The Corridor as a Street: How the 2025 Stirling Winner Designs Loneliness Out of Old Age

A prize that went to the opposite of a landmark

On 16 October 2025 the RIBA Stirling Prize, Britain's most closely watched architecture award, went not to a museum or a tower but to a block of subsidised flats for people over 65 on Southwark Bridge Road in south London. Appleby Blue, designed by Witherford Watson Mann Architects for United St Saviour's Charity, is an almshouse — the oldest form of social housing in England — rebuilt for the century of the loneliness epidemic. It is the practice's second Stirling, after Astley Castle in 2013, and it also took the 2025 Neave Brown Award for housing. The jury praised a building that treats growing old as a design problem worth solving with real generosity rather than the bare minimum.

The oldest housing type, re-read

Almshouses have sheltered England's poor and elderly for more than a thousand years; the model predates the welfare state and still runs, charity by charity, in courtyards and cottage rows across the country. Their enduring shape is a cluster of small homes gathered around a shared garden or court, historically with a chapel and a founder's crest. United St Saviour's traces its own endowment back to the Southwark parishes of the sixteenth century. What Witherford Watson Mann understood is that the typology's real invention was never the picturesque cottages — it was the plan: putting front doors around a common ground so that residents cross paths without arranging to. Appleby Blue keeps that logic and drops the nostalgia, stacking the courtyard model into a dense inner-city block of 57 flats over two to five storeys, in a blueish-brown brick with precast concrete and solid oak, topped by a stepped-back roof garden.

Circulation as the social engine

The building's central idea is almost boringly practical: make the corridors too good to hurry through. Instead of the mean internal passages that most flatted housing uses to reach front doors, Appleby Blue wraps its homes in wide, terracotta-paved open galleries lined with planters and benches — what the architects and jury alike call streets in the sky. They are deep enough to stop on, to leave a chair out, to grow something, to talk. A home's front door and kitchen face onto this shared street rather than a sealed hall, so the ordinary business of the day — putting out a plant, waiting for a kettle — becomes visible to neighbours. Loneliness in later life is rarely cured by a single scheduled event; it is held off by the accumulation of small, unplanned encounters. Appleby Blue engineers those encounters into the route everyone already takes to their own door.

A garden room and a woodland courtyard

At the heart of the block sits the piece that does the heavy social lifting: a double-height, fully glazed garden room with a community kitchen, its large sliding doors opening south onto the courtyard. This is not a token residents' lounge tucked off a lobby; it is a bright, generous room with communal dining tables and oversized armchairs, staffed and programmed, and open to the surrounding neighbourhood as well as to residents. The courtyard it looks onto was designed with landscape studio Grant Associates to read like a small woodland — mature trees, dense planting and a cascading water feature whose sound softens the city. A gentle glazed ramp, not a flight of steps, leads up into all of it, so that mobility never quietly decides who gets to take part.

Facing the street, not turning from it

Housing for the old often defends itself against the city with blank walls and a single controlled entrance. Appleby Blue does the reverse. At ground level, floor-to-ceiling bay windows push out toward Southwark Bridge Road, giving residents a front-row seat on the passing traffic, the bus stop and the ordinary drama of the pavement. The move is deliberate: watching the world go by is itself a form of belonging, and the glazing lets residents stay connected to the life of the high street without having to leave the safety of the building. The bays, the public garden room and the year-round programming together dissolve the usual hard line between an institution and its neighbourhood, so the building reads as part of Southwark rather than a compound set apart from it.

What the model actually proves

Appleby Blue matters beyond its 57 households because it is an argument, built at full size, about how to house an ageing population without warehousing it. Its budget was modest and its materials are plain and long-lived; the generosity is spent on space that is shared rather than on expensive finishes. Research on almshouse living has linked the strong sense of community they create to measurable gains — one recent study associated the model with several added years of life — and the mechanism is exactly what this building foregrounds: independence kept, but isolation designed out. In a year when the Stirling shortlist included far flashier work, the jury chose a quiet almshouse. The signal is hard to miss. The most urgent architecture right now may not be the tallest or the most photogenic, but the kind that decides, deliberately, where an eighty-year-old will run into a neighbour.
