Traditional Concrete House - Concrete Houses - 11 Abodes That Are Solid as a Rock - Bob Vila
Warm in Winter
With a nod to traditional, gabled rooflines, this concrete home in Minnesota is anything but old-fashioned. The walls were poured in two wythes (vertical sections) with rigid insulation placed in between. The thermal mass of the well-insulated concrete walls, together with south-facing glass walls and skylights, keep this modern house warm during the brutally cold Minnesota winters.
