In a city where housing has become increasingly unattainable, the Pillar Penthouse (simply called Precarious Penthouse) proposes a radical inversion: the smallest possible dwelling elevated to the status of a monument.

A minimal microhome is placed atop a single slender column rising from an existing plinth. Traditionally, such a base would carry figures of power or memory. Here, it supports the most basic architectural unit — a space just large enough for one person to sit, stand, and lie down. A home reduced to its absolute minimum.

The structure is assembled entirely from reclaimed materials. The plinth and column are constructed from terrazzo elements salvaged from a previous Antepavilion project, grounding the proposal in a literal continuity of reuse. Above, a minimal structural frame made of recycled steel, a circular beam and an I-section welded into a cross, forms the primary support. This cross sits on the column via a simple, exposed connection, recalling a beam shoe or saddle joint, deliberately legible and direct.

One arm of the steel cross extends downward to become a narrow stair, a welded sequence of reclaimed metal fragments that allows access to the elevated room. The act of climbing is both functional and symbolic: an ascent into a position usually reserved for monuments, temporarily occupied by the individual.

Opposite the stair, a tension cable anchors the structure back to the ground, fixed to a large stone. This simple counterforce stabilises the system, making visible the otherwise hidden forces of balance and support. The entire assembly reads as both fragile and precise — a structure held in equilibrium rather than dominance.

One of the beams becomes the staircase and supports the structure. This  staircasebeam is secured within a minimal foundation of reused bricks, anchoring the intervention lightly but firmly into the site. Every element is either reclaimed, reassembled, or repurposed, a construction logic that rejects excess and embraces immediacy.

The dwelling itself is a compact enclosure made from reclaimed timber. Inside, space is reduced to its limits: only one position allows full standing height. There is no surplus, no redundancy, only the essential dimensions of inhabitation. It is not designed for comfort, but for clarity.

By elevating this minimal home onto a pedestal, the project renders visible what is often hidden: the shrinking conditions of living in London. The private act of dwelling becomes public, exposed, and monumentalised.

The plinth no longer commemorates power. It supports survival. Located at a road junction within a shallow leftover urban void, the Pillar Penthouse occupies a space usually ignored. Lifted on a single column, the dwelling hovers above the ground, making it highly visible to passing cars and pedestrians. What was once a residual space becomes a moment of attention — a fleeting encounter with the realities of living in the city.

The Pillar Penthouse (simply called Precarious Penthouse) is not a solution to the housing crisis. It is a monument!
