The O'Connell Residence is the O'Connell family's home. It first appeared in "The Simpsons Already Did It".
The O'Connell's House is built just like every other house in South Park with a garage. The house is a darkish gray color. There are five windows, probably for each of the main rooms in the house.
The only room that has been seen in the house is the living room, though there are most likely a bathroom, kitchen, dining room, and possibly two bedrooms. The living room has a purple carpeted floor with a orange single sofa next to a regular brown sofa with two orange pillows and a small table in-front of both, along with a television in-front of all of that.
