Minneapolis St Paul Two Car Garage Construction Specifications

Two Car Garage Construction Specifications

Knowing whats under the hood or should I say shingles, is the most important and often most overlooked part of the garage construction process. Knowing the specifications that make a garage a Western garage is as important as choosing the correct siding, roofing and windows.

While there are hundreds of garage styles, shapes and sizes to choose from, every garage at  Western Garage Builders starts with the same specifications. 

Garage contractors all over the counrty will talk about everything but how they build their garages. We're so proud of our garage construction process that we put it out there for everyone to see. The funny thing is, except for code changes and material improvements today's Western garage is built pretty close to the way my father first built them back in 1949. 

If it ain't broke don't fix it my father used to say so after 67 years and thousands of garages around the Twin Cities still standing I guess he was right!
