Do we still need new buildings?


Jasna Moritz (kadawittfeldarchitektur)

In this episode, host Martin Pauli talks to Jasna Moritz from kadawittfeldarchitektur about the future of building. They discuss why sustainable architecture is more than just reducing CO₂ emissions and why a holistic approach is necessary. Particular focus: circular building. Instead of constantly building new buildings, we need a more conscious approach to existing buildings, materials and resources. How can we design buildings so that they are flexible, demountable and reusable? What role do social and functional aspects play in this? And why are honesty and a dialogue-based planning process essential for sustainable solutions? A multi-layered discussion about the challenges and opportunities of the building revolution.

Key learnings

The transformation of building requires a holistic approach

Architecture must understand sustainability not as an isolated metric, but as a multi-layered process of consideration. It is about thinking beyond CO₂ equivalents and carrying out a holistic assessment: What resources are really needed? How can buildings be designed intelligently and sustainably? In addition to the environmental impact, the social context, space efficiency and quality of use also play a decisive role.

Honesty and working in dialogue are key skills

Modern architecture requires the courage to admit uncertainties and to develop solutions together with all those involved. Not perfect answers are required, but an open, transparent process. The ability to moderate complexity, find compromises and realise step-by-step improvements is becoming more important than the demand for immediate perfection.

Dealing with existing buildings is becoming a key challenge

The future of construction does not lie in new builds, but in the creative transformation of existing buildings. The aim is to recognise potential, rethink spaces and develop flexible usage concepts. Instead of rigid room programmes, improvising, context-aware solutions are required - with the aim of meeting actual needs and using resources sensibly.
