ADUs & Utility Structures — Nature Coast to Tampa Bay

Whether it’s a backyard ADU (Accessory Dwelling Unit) for rental income or family, or a utility structure for storage and workspace, we design and build these as fully licensed, permitted structures — not sheds dressed up as living space.

What we build

  • Accessory dwelling units (ADUs) — in-law suites, rental units, guest houses
  • Utility structures and outbuildings — sheds, well houses, pool equipment and storage buildings, and workshops
  • Fully permitted design and construction, including stamped plans through our Mobius Architecture partnership when required
Before you plan
Not sure if your property qualifies?
Most homeowners assume they can simply add an ADU — but zoning, lot size, and setback rules vary by county, and not every property qualifies as-is. We check ADU eligibility for your specific property as part of your free design consultation, so you know where you stand before you plan around it.

Freddie and his crew quickly had a clear, precise estimate done in a timely manner and had me scheduled in as soon as both of calendars lined up.
