Hugo Breitner

As Vienna's finance councillor, Breitner helped make municipal housing possible through tax reform, including the earmarked housing tax introduced in 1923. His importance is financial rather than architectural: low-rent construction required a way to pay for land and buildings without placing the whole cost on tenants. The programme also depended on the city's wider fiscal arrangements. It offers a useful comparison with systems funded chiefly through household mortgages or developer incentives.
