The building stands nearly midway between the park's road ring and the lake. It is surrounded by 4 acres of gardens. Although the house appears to consist of two stories, there are actually three, the offices being contained in a basement. The entrance is under an Ionic-style portico and pediments. It has a bow or rotunda decorated by four columns; the bow is surmounted by an attic, and is covered with a well-proportioned cupola. Renovations occurred in 1911 with the addition of wings by Bertie Crewe and again in 1935 when a balustrade replaced an existing dome.
