Fourth in an occasional series, and this found in one of the true icons of 20th century architecture, designed and built between 1927 and 1929 by Konstantin Melnikov.
One of the many quirky delights of the Melnikov House in Moscow is this internal intercom system. Two holes on the ground floor corridor. The right speaks to a tube on the top floor, the left to the entry on the street, in a prototypical door-entry system. (The left isn’t working, apparently, but will do again one day.) These holes simply snake up through the walls to the studio, and down under the ground, out to the street. They are simply metal tubes, carrying the voice.
It’s like the old idea of two tin cans joined by string, yet replacing the string with a tin can extruded to become the entire length of the system.
At the top of the house, the other end. A large metal tube rises up out of the floor in the corner of the studio, with a ‘speaker’ on it.
On the mezzanine above, another hole to speak/listen into.
It’s as simple as could be, and its affordances are entirely clear. Speak into the hole. Listen to the hole.
It is very low power. In fact, no power. And certainly resilient, save a small rodent crawling into a pipe and staying there. It is seamful—perhaps not particularly beautiful seams, but seamful nonetheless—and thus entirely in keeping with Constructivist/Functionalist principles.
In an age of contingent smart home systems, and IoT-enabled domestic infrastructures, I admire the way these snaking tubes simply reach for humble physics, the resilience of their dependence on sound waves and hard surfaces, subtle enhancements to living baked into the building. Learning from 1927.
