In Teton County we limit bulk and scale by limiting habitable floor area. We define habitable floor area as:
"Habitable floor area is floor area used for living purposes, usually having access to heat, plumbing, and electricity. It includes foyers, hallways, restrooms, closets, storage, and other common areas within a building. Habitable floor area does not include mechanical rooms, elevators and fireplaces. Habitable floor area is measured either from the exterior of the faces of the building or the exterior limits of any interior wall that separates habitable floor area from nonhabitable floor area, whichever is applicable."
Obviously, people are always pushing the envelope, and I received a set of building plans that have a large window that is almost floor-to-ceiling, except for a rise of about 18" off the floor. Normall, we consider this "window" to be habitable floor area. However, the architect is challenging us because it puts his client's house beyond the threshold allowed by the restriction in habitable floor area. He is calling it a bay window, so I'm searching for definitions regarding what is a bay window.
Anyone out there have a definition of what is a bay window? We are looking for criteria, such as: how high off the floor? how large of a window opening? and how far our can it project (depth of the window sill)?
Thanks for any insight.
