New Design in an Existing Context

Page & Turnbull’s Architecture Studio provides design for existing buildings as well as new structures. We work both as architects of record and consulting preservation architects, always inspired by context. Our design philosophy centers upon imagining change: compatible change, balancing stewardship, flexibility, and long-term durability for new designs and historic rehabilitations alike.

We understand that each building will have its own set of physical conditions, and that any new design will be informed by our client’s goals, user group preferences, and of course potential cost. We often collaborate with our other studios to deliver a complete and holistic approach. We emphasize open communication, strictly defined schedules, and transparent project management in our projects. With these strategies, Page & Turnbull has been fortunate to obtain much of our work from repeat clients or recommendations.


It is more sustainable to preserve, rehabilitate, and restore an existing building, reusing the embodied energy and materials of that structure, than to start anew. Page & Turnbull has always placed environmental and social sustainability at the core of its practice, and we are constantly adjusting our services to produce sustainable and resilient design. With climate change upon us, we prepare our buildings not only to minimize impact on the environment from the outset, but to withstand harsher environmental conditions if they appear.
