A sharp, clean aesthetic defines the Szelpal house by Felber Architects in Solothurn, Switzerland. Bunker-esque, the two levels are connected by a wide concrete staircase. Concrete the main material used throughout is warmed up with photographs, blinds, curtains and floor to ceiling custom made bookshelves. The owners have opted for a neutral colour palette to lend emphasis to the natural hillside surroundings. Whilst, furniture is also kept to a minimum favouring wide open spaces. Windows also line the entire length of the home to ensure a seamless connection between the interior and exterior.
