This building has different design based on the concept of vertical building. This, the vertical and architectural pinnacle of the Butler House, fills the void that affects so many inner-city dwellings – a lack of outdoor space. This building will be suitable for the people who like house that has outdoor facilities. The indoor and outdoor space of this house is really wide. An adjustable vertical spine was fashioned from floor to roof, creating a flexible isolation between levels. The roof also lets the solar enters the room to make the room warm and healthy. A traffic-able glass floor on the roof, next to the spiral staircase, allows a visual connection and solar access to the living areas below. All the windows are glasses to enjoy the view from inside. The existing mezzanine floor was somewhat of an acoustic pitfall within the house. Used primarily as a rumpus room for the children. The living room is very wide and completed with good furniture. The kitchen, which had previously felt shoved into the corner, was now defined and connected. The kitchen is also wide with good stove system.
