Casa L4 is a concrete holiday home designed by Luciano Kruk Arquitectos’ titular architect and his girlfriend, Ekaterina Künzel.

Situated on the Costa Esmeralda, a stretch of coastline south of Buenos Aires, the sleek design fuses board-marked concrete with glass in what looks like a very contemporary take on Brutalism.
Fitted with a rooftop pool, the central living plan places the four bedrooms in the corners of the rectangular design. Clerestory glazing and narrow strip skylights allows natural light to filter between the bedrooms and living room while keeping them divided.
This division continues throughout the rest of the structure, where a cast concrete staircase slices it in two, with the kitchen and dining room on one side and the living room on the other.

Casa L4 bears a striking resemblance to Luciano Kruk Arquitectos’ SV House.
