The firehouse is a three-story building, three
bays wide by four deep, on a half-acre (2,000 m2)
lot in downtown Tivoli. It is faced in brick laid in
English bond with contrasting stone
courses at the floor levels. The
hipped slate roof is pierced by a
dormer with
gabled
parapet top, four chimneys and a round
turreted tower rising from the southwest corner. The roofline's
cornice is broken in front by the dormer. On the northern (front)
facade, the first floor has two former garage openings, now filled with paneled wooden doors, and a regular entrance between them. The course above them consists of stone blocks with oak leaves, a traditional European symbol in
heraldry for firefighters. A
cornerstone gives the architect, builder and date of construction, and a marble
dedication plaque memorializes Watts and de Peyster. The stone
basement is visible along the side and rear elevations. Inside, the first floor is divided into the two large bays used originally for
fire engines, with plaster walls,
wainscoting, pressed tin ceilings and wooden-plank floors. The second floor, used originally as meeting rooms, has similar finishing as well as thin
cast iron columns in its largest room. All rooms have their original
carved mantel and fireplace cover. The third floor is a single large room with two large wood braces supporting the ceiling. There is one outbuilding, a garage built during the mid-20th century. It is not considered a
contributing property. ==Tivoli Bays Visitor Center of the Hudson River National Estuarine Research Reserve (HRNERR)==
