PRESERVING LANDMARK ARCHITECTURE AT WOOLSEY HALL

Our restoration approach respected the monumental scale of this distinguished Yale University landmark. By carefully restoring the historic windows, we preserved the grand atmosphere and ensured that natural light continues to illuminate this breathtaking interior for generations to come.

Steel Window Restored to Structural Integrity

Damaged glass was replaced and the original steel frame carefully repaired to preserve its historic character. The restored window retains its authentic proportions while delivering renewed strength and lasting protection.
