Interior designer Ally Coulter has put her Greenwich, Conn., home on the market for $3.98 million.

The 19th-century, five-bedroom home at 55 Byram Shore Road was renovated by Coulter, the former creative director for Fendi Casa.

Built in 1896, the 4,700-square-foot home opens to a large foyer with 20-foot ceilings and a gallery with nine original stained-glass windows.

There’s also a library with a fireplace overlooking Greenwich Harbor, a formal dining room with water views, a chef’s kitchen, a third-floor “reading annex,” a gym and a main bedroom suite with a fireplace overlooking Long Island Sound and Huckleberry Island.

The listing broker is Robin Kencel, of Compass.
