PLUS 1 Home Kits introduces the Mini Coach house, designed for your comfortable and affordable living. You’re buying a DIY system (a Pre-assembled Framing Kit) that is perfectly designed for easy assembly on your concrete slab. It’s important to note that the steel frame structure does not include pricing for finishings including doors, windows, electrical, plumbing, and other finishes. However, it has allowances in the steel frame structure design for all elements required. Your electrician and plumber will be adding in their materials with ease. Our Mini Coach House has the potential to add value to your home as an ADU. This quaint little home measures 17ft W. x 10ft D., offering 170 sq. ft. of total open inside area. Our Mini Coach house makes a great little ADU that can be placed on your existing property (if your local building authorities approve of your lot size). A fun getaway for a guest house or back lot rental.

This model is designed to be constructed on a concrete slab with no deck option. The deck and flooring system can be added as an upgrade option.

*As has been noted, there are no finishes included with the steel frame kit.

Cost and Time Efficient: Have we mentioned our FREE shipping yet? Our steel home kits are delivered free to any location in the mainland of USA (in most cases). With pre-assembled steel panels, walls, ceiling & roof, and a detailed step-by-step instructions booklet. These kits are easy to construct, saving time and labor costs, which means more money is staying in your pocket.

The Benefits You’re Getting with Your Steel Framing:

Your PLUS 1 Home Steel Kit provides maximum strength and durability, ensuring your investment lasts for generations. All our steel frames are manufactured using pure G90 galvanized USA steel.

  • Did you know steel frames are environmentally friendly and sustainable?
  • Additionally, our fabrication and manufacturing process promotes efficiency in the installation!
  • Your steel frame is 100% termite and borer proof.
  • It also won’t shrink, twist or warp with climate seasonal changes.
  • Steel won’t ignite or combust in a house fire. In fact, some insurance companies offer a discount when you have a steel framed home.
  • As noted earlier, service holes in framing make it easier for trades to run cables and pipes.
  • Did we mention steel is also fire resistant?
  • You’ll be an ally to our environment because steel is also recyclable.
  • Besides the above benefits, steel also provides durability and flexibility in structural design.
  • And finally, steel is corrosion-resistant, and does not rot, buckle, or splinter
