Zimmerman House / Severna Park, MD
A Colonial renovation
Constructed in 1769, this colonial home was originally a comfortable farm house, but after 200 years, most of the original windows had rotted, warped and loosened. Like most windows of the colonial period, the windows lacked weather stripping and were made with standard float glass, wavy with imperfections.
The plans called for replacement of all the windows with new windows that replicated the original style and delivered maximum energy efficiency.
