Contact us about your project

History is an ongoing story. We’re passionate about continuing it.

Some projects strive for a strict interpretation. Others strike a balance with modern amenities. Whatever yours requires, we’ll guide you through the process — from tax credits and grants to historic preservation standards. Our passion is restoring, preserving and rehabilitating buildings using the gentlest means possible. In the end, every project is a unique celebration that respects the past, serves the needs of current users, and creates a statement for future generations.
