With baby boomers approaching retirement, universal home design takes on a new importance. Today, in part 2 of the ?accessible home,? we discuss better living through technology. Yesterday, we discussed commonsense design, but there are many new and exciting technologies that enhance a home's livability and value while benefiting the elderly and disabled, too. One example is a keyless front-door lock, either remote-controlled or using new fingerprint recognition technology.

New in-home residential elevators are now more affordable and practical, too. For more tips, visit our Web site at onthehouse.com. And that's the On The House tip for today.
