We are building a handicapped accessible ranch house

We are building a new house that will be completely handicapped accessible for Andy. There will be a handicapped ramp on the front of the house. There will be wider hallways and doorways. Andy's bathroom will be like a wet room with a roll in shower and tub next to it. We will have an open concept kitchen and living room, and a playroom/office over to the side. We are building a garage big enough and tall enough to hold a tall full sized handicapped accessible van, plus other cars.

We've been picking out building materials, and I've also been trying to organize and consolidate things here at home, and study when I can. It's been busy. I'm definitely worn out.
