The compartive sizes of the new structure and the existing house is skewed in this image because the addition is moved forward from the west face of the house.
A section through the new structure, showing the two car garage below, and large open space above. The space to the left of the sink is the stairway up from the ground level.
The sixteenth inch scale model shows how the addition was positioned to try to block as few existing windows as possible. The small windows on the east facade match the small square windows on the existing house.
The sixteenth inch scale model with the roof removed. The Bedroom is to the right with the Bathroom open behind it (just the toilet is enclosed). The main Studio space is to the left.
