Of an era when even utilitarian structures were designed to please the eye and withstand the test of time, this imaginative and inviting Princeton residence began as the greenhouse of the Moses Taylor Pyne estate, now the NJ Governor’s mansion. Two large-scale renovations by the current owners were remarkably sensitive to the building’s roots. Architectural firms Holt, Morgan and Russell and Outerbridge Morgan preserved a certain humble air, while incorporating high-end finishes. The two renovations and addition substantially increased the footprint and raised ceilings exposing lustrous wood sheathing and industrial fittings from 1890. New materials seamlessly blend throughout, such as broad slate and heart pine flooring. Waterworks bathrooms are timelessly elegant. Wraparound windows give the master suite treetop views, while tiered windows in the gourmet kitchen look out over original greenhouse walls, now edging stone patios. Beyond the 1.54-acre fenced yard, sidewalks lead straight to the center of town.
