City of the future. Rennweg Vienna study
Urban Renaissance
What will the cities of the future look like? How do we design them so that they remain sustainable, liveable and socially mixed? In conversation with Sergei Abramov, a journalist from Lider media, Dominik Philipp formulates clear perspectives on a new urban self-image – between digital tools, timber construction, the circular economy and social responsibility.
What does it mean to think urban today? Tomorrow's cities will be socially mixed, ecologically resilient and architecturally adaptable. It's about more than functionality - it's about quality of life and sustainability.
8 takeaways from the discussion

Village im Dritten – a new urban quarter in Vienna with around 2,000 apartments, 39,000 m² of office and commercial space as well as a school and two kindergartens. The heart of the quarter is a park covering around two hectares. Visualisation: © Squarebytes
1. Rethinking the city
Our cities are facing profound changes. Urban space is being reinterpreted – as a changeable structure that responds to human needs, ecological principles and technological developments in equal measure. It is no longer just about function, but about quality of life. The city of the future is not a rigid structure, but a flexible system: adaptable, inclusive, resource-conserving.

The Kleineschholz quarter integrates a wide variety of housing and building types, with a focus on affordable housing. Families and singles, young and old, locals and newcomers live here. Craftsmen, the self-employed and service providers work here. Together they form a stable social structure with different responsibilities, life cycles and local connections.
2. Spaces of the future: lively and recyclable
Architecture should be the backbone of vibrant neighborhoods that combine living, working and leisure. Buildings are conceived as material banks, public spaces as meeting places. Timber construction, modular systems, digital twins and dismantling indices characterize a new aesthetic of smart building.
3. Material mix with attitude
Hybrid constructions made of wood and concrete combine ecological advantages with technical performance. Modular construction facilitates dismantling and reuse. Digital planning methods such as BIM make sustainability measurable and traceable – from the idea to use.
4. Smart cities: digital, efficient and accessible
Smart cities rely on intelligent infrastructures, efficient resources and social integration. Sensor technology and data analysis help to optimize energy consumption and maintain buildings with foresight. At the same time, the spaces remain open for appropriation and diversity. The city thinks for itself – but it remains human.
5. Reversible structures instead of rigid systems
Sustainable architecture must be allowed to change. That is why DTFLR designs buildings with modular logic that can be adapted or dismantled over decades. A digital building library catalogs components for later reuse – in the spirit of an urban circular economy.

6. Urban space as a common good
Public spaces are more than just gap fillers – they create identity, enable participation and promote community. Projects such as KuKu23 in Vienna show how cultural and social uses can flourish in permeable, networked structures. Urban planning becomes a social process that takes local needs seriously.
7. Shaping integration
Architecture can strengthen social cohesion. Mixed neighbourhoods, diverse housing models and well-designed open spaces counteract segregation. Vienna shows how social housing can contribute to inclusion – both architecturally and politically.
8. Living spaces with prospects
A city worth living in needs quality craftsmanship, durable materials and scope for design. It favours mixing rather than separation, exchange rather than isolation. Investors, local authorities and planners pull together – for urban spaces that will still be sustainable in 50 years' time.
