Three early 1900s masonry buildings in the heart of downtown Dayton have been transformed into a 12-room boutique hotel and mixed-use commercial destination, completing a years-long revitalization effort rooted in historic preservation and community investment.

The Merchant Block, located at 520 3rd St., unites the Stuckey, Harris and Bank of Dayton buildings 鈥� originally constructed between 1911 and 1913 鈥� into a single development featuring ground-floor retail and The Inn at Dayton above. A two-story addition connects the structures behind their historic fa莽ades, housing the lobby and gathering spaces and opening to a central courtyard. The project encompasses 21,045 square feet.

The Inn at Dayton welcomed its first guests over Memorial Day weekend 2025.

鈥淭he best way we can continue to honor Bill Stoller is to realize his vision for Dayton,鈥� said Wayne Marschall, chief executive officer of The Stoller Group, in the Top Projects submission form. 鈥淭his project shows that vision coming to life.鈥�

Stoller, founder of Stoller Group and Stoller Family Estate winery, began acquiring the properties more than a decade ago before his death last year. Twin Towers LLC, the development arm of Stoller Group, led the effort.

General contractor R&H Construction navigated significant structural and logistical challenges throughout the project. All three unreinforced masonry buildings underwent full seismic upgrades using an inside-out approach 鈥� a new internal wood frame system was tied to existing brick with helical ties, avoiding the need for braced frames throughout the interiors. When deteriorating soil was discovered beneath one foundation, helical piles were installed to prevent further settlement.

Acoustics presented additional complexity. A 3-inch concrete topping slab was poured at the second floor to limit sound transfer between the hotel rooms and the lively commercial spaces below. Entry doors received acoustic seals that engage automatically when the door lock is activated.

Safety performance was tracked using HammerTech, a structured site management platform. All 690 workers completed required orientations, 1,372 pre-task plans were submitted and the project finished injury-free.

On the sustainability front, a 66-kilowatt solar photovoltaic system with 136 panels was installed and is projected to offset approximately 930 tons of CO鈧� over its lifetime. The development is expected to use roughly 30 percent less energy than a comparable baseline building and is on track for LEED Gold certification.

The project also preserved the legacy of Ella J. Harris, original owner of the Harris Building and the first woman to vote in Oregon following the granting of suffrage in 1912.
