Built on the location of the 100-year-old house, the new home was designed with two apartments: the lower storey is for 91-year-old grandmother, the 120 square-metre apartment upstairs is the home of the couple and their two children.

Most of the building is made of wood. The building has floor heating coupled to ground-source heat so stand-alone radiators are not necessary. The energy needed for cooling in the summer also comes from ground-source heat.

Inspiration from architect:

Because the roof of the new building dips in the middle, it does not affect the familiar view from the villa to the rising slope across the plot. The footprint of the new-build follows the shape of the slope and creates a bend making the garden more intimate and shielding it from the public roadway.
