made it an easy and affordable project by working with local garage and storage builders A-Shed.
I selected a few extras beyond choosing one of there standard garage model packages:
Added a sub-floor for a storage loft.
Steeper pitched roof, as high as local zoning allows, to allow ample head room in storage loft space.
Added extra windows where I wanted them.
Translucent roof vents for added natural light.
Here is a link to photos of some of A-Shed's "customized" garage projects, including mine.
I was stunned by how quickly A-Shed constructed the garage. To demonstrate, here are several photos of Day 3 of construction:
Separately, I coordinated the installation of a cantilever automated gate (of black chain link fencing with redwood colored privacy slats) to close off the entrance to the driveway and garage from the public alley. This required three trades: The fencing manufacturer who fabricated the gate, the installer of the remote motorized gate mechanism, and the electrician.
