This would be just one floor of a classic NYC brownstone townhouse! Theres super dark furniture and decor to contrast with the bright light that comes thru the floor to ceiling windows! The other half includes the kitchen and dining area which has a view of the back yard patio area!
Here you can see the division between the front area and the stairs, with the back kitchen and dining area. The two areas are divided by a single brick wall which has openings on either end of the wall to add easier flow between the spaces.
