The development of Tapiola occurred in several stages: the eastern neighbourhood 1952 – 1956, the western neighbourhood, 1957-1960, the town centre 1958-1961-1970, the northern neighbourhood 1958-1967, the southern neighbourhood 1961-1965.<ref name="armen"/> Planning in Tapiola commenced with architect, Otto-Iivari Meurman's site plan and building schedule which were reviewed from 1951 onwards.<ref name="tuomi_paatero"/> His original plan detailed four neighbourhoods split by two crossing roads and set apart by green belts.<ref name="hertzen_spreiregen"/>

Architects Aarne Ervi, Viljo Revell, Aulis Blomstedt and Markus Tavio were charged with designing the eastern neighbourhood based on Meurman's plan.<ref name="tuomi"/> They were required to design buildings suited to the surrounding environment and the topography of the area.<ref name="hertzen_spreiregen"/>

A housing team was created to appraise the architects' housing designs; this process occurred more frequently during the development of the eastern neighbourhood.<ref name="hertzen_spreiregen"/> Team members were from a wide range of fields and included a building engineer, a heating engineer, two independent architects, an electrical engineer, a landscape gardener, a domestic science expert, a child welfare expert, a sociologist, and a housewife.<ref name="hertzen_spreiregen"/> This unique team, coupled with the board of the Housing Foundation, assessed housing designs, taking into consideration the needs and desires of future residents from a diverse range of backgrounds.<ref name="hertzen_spreiregen"/> The parties had different beliefs and values, which sometimes led to disagreements, for example the Housing Foundation was concerned with economising whilst the home-economics experts were chiefly concerned with the needs of families.<ref name="tuomi"/> Thus planning in Tapiola was collaborative and proactive as it involved targeting specific family types and classes, deciding on an ideal lifestyle for these residents, which accordingly influenced their behaviours.<ref name="tuomi_paatero"/> Many dwellings were designed to house a specific family-type and lifestyle.<ref name="tuomi_paatero"/> For example, it was perceived to be ideal to have families with children reside in dwellings, at or close to ground level in order for the children to have better access to the outdoors and to parks, whilst a tower block with one-room flats was designed to accommodate childless couples.<ref name="tuomi_paatero"/>

Meurman resigned from the board of governors of the Housing Foundation in 1954 following a shift from developing a town with low population density (six persons per acre) and low-rise buildings dwellings, as advocated by Meurman, to more multi-storey buildings and a higher population density (30 persons per acre) as recommended by other architects and the Housing Foundation.<ref name="tuomi"/><ref name="hertzen_spreiregen"/> This shift was prompted by the need to accommodate a larger population, triggered by the housing shortage in Finland.<ref name="tuomi_paatero"/> Ervi took up Meurman’s position as master planner.<ref name="lahti"/>

The development of the eastern neighbourhood led to the implementation of important planning principles such as providing facilities that encourage interaction and foster a sense of community as well as the separation of vehicles and pedestrians.<ref name="hertzen_spreiregen"/> It was also deemed necessary to have a mixture of building types located within the one area to encourage social diversification.<ref name="armen"/> The eastern and western residential areas of Tapiola featured curved streets of varying sizes and positions, whilst the northern neighbourhood designed by architect Pentti Ahola, marked a return to the orthogonal grid plan.<ref name="tuomi_paatero"/> Ahola's design however, reflected the original aims of Tapiola; that of encouraging social diversification by locating a variety of building types within the one area.<ref name="tuomi"/> Financial concerns affected the development of the western area of Tapiola, leading to the construction of housing units that were economically feasible.<ref name="tuomi"/>

In 1953 Aarne Ervi was awarded the commission to plan the town centre.<ref name="lahti"/> The aim of the town centre's design was to provide all the facilities necessary for a modern urban centre and to maximise social interaction.<ref name="tuomi_paatero"/> The centre included a market square, public square, church, public premises, businesses and an administration building.<ref name="tuomi"/> As with the other areas of Tapiola, the centre was designed with consideration for the site's features and terrain as well as to provide an active and versatile environment for pedestrians.<ref name="tuomi"/> Roads surrounded the central area producing a modern design completely separate from vehicles and featuring a special route for pedestrians and cyclists only (Tapionraitti).<ref name="lahti"/> Ervi ensured the centre preserved the garden-city character of Tapiola by locating the buildings around an artificial lake, however this plan was considered strange and criticised for its lack of density.<ref name="tuomi"/> The centre was later expanded with a pedestrian based shopping centre linked to the Tapionraitti, notable for its undercover, outdoor pathways.<ref name="tuomi"/> Later developments showed less consideration for the natural surroundings, though most developments respected the dominance of the existing buildings.<ref name="tuomi"/> Tapiola's centre did not expand to such an extent as to rival Helsinki.<ref name="tuomi"/>
