Dib's House is the home of Dib, Gaz, and Professor Membrane. It is a large, rectangular gray structure which is distinguished from its neighboring houses by the electrical pylons lining its front walkway (The unfinished episode Return of Keef would have revealed that this actually is a security system; Dib mentioned it to Keef over the phone before finding him in his bedroom). The interior is a dark blue-green, and, at night, the windows emit a soft, green light from within. Dib is occasionally seen on the house's roof, observing the skies and listening for alien activity. The residence is located a block or two away from Zim's house. The Membrane house was redesigned in the second season to give a more futuristic appearance.
