Lauren Thomsen Design is an award winning architectural design firm based in Philadelphia. Our work is based on the fundamental belief in the value of space, and the ability of good design to enrich people's lives. We take on projects of a broad range of program and scale in the office, and work closely with our clients to understand context and to define the unique story of each project. We love not only the outcome, but the process of design, and it is our goal to make sure that our clients do too. Working holistically, we lead interdisciplinary project teams to deliver interesting, sustainable, and well coordinated design solutions through the use of innovative digital tools and our expertise in material and building systems. Most importantly, we recognize that our projects are not simply a built output that is designed, constructed, and then turned over to a client. We see our projects as ecosystems that must serve owners and occupants for their entire life-cycle, and embrace the responsibility to deliver the best possible design solutions accordingly.

LTD is a certified woman owned business with the WBENC and a Local Business Entity with the City of Philadelphia, and we are licensed to practice in Pennsylvania, New Jersey, and New York.
