I promised to care for my mom with Alzheimer's. I'm building a tiny home in our yard instead of choosing a care facility.

Lena Koropey is building an accessory dwelling unit (ADU) in her backyard to care for her mother with Alzheimer's, following family tradition. She purchased a home in Mattituck, New York, which includes a three-bedroom ranch-style house with a half-acre lot to accommodate their needs.
