Building a Handicap accessible Bi-level House

The objective here was to create a Bi-level house of approximately 1350sq feet with wheelchair access via a ramp down the right side to a lower deck and a 3 position built-in lift off the front entrance. Washrooms, kitchen, hallways, doorways would be done to facilitate use of wheelchair or walker throughout. Due to lack of available contractors it was decided to do a PWF foundation which could be done without a large contractor involvement.
