Pihlajamäki is a so-called “forest district” of Helsinki that celebrated its 50th birthday in 2012. The rugged nature here is characterised by its rocky and forested hills with small valleys in between. The Vantaanjoki river flows along the western edge of the district. Along the river there are both forested areas and open farmland. The attractiveness of Pihlajamäki lies not only in its natural environment, but also in the tiny details of its buildings. Most of the architecture is modest and refined. The buildings are situated naturally according to the terrain. Pihlajamäki is indeed a model suburb in terms of both is modern town planning and architectural values. It even features the first modern architectural heritage trail in Helsinki, the Pihlajamäki Architecture Path, which was financed as part of the Neighbourhood Project. A historical protection plan is being drawn up for the entire Pihlajamäki, which was developed in the 1960s. The natural parks and environment would be protected within the framework of the same plan. Pihlajamäki is home to around 7500 residents. The green areas in Pihlajamäki can be rightly referred to these days as “retro parks”. The parks consist mainly of forests, rocks and ponds that man has respectfully and carefully modified to make them more sustainable in terms of both wear and functionality.
