Architects propose simulated divided light windows for historic building renovation

The Harrisburg Architectural Review Board convened on April 7, 2025, to discuss significant updates regarding the renovation of a historic building in the city. A primary focus of the meeting was the proposed installation of insulated windows featuring simulated divided lights, which has raised public interest and concern.

During the discussions, representatives clarified the design of the simulated divided lights. These windows will include a raised mutton bar on both the exterior and interior faces of the glass panes, along with a divider between the panes. This design aims to replicate the appearance of traditional divided light windows while ensuring that there is no visible light gap between the interior and exterior components. The team emphasized that the windows are designed to maintain the building's historical aesthetic while incorporating modern energy efficiency standards.

The board also addressed the functionality of the windows. Although the original windows were operable, the new design will feature fixed double-hung windows. This decision was influenced by the introduction of HVAC systems in the building, which eliminates the need for operable windows for ventilation. The representatives noted that the operable windows were historically necessary for airflow, but with air conditioning now in place, this feature is no longer required.

In addition to the window discussions, the board reviewed the roofing plans for the building. Based on historical photographs from 1907, the team proposed reverting to an architectural asphalt shingle roof, as there is no evidence to support the use of metal or slate roofing materials in the past.

The meeting underscored the balance between preserving historical integrity and adapting to modern building standards. As the renovation progresses, the board will continue to evaluate design elements to ensure they align with both community expectations and historical accuracy. The next steps will involve finalizing window designs and roofing materials, with ongoing public engagement to address any further concerns from the community.
