The most well known area of Roundhay is Roundhay Park. In the thirteenth century it was a three square mile hunting park for the DeLacy family of Pontefract Castle. Roundhay Park comprises over 700 acres (2.8 km²) of parkland, lakes and woodland. The Park includes scented gardens for the blind, National Plant Collections, Canal Gardens , the Monet and Alhambra Gardens , in addition there is Tropical World which attracts visitors all year round. Roundhay has a wide variety of housing. There is a large mixture of Victorian through terraces, villas and twentieth century detached and semi detached housing. All of the housing in Roundhay is privately built, the nearest council housing in on the Lincombe Estate in neighbouring Gledhow; unlike many council estates in Leeds , this has a favourable reputation and house prices are high. Because there has never been any mass house building in Roundhay at any one time, there is no consistent style throughout the area. Roundhay is perhaps the most expensive area for houses within the Leeds Outer Ring Road.
