640 sq. ft. Modern House with Two Bedrooms & Bunks!

These house plans look perfect for a retirement cottage, a small family home, or a vacation property. At just 640 square feet, this is just above tiny yet still well within “small house” limits. The clever layout could easily sleep six people between the two twin bunk lofts and the two first-floor bedrooms.

One of the bedrooms is shown as an office but has the exact dimensions of the primary bedroom. There’s a single full bathroom and a second utility room the same size. Turn that into a powder room with a washer/dryer unit. The center of the home has an open-concept living/dining/kitchen space that looks out over a lovely porch. What do you think of this design?

Great for a weekend getaway retreat or the ultimate in downsizing. This simple modern cabin is designed for economy and simplicity of construction. With the two Bunk Lofts, sleeping for six can be provided in this small space if the Flex Room is built out as a second bedroom. If the intention is a more intimate getaway and the extra bedroom is not needed, the Flex Room can become a sitting area, dining area or study.
