We built the house in a historically significant agricultural landscape in North Espoo. The simple form topped with a pitched roof integrates the building into the wider context. The western slope of the woodland site is divided into two areas of differing character; the back part with pines and the rocky ground, covered with moss, with dry peaty forest in the front. This division is retained because the front yard is filled with activity; it contains the main entrance, children’s playground, terrace and a workshop. On the opposite side of the main building, with a more fragile nature, is a solitary path leading to the sauna.
The spot for the building was partially excavated in the slope so that both floors have close contact to the nature. Also the part of the building situated in a generous space between rocks has a timber structure, thus the building has a unified wooden frame system with wood wool insulation. Freestanding gluelam columns, plywood and tension bars at the end give the frame the required stiffness. Horizontal slabs consist of LVL-mainframe that is structurally combined with plywood and a cast concrete layer.
The main building comprises three zones: living and working, and a glass-roofed conservatory linking the two. During the day the living area is used for in-home child- care, the conservatory acts as a shared dining space and as the meeting room of the office. The office can later be transformed into a separate apartment.
Ecology and sustainability: The fully wooden building envelope is made of local wooden materials like spruce and pine. The envelope is well insulated, structurally protected and makes use of hygroscopic feature of wooden products. The building is equipped with a ground heating system and a high level ventilation heat recovery system. Snow piling adjust the ground floor slab ventilation. Other sustainability key factors are presented on a separate diagram.
