Cartography of the apartment
This article maps the physical space of the apartment in Chapter One. For the building's structure, see Bolton Street car park.
The apartment occupies the top storey of a residential tower above Bolton Street car park. It is accessed in Chapter One when Katita wheels the unconscious Leif across two parallel wires stretched from the car-park roof — an act of "surgical precision" — and surprises the elderly residents, Mr & Mrs McRae.
The McRaes are equipped with pendant exoskeletons of "silvered metal" and respond to the invasion with a "cartoon battle" that becomes one of the novel's key comedic and mechanical interludes. The apartment itself is sparsely described in the prose — the narrator's attention fixes on the exoskeletons, the residents' surprising politeness, and the fact of Leif's continued unconsciousness.
The space functions architecturally as a threshold: entry from the exposed rooftop; exit down a 12-storey spiral stairwell that leads to a street-level eatery. It is neither fully interior nor exterior, neither fully domestic nor public. Katita pauses there and rakes dust on the apartment floor in patterns resembling a zen garden, "brooding on history and the truth of things" — a moment of stillness inside machinery.
Some adaptations (manga volumes, anime episodes) expand the apartment into a full sequence: mapping its rooms, its exoskeleton charging systems, Mrs McRae's biography. The operatic works often stage the exoskeleton duel as a choreographed mechanical ballet. The apartment remains suspended — architecturally, narratively — at a height that permits neither ascent nor safe descent.
