Design the facade and interior of a to-be-built townhouse on West 122nd Street in New York City. The building is to be six stories. The street level will have a public lobby at the front of the building and the first floor of a duplex apartment at the rear of the building. The duplex apartment will also utilize the rear of the ground level and will include two bedrooms, two baths, laundry facilities and access to the back yard. There will be three identical two bedroom, two bath apartments on floors two through four. Floors five and six are to be used as the owners duplex and should include three bedroom, three baths and laundry facilities. The owners would like to accommodate a baby grand piano in their living room and would like a well designed fire place wall as well.
