Chian-Ian Kuan is planning to target these trouble-spots in a near-future remodel so she can go on living in her postwar Torrance home as she ages, no matter what hurdles her twilight years bring. “Right now I’m OK, but I want to be able to live here as long as I can and as long as it’s safe,” says Kuan, an effervescent 57-year-old social worker hobbling around her house with a sprained ankle on a recent afternoon while sharing her vision of universal design – attractive, well-thought-out spaces that allow people at all stages of life to comfortably move about the same house.
