Tapiola, established in 1951 and located west of Helsinki, is a planned suburb designed by a number of prominent Finnish architects including Alvar Aalto. Much like Howard, this group of architects believed there to be a functional limit to both the area and the population of the city, and so the suburb was planned to house 26 residents perf acre and no more than 15,000 in total. The suburb, planned to be self-contained, was also designed to accommodate a range of income levels, mixing various types of residential units and building densities. Today, Tapiola serves as a reminder that planned suburbs are not necessarily always monotonous, single-class entities. Instead, they can represent experimental ways of living — together and with nature.
