This article reviews the impending auction of the Roslyn estate’s historic carriage house in Lancaster Township. Built in 1896 and designed by renowned architect C. Emlen Urban in the Châteauesque style, the two-story, 4,000-square-foot structure has endured years of restoration after a dramatic collapse. It is now offered to a new steward for adaptive reuse.
As a property on the National Register of Historic Places and holder of Lancaster County’s Level I Historic Site designation, the carriage house is where architecture, engineering, and preservation meet in the market.
A Storied Architecture: The Roslyn Carriage House
Situated at 321 N. President Ave., the carriage house represents late-19th-century estate design with distinctive massing and masonry. The exterior showcases Urban’s design, while the interior is currently a shell awaiting a new plan for adaptive reuse.
Architectural Significance and Style

The structure’s subdivision from the main Roslyn mansion adds complexity to its conservation. Careful material documentation and restoration decisions are essential for future adaption.
From Neglect to Stabilization: The Bowser Renovation Journey
Purchased in December 2019 for $325,000, the property had fallen into neglect. The grounds were overtaken by bamboo, and trees were dying from years of exposure.
The Bowsers invested in landscaping and began renovations. On Christmas Day 2020, a structural failure collapsed the back wall during excavation for a basement addition.
A multi-year effort followed to stabilize and reassemble the historic structure. The goal was to prepare it for long-term preservation and reuse.
Engineering Feats and Stabilization
To secure the structure and honor its history, substantial reinforcement was installed. Most original stones were reused, and replacements were sourced from Indiana to match the historic materials.
A polymer injection system was used for stabilization, requiring about 10,000 holes drilled into the floor and foundation. Now, exterior and foundation work are complete, and the interior remains a shell ready for adaptive reuse.
