Columbus, Ohio
Infill Triplex
A completed triplex on a narrow Columbus, Ohio, lot: three condominium homes over 3,000 square feet each, stacked on mirrored plans with private basements.
The project
The Infill Triplex fits three independently owned homes onto a narrow Columbus lot, replacing a single-family house lost to fire. Each home builds up instead of out, rising from a finished basement through two floors on a mirrored plan with its own front door.
Three homes on a narrow Columbus lot
A narrow lot usually means one house. Here it holds three, because the design builds up instead of out. Each residence is organized vertically: a finished basement, a main floor, and an upper floor, with living, dining, and sleeping space spread across the three.
The exterior massing stays clean and compact, and it makes efficient use of the site. With owner-directed finishes and finished basements, each home exceeds 3,000 square feet, far more room than the footprint suggests from the street.
Three homes share one structure.
Each still has its own front door.
Mirrored plans, separate front doors
The three homes use mirrored layouts. Mirroring simplifies the shared structure and lines up the systems the homes have in common, which keeps construction straightforward.
It does not make the homes interchangeable. Each has its own entrance and its own sequence of rooms, and the units are split vertically with no shared living walls. The result feels closer to a house than an apartment, with the efficiency of shared infrastructure behind it.
Finished basements add a bedroom and bath
The basement in each home is finished living space with an additional bedroom and bathroom. That level turns a compact footprint into a substantial residence, and it gives each home a private suite set apart from the main living floors.
Above the basement, open-concept kitchen and dining areas carry the owner-selected finishes. The exterior keeps a clean urban edge, and the interiors open up with volume and warmth behind it.
Condominium ownership in one building
The development is structured as three condominium units, so each home is owned independently within the shared building. Condominium ownership, mirrored plans, and vertical separation work together: three owners share one structure and one lot, and none of them shares living space.
Variances, zoning, and permitting
Arcfluence served as architect of record. The work included the variance approvals, the zoning documentation, and final permitting, with each design decision checked against what the code and the city would allow. Construction and documentation are complete.
