Apartment Building ACME, Sofia, Bulgaria

Roofs and Facades Merge

Located on the foothills of Vitosha Mountain in Sofia, ACME is a residential complex consisting of three building volumes accommodating eleven apartments. Using the natural slope of the terrain, the archi­tects have stepped the residential buildings down the slope. The architectural concept focuses on the design of the roofs, which merge seamlessly with the façades and are treated like a fifth facade.

While the upper two stories and roof are clad in Swisspearl panels, the lower two floors are clad in sienna-colored masonry. The smooth, dark Swisspearl panels create a strong visual contrast with the russet textured brick façades. Generous planes of glazing break up the facade planes, afford views, and flood the interior of the apartments with natu­ral light. The third-story windows merge into inclined roof skylights, thus emphasizing the continuation of the up­per floor with the roof. By recessing the facades on the end facades, in­timate covered loggias have been created. Each apartment has a loggia that overlooks the sur­rounding garden landscape or Vitosha Moun­tain rising behind.

By seamlessly continuing the Swisspearl facade cladding as a roof covering, and eschew­ing an eaves overhang, the archetypal form of “house” has been abstracted and the scale of the houses visually reduced. The wider building has a lower pitch than the two narrower building volumes. Although the buildings differ, they clearly form an ensemble due to the consistent and independent materialization.

A strong & high-performing roof

The reinforced concrete roof structure was protected first with a waterproof, thermal insulating layer and above covered with high-performance Swisspearl fiber cement panels installed on aluminum profiles. Some of the positive attributes of Swisspearl panels include their high level of fire resistance, their frost resistance, and the ability for them to be recy­cled.

The height of the building is visually reduced by running the roofing material over the eaves’ edge as façade clad­ding. The smooth, dark Swisspearl panels create a strong visual contrast to the brick façade of the lower two floors.
