Historic Structures

Quadrant Design is a leader in the renovation and preservation of historic structures.  Welcoming the challenges faced when adapting and remodeling existing buildings, our staff has experience including "down and dirty" renovation projects which saved structures from demolition court as well as highly publicized preservation projects which meet extensive public scrutiny.  Project experiences include building envelope restoration & repair of 19th century brick buildings, preserving log cabins, historically sensitive repair of historic wood structures, adaptive reuse of mid-century concrete structures, and facade restoration of early 20th century landmarks carried out under tax credit requirements.  Quadrant Design has renovated a 115 foot tall cross, and the cross atop a 200 foot steeple.  We have preserved the foundations of large historic structures and designed new foundations for a one-room schoolhouse which was moved 15 miles to become a museum.

We have knowledge of local, state and national regulations including the "Secretary of Interior's Standards for the Treatment of Historic Properties", "Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings", "The International Building Code for Existing Buildings", and the ADA Standards for Historic Structures.  Quadrant Design clients have successfully received Missouri and Federal Tax Credits.  Others have made their historic properties economically viable through Energy Efficiency Upgrade Grants.
