Coral Gables commission affirms Board of Architects denial of glass garage door for 6901 Triompheel St.

Coral Gables City Commissioners on July 1 upheld a Board of Architects decision denying a proposal to replace the single‑story garage opening at 6901 Triompheel Street with a full‑glass, hurricane‑rated sectional garage door.

The commission’s action affirmed an earlier special‑master ruling and allowed the homeowner to reapply with a modified design without paying a new application fee.

The homeowner, Sergei Katonnikov, told the commission he sought an energy‑efficient solution to daylight a deep, dark garage and argued nearby homes already display modern interventions such as visible solar panels. "Sustainability doesn't just come at a citywide scale — it also comes at the level of individual residents," he said during the hearing. Katonnikov said he would accept a design compromise but prefers more glazing than staff and the Board of Architects have approved.

City Architect Juan Riesco and Assistant City Attorney Gus Biles described the review history: staff initially recommended limited glazing (a narrow top panel), two panels of the Board of Architects approved a top‑panel compromise and the applicant chose to seek a rejection so he could appeal; a special‑master hearing later denied the appeal. Riesco told commissioners the house is a 1950s ranch and the proposed full‑glass door reads as a modern, industrial element that the Board judged incompatible with the building and its neighborhood context. He said the Board has accepted more contemporary doors in other parts of the city but treats each application case‑by‑case.

Commissioners pressed both sides on options to resolve the dispute without further delay. Commissioners asked whether a redesigned door with larger‑framed or frosted glazing might be acceptable; Riesco said staff repeatedly offered a top glazed panel as a proportionate compromise and that a full‑glazed door is inconsistent with the house’s architectural character. The commission discussed whether to remand the case to the special master or affirm and direct staff to accept a revised application; commissioners ultimately voted to affirm the special‑master decision while directing staff to waive the application fee if the owner submits a new, materially different design to the Board of Architects.

The formal motion carried unanimously. The commission also asked staff to return to them with shop drawings for any proposed replacement windows or doors so commissioners and staff can review finer construction details before installation.

Why this matters: The case illustrates how Coral Gables’ design review process balances individual property owners’ desires for modernization against the city’s long‑standing architectural standards for historic neighborhoods. The commission’s decision preserves the Board of Architects’ role as the primary design arbiter while offering the homeowner a low‑cost path to propose a revised solution.

What's next: The city will waive the new application fee if the homeowner files a materially different design; staff will work with the applicant and the Board of Architects on shop drawings, and commissioners requested a return update if a revised design is submitted.
