A couple of Davids from Pittsburgh's past and present will be among the highlights of the 27th annual Pittsburgh Home & Garden Show, which runs Friday through March 16.

A modern bathroom designed for former Mayor David L. Lawrence and a balcony apartment modeled after the home of actor David Conrad are two of six rooms featured in the ASID Designer Showcase. To mark Pittsburgh's 250th anniversary, members of the Pennsylvania West chapter of the American Society of Interior Designers are creating rooms reflecting how famous Pittsburghers might live today. The rooms will be located on the second floor of the convention center that bears Mr. Lawrence's name.

Nearby, visitors can ride on a Ferris wheel and see a display about the North Side home of its inventor, George Washington Gale Ferris. The Pittsburgh 250 area also will include a re-creation of the Crawford Grill in its heyday as a jazz club, with live music by students from the High School for the Creative and Performing Arts. Elsewhere on the second floor, local students will be performing songs from their musicals and Hollywood's version of "High School Musical."

Home show attendees also can tour the Blueroof Independence Module, a mobile unit that allows elderly or handicapped residents to perform daily tasks unassisted. The module is designed to be attached to an existing house and is filled with assistive and monitoring devices created by McKeesport-based Blueroof, other local companies and accessibility experts at the University of Pittsburgh, Carnegie Mellon and St. Francis universities. If the display of Universal Design intrigues you, stop by the Community Design Center of Pittsburgh's booth, where architects will provide free advice on how to improve your home or make it more handicapped-accessible.

The already "green" convention center will be even greener during the show, thanks to A-Maze-in-Green, an actual 3,000-square-foot garden maze where every turn teaches about environmentally friendly and sustainable techniques, design and technology. The first-floor exhibit is sponsored by Bidwell Training Center and the Post-Gazette.

With more than 50 groups represented, home show executive director John DeSantis believes it will be the biggest local gathering ever of "green" products, services and information.

"Everything related to the environment in home and garden will be there," he said.

Show hours are 4 to 10 p.m. Mondays through Thursdays, 10 a.m. to 10 p.m. Fridays and Saturdays, and 10 a.m. to 6 p.m. Sundays. Tickets are $10 for adults, $4 for children ages 6-12 and free for children under 6. Parking at Heinz Field is $5 with a free continuous shuttle between the lots and convention center.
