People are often confused as to why a 100 square foot costs more than $150 per square foot. The mindset in America is to look at the cost per square foot. Increasing the size of a room by 50 square feet costs almost nothing. Basically, all you're paying for is the roof and flooring, and maybe a little extra wiring and plumbing. One of the easiest ways to make a house cost less per square foot is to make it bigger.
Our portable homes are made from quality materials; and the materials alone typically cost $200 per square foot of house. The house is finished with hardwood floors, pine walls, built in cabinetry, stainless steel counter and more. Our green homes are fully insulated with double pane windows and an adequate heater. Many other "competitor" homes don't include the proper insulation and heating, and are therefore subject to condensation.
Our homes focus on the details that make it more than four walls and a roof. We make each door by hand because you just can't buy the right door for a house like this. Windows are special order items that give the house a timeless look. The porch posts are detailed, and the siding reflects the overall quality of the house.
Typically, it takes between 550-850 hours to build each tiny house. You can certainly save money by building it yourself. A few people on the internet brag that they can build a tiny house for $5000. Those claims aren't true. The trailer, windows and heater cost roughly $7,500 combined. The least expensive Tumbleweed House built was by Dee Williams; she built hers for $10,000. About ½ the materials were recycled.
