Established in Philadelphia in 1999 under the name of S. Harris & Co, the firm has grown to five full-time and one part-time professionals in the disciplines of architecture, engineering and historic preservation.  In 2009 we incorporated under the name of S. Harris Ltd. and work out of an office of our design in the Fairmount section of Philadelphia. 

The entire staff is LEED certified as we are committed to the notion of sustainability as much we have been to preservation and conservation, all of which we see as essentially the same concept applied in various vocabularies.

"The 'greenest' building you can have may be the one you already occupy."  S. Harris
