As Baby Boomers age, more and more families are adopting the financially advantageous and efficient multigenerational home. Finnish architect Tuomas Siitonen's recently completed House M-M is one such example, and it brings together three generations under one contemporary roof in Helsinki. Clad in timber to match its forested surroundings, House M-M accommodates both the clients, a couple with two children, as well as the children's great-grandmother.
M-M House was built at the bottom of a granite rock slope on land belonging to the client’s grandparents, who also live on the property in a 100-year-old blue wooden villa located upslope. To reinforce the connection between the two buildings, Siitonen wrapped the new house around an existing garden of apple trees and lilac trees that it shares with the older villa. M-M House’s kinked roof also dips down in the middle to avoid obstructing views.
The great-grandmother’s living quarters are located on the ground floor in a small and accessible apartment. The clients and their children live in the larger upper-level apartment, where big windows overlook the treetops to give the family a treehouse-like experience. To meet the client’s desires for “ecological sustainability,” Siitonen mostly wraps both the interior and exterior of the house in wood. An under-floor heating and cooling system also helps eliminate the need for stand-alone radiators and reduce energy costs.
