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.

What do the Terms Mean?

Preservation focuses on the maintenance and repair of existing historic materials and retention of a property's form as it has evolved over time.

Rehabilitation acknowledges the need to alter or add to a historic property to meet continuing or changing uses while retaining the property's historic character.

Restoration depicts a property at a particular period of time in its history, while removing evidence of other periods.

Reconstruction re-creates vanished or non-surviving portions of a property for interpretive purposes. 

Adaptive reuse is the process of re-purposing an existing building for a purpose other than what it was originally designed for. The building may or may not be of historical significance.


You might find us on a scaffold, a lift or a bucket hanging from a crane to survey your existing building. Gathering information helps us narrow the unknowns and define the project’s scope.
