Maximize your property's utility storage footprint, secure your vehicles, and build your ultimate backyard workshop with the extra-deep Duramax 12'x26' Imperial Metal Garage Dark Gray w/ White Trim (SKU: 55151). Explicitly engineered to function as an extended standalone vehicle garage, industrial equipment depot, or massive storage facility, this premium metal building delivers exceptional walk-in vertical clearance. The extended 26-foot depth provides ample space to comfortably park a vehicle while leaving a massive area at the back for deep workbenches, tool chests, and heavy machinery. The Imperial series stands as the definitive, zero-maintenance alternative to costly brick-and-mortar additions or high-maintenance wooden structures.
Unlike cheap, low-grade metal buildings that easily dent, rust out, and warp under high winds, the Duramax 55151 garage is built with thick, hot-dipped galvanized steel framing elements and wall cladding panels. These high-grade metallic profiles are anchored together by heavy-duty internal steel columns and extended roof trusses to provide maximum resistance against harsh seasonal elements. The striking dark gray wall panels contrast beautifully with the crisp white trim, making this large garage structure a premium architectural asset to any residential yard, workshop pad, or farm landscape.

Interested in the 12x26 only issue is I need the rear access door on left not right side. Is this an option??
The walk door can go on either side at any location front or back due to the modular nature of the building. I would also suggest if you are interested to go ahead and order ASAP. We are looking at substantial price increases on all our products due to the tariffs.
