Zip Kit Homes spent over a decade building a lot of different homes—over 500 homes and multi-family projects. After experimenting with all different types of building construction: standard site-built homes, panelized homes, modular homes, etc., they recently launched kit homes to offer precision-built, sustainable small homes shipped anywhere in North America. They also offer many site-built floor plans that are both energy efficient and efficient to build.  Photo 3 of 11 in 10 Kit Home Companies to Watch
