Miami tiny house trades lofts for a spacious single-floor layout

Phoenix Building Solutions has built a tiny house that makes its pitch in the floor plan itself: the Miami is a park-model design with one level, no loft, and a footprint that stretches 34.3 feet long and 11.8 feet wide. At roughly 400 square feet, it pushes right up against the park-model ceiling while trying to deliver the calmer circulation and standing-room comfort that many tiny homes leave out.

That wider stance changes the whole feel of the house. Large glazing and double glass doors pull in light, while the board-and-batten engineered wood siding and metal roof give the model a clean, finished look rather than a stripped-down trailer profile. Inside, the living room is arranged around a sofa, an electric fireplace, and space for a television, which makes the main room read more like a compact condo than a tight RV interior.

The kitchen follows the same logic. Instead of treating storage as an afterthought, Phoenix Building Solutions filled the space with cabinetry and added a dining island for two, giving the home a setup that works for daily meals instead of occasional use. That practicality carries into the bathroom, where the model includes a walk-in shower with a built-in seat, twin sinks, a washer/dryer, and a storage area. Even in larger homes, twin sinks are still uncommon, and here they underline the builder’s comfort-first approach.

The bedroom stays on the ground floor as well, a major departure from the loft-heavy tiny-house layout that still dominates much of the market. There is enough headroom to stand upright, along with a double bed, two built-in wardrobes, and a small chair. For older owners, couples, and buyers who want a more accessible setup, that single-floor arrangement removes one of the biggest compromises in tiny living: climbing into bed.

The Miami also sits squarely inside the regulatory frame that shapes this category. The RV Industry Association defines a park model RV as a single living unit on a chassis for temporary living quarters, with a gross trailer area that does not exceed 400 square feet in setup mode. The Tiny Home Industry Association says most movable tiny house builders work to NFPA 1192 or ANSI A119.5 standards to secure certification and titling, and Phoenix Building Solutions says it is an ANSI A119.5 certified manufacturer based in Greenville, Alabama.

That matters because the Miami is not just another small house with a trendy name. Phoenix Building Solutions says its park models are built for vacation homes, RV parks, tiny-home communities, lakefront properties, and full-time living, and the company says it brings more than 120 years of combined experience to the work. With larger tiny homes increasingly leaning toward apartment-style comfort, the Miami shows how a wider single floor can expand the market without abandoning the tiny-house scale.
