SAVED!
Whether you're seeking a vacation cottage or a tiny, affordable primary dwelling, this collection of ~400 sq. ft. house plans is sure to please! Most designs below offer one bedroom and one bath. Many floor plans also feature open layouts and outdoor living (e.g. a front porch), which can make a small home feel larger than it actually is.
Need a garage? A few tiny house plans below feature a garage. To see more tiny designs with garages, try exploring the tiny house plans with garages collection, which showcases home designs under 1,000 sq. ft. with garages. Need a big garage? Check out our collection of tiny barndominium plans.
Given how small these plans are, some could potentially be used as ADUs (accessory dwelling units). ADUs can be rented out to help cover the mortgage of the primary house. Or, they can be turned into art galleries, writing workshops, home offices, or bedroom suites for aging in-laws or adult children.
As always, be sure to discuss your plans with your home builder and/or local building authority to make sure they work for your area.
