Curitiba is testing a new approach to urban regeneration: rather than relying exclusively on public works, the Brazilian city is offering financial incentives to encourage private owners and businesses to reinvest in existing buildings.

The programme, Curitiba de Volta ao Centro (Curitiba Back to the Centre), has attracted 47 redevelopment proposals spanning housing, hospitality, commercial activities, gastronomy and creative industries.

According to figures released by the municipality on 30 September, the proposals represent approximately US$53 million in potential investment, including requests for around US$15 million in public subsidies.

The applications are now undergoing technical assessment, with evaluations expected to conclude during October.

The programme responds to a familiar challenge facing historic city centres: buildings that remain structurally useful but have lost occupants, commercial activity or the financial conditions necessary for renovation.

Rather than addressing these properties exclusively through public acquisition or large redevelopment schemes, Curitiba is attempting to make smaller private interventions more financially attractive.

The central mechanism is a reimbursement programme covering up to 25% of eligible costs for whole-building retrofits and up to 50% for the renovation of ground-floor commercial spaces with direct access to the street.

Instead of treating vacant buildings as isolated properties awaiting redevelopment, Curitiba is using public incentives to encourage multiple owners to reinvest in the existing city.

Of the 47 proposals received, 27 involve substantial interventions in buildings, while another 20 focus on activating commercial premises, particularly at street level.

This distinction is important. Whole-building projects can introduce new housing, hospitality or mixed-use programmes, while smaller ground-floor interventions may contribute more immediately to pedestrian activity and the economic life of surrounding streets.

The municipality has identified housing, tourism, gastronomy and the creative economy as priorities, recognising that a functioning city centre depends on a mixture of uses rather than a single development sector.

The initiative also extends beyond direct subsidies.

Curitiba has introduced tax incentives and planning measures intended to encourage the restoration of historic properties, the adaptation of underused buildings and the introduction of new residential uses.

The wider programme includes approximately US$25 million in proposed tax incentives, alongside the initial funding allocated to construction subsidies.

Applications are evaluated according to criteria that include sustainability, social impact, housing provision and contributions to the surrounding urban environment.

The programme also establishes conditions intended to ensure that subsidised properties remain in their approved uses for a defined period, discouraging investments that generate only short-term benefits.

For architectural practices, the initiative is interesting because it creates opportunities through a different commissioning route.

Instead of announcing a single major public building, the municipality is attempting to stimulate a collection of privately commissioned projects across an existing urban district.

These could involve residential conversions, heritage restoration, building upgrades, commercial interiors and mixed-use redevelopment, often requiring architects to work closely with property owners, investors and local businesses.

The opportunity for architectural practices lies not in one major commission, but in the possibility of many smaller projects becoming viable through coordinated public support.

The model also changes the relationship between architecture and urban policy.

A building owner may recognise the potential of an underused property but be unable to justify the investment required to transform it. A partial public subsidy can change that calculation, allowing a project to progress while retaining private responsibility for its development and operation.

For municipalities, the challenge is to ensure that public funding produces wider benefits rather than simply increasing the value of individual properties.

Curitiba’s approach attempts to address this through eligibility requirements, evaluation criteria and an emphasis on active ground-floor uses.

Its effectiveness, however, remains to be demonstrated.

The 47 submissions are proposals, not approved developments, and the approximately US$15 million in requested subsidies exceeds the initial funding envelope of roughly US$5.6 million. Not every application can therefore be assumed to receive the amount requested.

The next important stage will be the selection of eligible projects and the extent to which those investments translate into completed renovations, occupied buildings and sustained street-level activity.

For other cities confronting vacant commercial premises and ageing building stock, Curitiba offers an approach worth following.

Rather than beginning with demolition or a large new masterplan, the city is using financial incentives to make existing buildings more attractive to reuse.

For architectural practices, it illustrates how changes in public policy can create a market for adaptive reuse before individual projects are formally commissioned.
