This Lisbon coworking space was assembled almost entirely from reclaimed theatre sets

When the Teatro Nacional de São Carlos cleared out four decades of scenery from a warehouse in Alcântara, most of it was destined for landfill. Instead, it became the raw material for Fábrica Sul, a coworking space two districts away, where painted backdrops now serve as room dividers and a baroque staircase from a 1987 opera production leads to the mezzanine.

The design practice Gabinete Sul approached the project as an inventory problem before a spatial one. Every salvaged element was catalogued, measured and structurally graded; the floor plan was then drawn around what existed, rather than the reverse. 'We designed with a shopping list we didn't write,' says lead architect Carla Fonseca.

The theatrical origins are legible everywhere but never kitsch. Flats painted as Tuscan landscapes are hung in banks and lit from behind to act as glowing acoustic baffles. Stage weights anchor the legs of communal tables. A revolve platform, once used for scene changes, is now a slowly rotating meeting room booked in fifteen-minute slots — the space's most requested feature.

‘We designed with a shopping list we didn't write.’

Beyond its charm, the project produced something transferable: a reuse protocol documenting how non-standard salvaged elements can be fire-rated, insured and certified for workplace use in the EU. Gabinete Sul has published it under an open licence.

The office fit-out industry generates staggering quantities of short-life waste. Fábrica Sul's argument is that the barrier to reuse is not aesthetics or cost, but paperwork — and paperwork can be shared.
