Arched Cabins out of the Houston area set out to design and manufacture tiny houses that they could sell for only $5k and they absolutely blew it out of the water! They can be made in widths ranging from 14’ to 24’ and any length that you choose and costs are from $200 to $320 per linear foot (based on the width). The base price only includes the ribs, beams, paneling, flooring, and insulation but it’s a good start for a low price!
When it’s all said and done, a 20’ long 320 square foot house will end up costing you as low as $7,500 or up to $14,000 if you have the company do it all for you.
They come in 20 different colors and are extremely well-made. This is what the shell looks as it’s being made:
