Arts and Crafts Bungalow "Treehouse"

Last year I purchased a two-story brick building in a small Kansas town.  The first level is your conventional, early 20th century commercial space with high tin-tiled ceilings, wooden floors and lath and plaster walls.  However the second story of this building that was built around 1930 has a floor plan that is an arts and crafts bungalow.  The living/dining room has a wooden arch and a gas/ceramic fireplace with a wooden mantle.  The windows are 3-over-1 double-hung.  Doors to two of the three bedrooms are French with glass inserts.  The kitchen is in its original location, but it has been modified.
