Architecture: Historic Preservation, Renovation and Reuse

Celli-Flynn Brennan believes that our built environment is a valuable resource worth preserving.   Realizing that, we develop appropriate responses despite contemporary market forces and diverse client needs.  In fact, we have decades of experience in local and national preservation and reuse..  Our work also includes additions to historic structures that harmonize with the original architecture. 

  • The additions to the Pennsylvania State Capitol and to St. Paul Cathedral in Pittsburgh are very different in scale and function but both reference the landmark structures which anchor them. 
  • Sometimes a historic structure functions well but needs sensitive preservation for continued use.  The National Register-listed Main Building at Peace College in Raleigh dates from 1857 but still serves the College as its core -multifunction facility, representing for many the physical symbol of the school.
  • In other instances a structure requires interventions to adapt to changing needs.  At the Somerset County Courthouse, a new courtroom was created from ancillary space while existing courtrooms and offices were restored and enhanced with improved lighting, HVAC and technology infrastructure.
  • Our cooperative planning process helps clients discern the best response to the special needs inherent to continuing use of historic structures. This process is unfolding today at the Shadyside Presbyterian Church, an 1886 National Register building, and at McMillen Hall, a 1793 building also on the National Register, at Washington and Jefferson College.

Our planning process is aimed at reaching the best possible conclusion, whether a structure’s use remains the same, is adapted for current and future needs, or is changed entirely. We believe that restoring, renovating and adapting our historic structures is beneficial to both our clients and their communities.
