Shipping Container Home Starter Kit

A modified Simple Box container could make a great space to live in – especially in rural areas.

The Tiny House movement and Shipping Container architecture are here to stay. 

Although we aren’t home builders, we can help you get a strong start:

  1. Choose your container.
  2. We’ll do the basic modifications of adding windows, doors, spray-foam insulation and framing for 40, 20 and 10 foot shipping containers.
  3. We can deliver your Box to a finish-carpenter to complete the container house or vacation cottage of your dreams!

The box is beautiful. To our surprise, instead of painting over the all the labels and numbers, the Mod team actually removed them all before painting! So, all the walls and doors look perfectly smooth. The paint job looks great!
