Architect’s haven is a project of a single family house with office, located on Old Danube in Wien. This place combines „big city” life style with close contact with the nature. Unique topography and size of the site were inspiration to partialy overhang the house above water surface. Transportation potential of the river gave us an idea of transforming typical office room into a mobile, floating barch and let the house be a safe dock. Giving to architect possibilty to flow, search for inspiration or meet with a client in outstanding surroundings. This solution ensures perfect division of private and professional life and proves that haven could be heaven in the same time.
