Kaisankoti is a centre for rehabilitation, recreation, and vacation, maintained by the Kaisa Kallion Kansalaislahjasäätiö (a memorial charity dedicated to Mrs Kaisa Kallio, wife of President Kyösti Kallio). In addition to the main activities, the centre hosts a wide range of functions.
Located on a maple-covered hill in Pakankylä, Espoo, the centre prior to the extension included a Classicist, mansion-type main building (housing the reception, a dining hall, and a function room) as well as three separate pitch-roofed, board-clad buildings constructed in the 1980s. Of these three, the one closest to the main building housed a swimming pool and other facilities for physical exercise. The two other buildings were used for accommodation and various treatments. With the volume of activities expanding, separate buildings and lack of space became a problem, and in 1995 a decision was made to extend the centre.
The majority of the extension is situated between the exercise building and the southernmost accommodation building, which were thus connected internally. Moreover, both accommodation buildings were connected by a corridor.
The extension houses the reception, offices, and a lobby cafeteria, various treatment facilities (water and mechanical therapy, clay treatment), and appointment rooms for physicians and nurses. In addition, the building houses two gymnasiums, two conference rooms, and a therapy pool with adjacent steam bath and washroom. The nucleus of the extension is the high lobby, surrounded by the main activity areas. In addition to functionality, the visual connection from the various spaces to the surrounding nature was a central aim in designing the extension.
Adjusting the relatively large extension volume to the existing scale presented a problem. Consequently, the exercise facilities requiring high ceilings were almost entirely excavated into the slope, which helped in adjusting the partially slant-roofed building mass to the level of the existing buildings. An overall unifying element is provided by a central brick wall penetrating the entire mass from east to west, marking the new reception with its drive-in gate leading to the upper court and the accommodation buildings.
The solid parts of the southern and western facades are mainly clad in wood, while the northern facades are rendered.
