The design of the DeVille's house is very similar to the Pickles' house next door, but unlike the Pickles' house it has a true mansard roof but flat top topped where the top of the roofline extends, and is slightly taller and narrower, and has a chimney mounted within the structure of the house. The walls are yellow and the roofings are a burnt orange. The garage, unlike the Pickles' house, is a lean-to.
It has green carpets and a basement. Phil and Lil's bedroom has two cots next to each other and appears rather fancy. There is a houseplant near the telephone.
