DC Design House, April 14 – May 12: The Washington, DC Design House began in 2008 as an event for the D.C. Metro area in which top area designers showcased their talents into a “flowing design home” to raise funds for a local charity. What began as a single event goal to raise funds for Children’s National Medical Center has developed into the region’s foremost annual residential design attraction and as a leading annual fundraiser event for Children’s National Medical Center.

Lake Forest Show House and Gardens, April 27 – May 19: A spectacular David Adler estate has been chosen as the 2013 Lake Forest Show House & Gardens.

All proceeds from the show house will help to fund the Angel Harvey Infant Welfare Society of Chicago Community Health Center, located in the Logan Square community. Shuttle buses will pick vistors up at 1150 North Western Avenue, Lake Forest, Illinois and transport them to the show house.
