the lift a drawing set

A former professor and friend of mine approached me to create a set of drawings for an addition to a house he designed in the 70's. He designed the house for a cousin who is now in her 80's and needs a new entry stair to facilitate her mobility and accessibility needs. The house is located on the coast in New Jersey, requiring the main living space to be a full story above ground (in turn requiring a lift when the resident ages). I was provided sketches and translated them into a 3D model and traditional architectural drawings to ensure the design of the house was not negatively impacted by the addition of a lift.
