These triangular tiles by Brooklyn studio GRT Architects can be arranged to look like the fluted columns of ancient Greek and Roman buildings, or rotated to form abstract patterns.
Produced by Hungarian company Kaza Concrete, the Flutes and Reeds tiles are based on the surface treatments found in classical architecture.

GRT Architects transferred the simple decoration of vertical concave flutes and convex reeds, which draw the eye up a structure and help increase the impression of height, into a modular format for laying across flat surfaces.
"Fluting and reeding are among architecture's oldest surface embellishments," said the studio. "The Greeks, and most who followed, treated these motifs as linear elements applied to columns, pilasters and walls."
"Greek columns can be thought of as modules or tiles in a way," GRT Architects continued. "Their proportions have fixed rules, there are options for surface embellishments, base and top details."
"From that small set of instructions comes literally centuries of architecture ? from the most austere to playful acts of virtuosity. This seemed like a good starting point to design a suite of tiles."

The studio chose to make the cast-concrete tiles triangular, so that they neatly tessellate and form the desired pattern. This also results in a subtle grid overlay when they are installed in the "correct" way.
But the shape also enables individual tiles, rows or large secti...
