This design is a two story addition to a city house.
It was owner built, with great savings from using
doorwall replacement glass for the fixed windows,
and basement sashes as lower operable windows.
The upper, master bed loft has an open ceiling,
with halfwall balcony overlooking the glass wall.
The lower family room, has a brick paver floor.
It is also well insulated, with 12" in the ceiling,
and 8" in the walls. Note the insulating shade.
The glass wall has 4x6 posts and beams. The
lower ceiling is also big beams and wood.
