The project is an expansion to the clinic owner’s house above a pediatric dental clinic designed for the future development. The wishes of client were “open house with no partitions inside”. We omitted creating wall partitions between rooms necessary for a daily life and proposed different in levels floor plan in which space is divided by steps. When you enter the house there is a hall.Then, when you go upstairs you will see a room with a fire place.Next, when you go up, there is a living room.From there, you go up, you enter a dining room with a kitchen.On the upper floor, there is a bedroom.
