The 2017 DC Design House was the nonprofit’s last.

DC Design House Inc., a nonprofit that oversees the annual fundraiser for Children’s National Health System, has decided to disband. The effort has raised $2 million over 10 years — $290,000 in 2017 alone.

“We all want to proudly end the DC Design House on a high note for what we collectively achieved,” Skip Singleton, principal of DC Living Real Estate, said in a statement. “We are grateful for our all-volunteer staff working hard throughout the years to keep costs low in an effort to maximize our annual donation to Children’s.”

Singleton and his wife Debbie established DC Design House with Taylor Wells and the late Sandy Steele.

The annual effort generally involved top designers, about two dozen, showcasing their talents in a single home over the course of roughly a month.

The 2017 version included a daily cafe in the pool house, four boutiques in the five-bay garage and special events in the home’s ballroom. It was held in a four-story, 27,256 square-foot Potomac mansion with nine bedrooms, nine full bathrooms, four half baths, lower level ballroom, cinema, two-story library flanked by his and her offices, and multiple kitchens.

The Design House has been to McLean, Chevy Chase and, for seven of the 10 years, in D.C. In all, more than 90,000 people visited over the course of the decade.
