Cutting curves or slices into the facades of buildings doesn’t just make them more visually dynamic, it can create terraces, divert prevailing winds, concentrate sunlight and direct the eye to particular views. These seemingly random depressions and voids completely transform the shapes of each structure, often leading to an alien appearance.

Twin Moon Cut-Outs

Two buildings set side-by-side look like they were dented by a massive sphere, the concave cut-out creating two moon shapes recessed into the concrete facades. Architect Moon Hoon designed the mixed-use Two Moon buildings for a South Korean client who needed one building for himself and another for his brother. The structures were envisioned as twins, with one sitting ever-so-slightly closer to the street than the other.

Each ‘slice’ that you see in the main volume of the TEK building by BIG Architects is a functional step, with the entrance spiraling throughout the interior to create one big continuous outdoor staircase leading to a series of terrace-like spaces before finally exiting onto the roof. The building, which is full of exhibitions paces, conference rooms, shops, restaurants and galleries, consists of a system of stacked plate-like pieces that also create solar shading for the interior spaces.

This barn-shaped house looks like a massive black-frosted cake that’s had slices randomly taken from its perimeters, revealing its white interior. These concave cut-outs act as terraces, reflecting and maximizing natural light.

Singapore’s historic Kampong Glam district is set to get a pair of curving skyscrapers arranged in a half-circle, one containing apartments, the other offices and a hotel. The DUO towers by Buro Ole Scheeren feature a stepped design that creates large outdoor spaces at various levels, and are covered in a distinctive grid of hexagonal windows.

Calgary’s tallest building, The Bow by Foster + Partners is a 58-story wave-like structure with a concave side gathering sunlight and a convex side reducing the load of prevailing winds. Atriums within the concave side separate the glass facade from the offices within, offering meeting spaces, lounges and sky gardens.
