Watooka House is a three-storey early 20th century colonial building that started out as a privately owned establishment. During the early 1900s, it was renovated by the Demerara Bauxite Company (DEMBA) to accommodate its managers. In the 1940s, it was renamed Watooka House, the name Watooka originating from the nearby Watooka creek. The front façade of the guest house faces the Demerara River, whilst access can be gained from Casuarina Drive, Mackenzie.
Architectural features on the first and second floors include the wide overhangs, enclosed corridors on most facades, extended galleries, dormer and jalousied windows. The guest house has a pool which was once considered one of the finest in the country.
