Call it a mother-in-law suite, a granny flat, a guest house, a backyard office, an accessory dwelling unit, or just your own sweet compact home. Whichever name you choose for it, there’s no denying the fact that the compact prefab kit is set to explode in popularity. Growing particularly fast in the American South and West, the market for small homes built on the same lot as more conventional residences will likely only continue to grow in the near future as populations boom and cities work to make room for new residents. At the same time, many people are downsizing or looking into aging-in-place close to family members.
Prefab homes are higher quality and more accessible than ever before, and many of them require no building experience to assemble. Whatever your preferred design style or intended purpose, there’s a kit out there for you that can be just about move-in ready in a matter of days. ÖÖD House

Initially designed as a hotel concept by brothers Andreas and Jaak Tiik, the ÖÖD House now comes in studio, office, and playroom versions, as well, all featuring a stunning mirrored or all-glass exterior. It also comes with interior finishing, fixtures, ventilation, heating and cooling, kitchen cabinets, and appliances; all you have to do is connect utilities and prepare the foundation. Amazingly, it takes less than eight hours to build, and costs around $65,000.
