The Ritz Plaza seeks a new suggestion for up/down duplex townhouses that preserves quality of both urban spaces and private dwelling, while giving back the city a pleasant environment. The project groups the more intimate areas of two up/down units on to the second and third floors in order to avoid unwanted disturbances from the neighbors. The ground floor is purposefully raised to redefine the urban public-private edge, and at the same time to visually connect the garden of the lower unit with the parks.
