Department of the Interior Headquarters Building, 1935, Washington, D.C., Architect: Waddy Wood Photo courtesy of HABS/Library of Congress

Constructed in 1935, the DOI Headquarters is a National Register-listed building in Washington's monumental core, near the National Mall. The building had 1,488 original wood double-hung, single glazed windows. New interior storm windows were installed for energy conservation and security (for blast resistance). The phased project combines repair and replacement in kind to reduce costs. Advantages of combined repair and in-kind replacement:

• Lower initial and life cycle cost than repair alone.
• Preserved original materials on main (E Street) facade, thus maintaining historic integrity.
• Replacement windows are located on a secondary façade.
• Original one over one, wood sash construction allows authentic replication.
• For future phases, the choice of repair versus replacement is to be determined, based on costs at time of construction.

Disadvantage: somewhat higher lifecycle, long term cost

With over thirty-five years of experience in manufacturing custom hardwood doors and windows, Artistic's goal is to create top quality, long lasting, durable windows which are remarkably elegant. Quality work combines quality materials and highly skilled craftsmen, both of which are common components in Artistic's 40,000 square foot plant with high-tech state-of-the-art equipment. We have produced windows of every type and size from the contemporary to the historical.
