I purchased a 30' X 50' building 6 years ago and love it. It is officially my "man cave", I use to restore cars and as a music studio for the band to practice in.

I needed a steel building to be able to build close to the property line. It has been on my bucket list for a long time to build a garage where I can work on my project cars and from start to moving in I'm 100% thrilled with my Allied Steel Building.
