a house with a hall

Plan as generator (aka, ‘floor plan comes first, elevations second’), with a long hallway bisecting a semi-cubic volume, colonnades at either end.  Now a staircase – centered on the hallway, one half of the house takes a large ballroom, while the other is bisected into two smaller drawing rooms. The second floor, two long, windowed rooms sit over the porches, while a tall pyramidal skylight tops the stair hall.
