It is situated on the northeast shore of the Lullwater, a waterway north of Prospect Park's Lake and southeast of the Ravine.

The classical design contains an arcade facing the Lullwater, with a canopy supported by columns of the Tuscan order.

The entablature at the top of the columns contains triglyphs, and a balustrade runs atop the canopy, surrounding it and forming a second-floor terrace.

After twenty years as a visitors center and park ranger headquarters, the Boathouse was restored for a third time in the late 1990s because of deterioration in the terracotta.
