We have done a lot of research on efficient apartment living at the Monolithic Dome Institute. The designs shared here represent the most current floor plans we recommend for studio apartments. Our sister company, Round Flats, in Italy, Texas, owns and operates studio apartment complexes. These clusters of rental studios have taught us that the following plans are what renters and owners find they like the best. If you are considering tiny house living or want to build a mother-in-law apartment, start with a residential feasibility study.
