Elevating communities and places through thoughtful design.


Landmarks SGA, LLC, an affiliated company of Stromberg/ Garrigan & Associates, was established to offer specialized architectural services focused on new design, adaptive reuse, and preserving historically significant structures. Our work primarily involves urban revitalization, sensitive infill architecture, and repurposing existing structures, as well as building condition assessments, historic structure reports (HSRs), and upgrading structures to meet current building, fire, and ADA codes. We have received numerous awards for our historical preservation projects, some of which have been recognized by Preservation PA and provided services on sites located in 12 states.

Landmarks SGA is based in Pittsburgh, PA, with a regional office in Jenkintown, PA (metro-Philadelphia). Our team of professional architects and preservation specialists employs a comprehensive and multi-disciplinary approach to projects, aiming to maximize a project's full community potential with the highest level of creativity. At Landmarks SGA, we encourage communities to identify and leverage their assets to achieve economic redevelopment and physical enhancement.
