Tiny Houses

Tiny houses are the smallest type of small house design, typically ranging from 100 to 400 square feet. They often feature a minimalist design, with a focus on simplicity and functionality. Tiny houses can be built on wheels, making them easy to move and relocate. They're ideal for those who want to live simply, travel frequently, or downsize from a larger home.

Micro homes, on the other hand, are slightly larger than tiny houses, typically ranging from 400 to 800 square feet. They often feature a more spacious interior, with room for a kitchen, living area, and bedroom. Micro homes can be built on a foundation or on wheels, making them a versatile option for those who want a smaller home without sacrificing too much space.

Compact Cottages

Compact cottages are a type of small house design that's popular for its cozy and charming aesthetic. They often feature a more traditional design, with a focus on warmth and comfort. Compact cottages can range in size from 800 to 1,200 square feet and are ideal for those who want a smaller home with a more traditional feel.
