The first inhabitants and the Gräsa manor The medieval village of Gräsa was located on both sides of the
Gräsanoja stream in the Olarinluoma area around the current
Olari church. In 1540 the village consisted of two houses and a
frälse, which had been founded in the previous century between 1450 and 1460. The old lot and the buildings of the
Gräsa manor were located on a hill to the east of the Gräsanoja stream, which was still suitable for water transport at the time, at the site of the current Olari church. The Gräsa manor was originally one of the most significant manors in Espoo, and it was called "the old
frälse" of the area. The manor was known as Haldensböle after the man named Halden who controlled it in the 15th century. It is also known as the Olarsby horsestead. By the start of the 17th century, the houses in Olarsby had been annexed to the Gräsa
seat farm. For almost its entire history, Gräsa was controlled by the
Hammarstierna family. The
frälse was revoked in 1683 and the manor became a horsestead. Gräsa changed owners repeatedly starting from the late 18th century. Landowners in Espoo founded many new croft houses on their lands in the 18th century, which were supported by tax relief. Construction was further increased by the lack of workforce caused by the wars in the early 18th century. The large main building of the manor was built in the 19th century and was thoroughly repaired in the early 20th century. The manor had a large courtyard, containing economic yards and a large garden, which contained 45 different species of fruit trees according to a 1936 survey.
Land parcelling and construction in the early 20th century The rapid growth of the population of Helsinki and the construction of the
Rantarata railway also caused the population of Espoo to increase in the early 20th century. The growth was mostly located near the new railway connection, as transport connections between southern Espoo and Helsinki were still weak. Travel to Helsinki from the Niittykumpu area was by train or bus, but as the area was not near any major traffic hub, people first had to go along local streets to the train station in
Kauniainen or to the bus stop along the Turuntie road in
Kilo, and from there onwards to Helsinki. when many new terraced houses were built in the area because of rapid growth of Espoo. New construction was partly done on unbuilt lots, but there were also cases where old villa buildings were demolished to make way for new construction. Complementary construction of the metro station started in autumn 2012, when
Skanska started the construction of the new Liberti residential block in the area between Merituulentie and Länsiväylä. At the start of the Länsimetro construction, Niittykumpu was only supposed to have a preliminary reservation for a metro station, but in October 2013 it was decided to build a full-scale metro station in Niittykumpu, as postponing the construction would have caused the cost of construction of the station to double. Construction of the metro centre started in March 2014, and it was opened to the public three years later in June 2017. As well as the metro station, the metro centre contains the shopping centre
Niitty and the apartment buildings
Niittyhuippu and Niittytori, of which the former has 24 floors and the latter has 12 floors. When the 90-metre-high Niittyhuippu building was completed, it was one of the
tallest buildings in Finland and the tallest apartment buildings Espoo. The old shopping centre
Niittytori was dismantled in late summer 2017, and a new apartment building block was built in its place. The immediate surroundings of the metro centre, the Liberti block and the apartment buildings along Haukilahdenkatu, part of the first construction phase of the Länsimetro project, were completed in the early 2020s, when complementary construction of Niittykallio and Merituulentie. The complementary construction of the former
Outokumpu office area had reached planning stage. The gas station in front of the Olari church will be dismantled and replaced with a paved Gräsanaukio square, with an underground parking garage for connection transport to the metro station and the church built underneath it. The automobile dealerships Länsi-Auto, Toyota Espoo and Delta will also be moved out of the way of the new apartment buildings. The population of the district is expected to double by the year 2025. ==Services==
