Suurniemi became Karjalohja's studbook estate in the 18th century, although this one-house-village has been mentioned in tax records as early as the 1620s. Ever since the 17th century, permanent habitation has been in the area. For example, in the 1680s, Matti Heikinpoika from Suurniemi was in Karjalohja and Pohja's winter councils to sort out horse-related matters. The Karjalohja's vicar Isaac Florin bought the Suurniemi estate at the end of the 18th century and the family settled in Suurniemi.
During the 1870s, the first summer residents occupied the estate after the Florin family gave it up. This was followed by Suurniemi villa season, which continued for 75 years. During this time, the place functioned as a summer resort. During the spring, the holidaymakers arrived by train to Kirkniemi Station, where they continued by boat to Karkali. It was easy to walk over the narrow bay of Karkali, and this was followed by another boat to Suurniemi. The carriageway was only a bit wider than walking paths, so the lake was the fastest way to commute. Farm hands maintained the estate during winter times since the gentry pulled back to the city when autumn arose and the weather got chilly.
