Olga Binary became acclaimed mainly by her residential building designs. These houses on Hankoczy Street had a well-organized plan, and a very compact spatial organization. In the building itself there are average size flats, three per floor: two smaller apartments with a loggia and a large one with two loggias at the two sides. The housing floor plans reveal order, edited unit. The functional layout and space management are key elements of the design. The generous spatial relationships made the apartments' atmosphere much more spacious.
