BHB provided MEP and structural engineering services for the new restaurant, 61 Osteria, which is featured at the First on 7th complex in Downtown Fort Worth. 61 Osteria is on the street level of a newly renovated bank tower that was converted into a mixed-use development. The new restaurant offers great views of Burnett Park due to its floor-to-ceiling windows and overlooks modern art sculptures on the outdoor patio.

The mechanical engineering side of this project was a bit challenging, dealing with the extreme solar load that comes with floor-to-ceiling windows that are single-paned with no reflective coating. The mechanical team needed to find a solution to this issue since the existing solution was no longer code-compliant. The mechanical team solved the issue by using floor-mounted chilled water fan coils that run air parallel to the window, and our team also supplied air from the ceiling down along the windows to mitigate the thermal discomfort of the sun coming through the windows.


The dining room and bar are conditioned by chilled water air handling units located above the kitchen ceiling. The kitchen is conditioned and ventilated by a dedicated outside air system (DOAS) located on the 3rd-floor roof. The ductwork for this unit was coordinated with the architect and building owner through two floors before it was able to be on the roof.

The electrical distribution side of this project was planned in early 2019 as part of a building infrastructure upgrade. This planned phased distribution allowed minimal disturbance of the areas that were finished out and easy integration for the new restaurant into the existing main building. Power to the space was coordinated to ensure it could be easily integrated into the limited back of house space to maximize function. The use of smaller transformers that could be placed above ceiling grid was key to maximizing the efficacy of space utilization. Lighting was carefully coordinated, modeled, and selected to provide a unique dining and bar experience while not only focusing on the patrons’ patio, dining, or bar experience, but also employees’ functionality and customization of lighting for many work spaces. Unique lighting scenes and highlighting of decorative art locations have been planned to allow for many experiences as one traverses through the entry to their final sitting location.


Structural design aspects included coordination with certain architectural features in the restaurant, such as large chandeliers in the bar and dining room and marble feature walls throughout the restaurant. Our structural team also had to ensure that all the new kitchen equipment and mechanical units could be supported by the existing structure that was not originally designed to host a restaurant.

This project is the winner of a 2024 AIA Fort Worth Honor Award.
