St. Charles 700 sq ft ADU

St. Charles Two Bedroom ADU

Our St. Charles two bedroom ADU is one of our largest 700+ sf layouts. With lofty 12′ ceilings it feels airy and spacious. It includes everything one would expect from a modern home and we think this one is big enough for a young family with a child. This ADU can be built with either one bathroom or an additional second half-bath or second full bath. The St. Charles cottage is ready for full time living! Our two bedroom ADU can be customized with floor plan variations that include desirable features like accessible layouts, expanded kitchen and living room areas. With an expansive loft there is even plenty of room for long-term storage. Like all of our Alameda Tiny Home backyard cottage ADUs, we can customize to suit individual needs. Whether it be a generous outdoor patio, or wheel chair accessibility, this two bedroom ADU can have the comforts you want in a long-term home.
