Vienna's developer competitions
Public developer competitions are a quality assurance tool used to ensure provision of affordable housing of a high standard and innovative project content. Commercial and non-profit developers and architects form project teams competing with one another to develop designs for implementation. The winning projects are determined by an interdisciplinary expert jury, based on assessment criteria such as architecture, ecology and economy.
The awarding of subsidies with residential housing construction in Vienna was reorganised in the 1990s. The aim was to reduce construction cost, while at the same time attaching importance to raising residential housing standards in ecological and social terms. Residential housing projects applying for public funding are subject to thorough checks under a comprehensive and standardised evaluation system.
Submissions for residential housing projects are scrutinised to determine whether they meet the basic requirements making them eligible for funding. A particular element in this context are open developer competitions. There are both one-time grants and grants in the form of a loan to be repaid within 25 years. The grants are awarded by square metre of usable residential floor space.
The developer competition for subsidised residential housing projects from approx. 200 to 300 housing units upwards is a public invitation to tender and serves to single out those prospective real estate purchasers who submit the best designs for development concepts.
The public competition comprising one or several stages, including the search for interested parties in the run up, is launched through a public call for tenders.
Following a preliminary check by an external consulting engineer, the submissions are judged by an expert jury on four main criteria: architecture (= urban structure, residential structure, appearance, innovation potential), economy (= site cost, construction cost, costs and contractual terms for occupiers, cost relevance of building equipment), ecology (= building engineering, building ecology/low-impact building, residential ecology/construction biology, free space/green space/urban ecology) and social sustainability (= suitability for day-to-day living, cost reduction through planning, living in communities, housing for changing needs), in which the focus is on overall quality and especially a balance between the four main criteria.
The jury's report informs participants of any recommendations or requirements.
The developer competition is a transparent procurement procedure for Vienna Housing Fund sites and supports quality assurance in the area of subsidised new residential building and quality control prior to the granting of subsidies for residential construction.
