The idea behind these kitchens is to keep families together, even when various family members come in different sizes, shapes and ability levels. So, instead of a one-kitchen-fits-all model, Bilyeu offers kitchens that can serve dual needs.

"Many times, older folks are moving in with their children," she said. "They need to be accommodated so a family can work together."

To that end, her showroom features a standard kitchen with all the accessories, and a second one designed around an island with a sink that is easily accessible to those with special needs.

The showroom also features two full bathroom displays as well as three smaller versions, incorporating a variety of Universal Design options.

Her firm works to provide everything needed to take care of the job from start to finish. She notes that the firm employs its own union carpenters who are experts at installing these specialty items in her clients' homes.

Her next showroom project, she adds, is an attempt to reach young people at the other end of the aging spectrum. Accordingly, Bilyeu is putting in an accessible display to get kids interested in working with their parents in the kitchen. It will feature a little microwave suitable for a child to operate. "It's a niche market that has not been explored," she says.

Most of her promotion is done through referrals. She does some special promotions through the mail, sending out postcards and brochures to prospective clients and established customers, she adds. Also, her Web site, www.lastingimpressionsremodeling.com, offers examples of common Universal Design adaptations.

While some of her designs require extensive planning, many Universal Design adaptations are relatively simple. For example, she notes that some of the design changes most frequently needed in the kitchen involve raising the dishwasher, lowering the microwave and creating seating possibilities at the sink and cooktop. For bathrooms, Bilyeu says taller commodes are often needed, as well as seating areas in the shower.

Sometimes, shower floor surfaces and entryways must be made wheelchair accessible or safer for those with limited mobility. However, slip-resistant flooring is a good choice for everyone, she adds.

Throughout the home, Bilyeu also suggests adding extra lighting and replacing carpets and area rugs with hard floor surfaces.
