There are a number of solid custom prefab and modular home companies that will design and sometimes build your prefab project to spec. Unlike companies that only specialize in a set of standard plans, these homes are designed by the firms architects to your preferences, which is particularly useful if you have a unique lot (such as one with a significant  slope), a town with a particularly design standard and design review board, or you just want a home built to your exact specifications.
