About Us

With over 30 years of experience in the architectural field, David Saint-Jacques of dsjDESIGN brings a unique and valuable blend of expertise and experience to his valued clients. The office of dsjDESIGN takes responsibility for all project phases from client relations to conceptual design, and construction documents through construction administration. David has a substantial amount of experience in all phases of project management and design. Founded in 2004, dsjDESIGN has been involved in the development and execution of over 25 residential projects in the Sewickley area, over 45 in the larger Pittsburgh city area, and many more in other states including California, New Jersey, and New York. Residential projects include new construction, with the majority including renovation and additions to larger historic homes as well as designs for hardscaping and landscaping. Pittsburgh House Trends magazine has featured two of the firm’s residential projects. These were the cover stories for both the July 2009 and March 2011 issues. Before venturing on his own, David was a project architect with WTW Architects in Pittsburgh, and with Musgnug Architecture on Long Beach Island in New Jersey. David graduated from SDSU with a Bachelor Degree of Arts and Sciences with an emphasis in sustainable architecture. References available upon request.
