Beton-Balkone
Frankfurt am Main

Two super-sized balcony stuctures - comprising prefabricated concrete columns and platforms - complement the scale and massing of the late nineteenth century apartment block they abut.

The concrete’s etched finish - the result of extensive testing with several 1:1 samples, incorporating various aggregates and pigments - references the use of red sandstone in the door and window trims. And as an elegant counterpoint to the scheme’s over-all solidity, self-supporting stainless steel railings neatly enclose each floor plate.

The spindles in each railing section sit within precisely aligned, 50mm deep countersunk stainless steel bushings, collectively configured as a single unit within the pre-cast concrete mould in order to eliminate any movement. A series of circular steel plate surrounds completes the railing detail, slotting into the bushings and sitting flush with the floor.

Internally, the platforms are calibrated with a 2% fall to allow for drainage. 3cm thick sandstone slabs, positioned on footings, provide a safe and durable surface.

In essence, the project’s composition and geometry represents a seamless integration of making and thought, culminating in two contextually measured structures.
