While the building has a rough appearance today, the architecture is of a Palladian design. The upper floor consists of a hall and two reception rooms. On the eastern side, there was a third, timber-floored, level where the sleeping quarters were located. On the ground floor is a kitchen, servants' quarters and stairs to the upper floors. The entrance, which is on the upper floor, was reached by a long flight of stairs which is now missing. At each side of the building is a room with a lean-to roof which may have been used to stable horses. A stone mounting block to assist people onto their horses can be seen on the eastern side. To the front there was a semi-circular courtyard, enclosed by a low stone wall and entered by a gate. The house faces to the north, looking over Dublin and the plains of Meath and Kildare, including Conolly's primary residence at Castletown House in Celbridge. The grounds around the lodge consisted of a deer park. The identity of the architect is unknown: the author Michael Fewer has suggested it may have been Edward Lovett Pearce (1699–1733) who was employed by Conolly to carry out works at Castletown in 1724.
