| 1983 | Robert graduates from high school, he attends college math classes for a year before starting Cornell. |
| 1965 | Robert Whitehead born in Susquehanna, PA. |
| 1984 | Colin graduates from Stuyvesant. We meet in Ithaca, NY when we matriculate to a college of architecture. |
| 1987 | We design our first built project together. |
| 1988 | Other undergraduates get their degrees. Ours is a five-year program to get a Bachelors of Architecture. |
| 1989 | Classmates get their BArch’s, but we’ve each taken a year off. |
| 1990 | Cornell awards Robert his Bachelor of Architecture. We form Whitehead & Co. in Jackson, Pennsylvania. |
| 1991 | We build our first house as W&Co. |
| 1992 | Colin moves to New York City. There are fewer architecture opportunities than he had hoped. |
| 1994 | Colin moves to Las Vegas and starts designing The Slammer. Cornell relinquishes Colin’s Bachelor of Architecture. |
| 1995 | Construction starts on The Slammer. |
| 1996 | Colin moves to Los Angeles, CA. |
| 2001 | Colin accepts the commission for The Castle. It
is immediately clear that it is a huge, and daunting, task. Robert flies out for a four day weekend and we design the Calico House together. |
| 2002 | Robert moves to Santa Monica in May. The partnership allows for a couple simultaneous projects, including two in Los Angeles, CA. Robert starts studying for the architectural licensing exam. |
| 2003 | The Castle continues its slow journey through permitting. We take another few small jobs in Los Angeles to have work that doesn’t require a commute on Southwest. |
| 2004 | One of the small jobs in Los Angeles turns into a large job. We design two more additions to The Slammer. |
| 2005 | We start trying to get a little more local work, and even put up a web site. Colin gets licensed as a private pilot so our commute to Las Vegas is easier. |
| 2006 | The client moves into The Castle, The Slammer: Cellblock B opens, and we finish a job in
New York City. Robert is licensed as an architect in Pennsylvania. Colin gets his instrument rating, so we can commute through any clouds on the way to Las Vegas. |
