These are MorHaus buildings, designed to be anything from a backyard office to an emergency shelter after a natural disaster to a guest house.
The homes come in 4 different sizes, ranging from 8×12 to 16×12. Each one comes with a 4×12 porch and various available upgrades. The packages come with pre-cut timber that can easily be assembled by two people — a great DIY option! See a few examples below.
