24Wx32L Garage Build

I was able to purchase a piece of property that was coming out of bankruptcy about 4 yrs ago...It has a small 950 sq house on it, the existing detached garage is 30 x 30 x12. I am in the process of submitting for a zoning variance to build a 50 x 60 x 12 metal building on it. I thought the 30 x 30 garage was going to be big enough....Also going to put a 40 x 8 shipping container it for storage of parts. The property is zoned for horses and is in a older part of vegas northeast near nellis afb...
