This project allows students to role-play, investigate and analyze the specific needs of a wheelchair user and relate those needs to the built environment – specifically the home and work environments.


Client Profile

Your client is a single mom with a 10-year-old son. She is a well-known, highly respected painter and illustrator, and recently purchased a charming bungalow built in 1928 to live in and use as a studio. She is also a wheelchair user that has full use of her upper body and is fully self-sufficient limited only by the need for the wheelchair.


The existing layout of the bungalow does not adequately meet the unique needs and abilities of your client, and requires renovation to operate efficiently. The final design should include the following spaces/rooms:
