The history of the manor starts from the 1540s. The main building is from the early 19th century, it was built by Carl Johan von Numers. From 1857 the manor was owned by Pavel Sinebrychoff. In the 1920s it was transferred to Arne Grahn, nephew of Fanny Sinebrychoff, widow of Pavel Sinebrychoff's son Paul Sinebrychoff. In the 1950s the substantial lands of the manor were converted into a residential area, which later formed into Tapiola and part of Otaniemi.
