Today our team of more than 90 people from 18 countries represents one of the most successful and innovative architecture practices in Austria. Our architecture is clear, reduced, and committed to quality. For us, dialogue at eye level is of utmost importance.


Franz&Sue&walk the talk.

»We stand by our words. Always. This is what makes us a reliable partner, ready to walk short or longer paths, and winding roads, too.«


»We pay great attention to quality. That’s why we invest just as much time, energy, and devotion at the end of a project as in the beginning. And any point in between.«

Franz&Sue&the free radical.

»We believe in relevance beyond fashion trends. That’s why our architecture is clear, radical, and sustainable. Made by people for people, not for prestige or short-lived vogues.«

Franz&Sue&breaking routines.

»Contradictions and differences are essential to our approach, for they reveal new perspectives and potentials and keep us self-critical.«

Franz&Sue&the No.

»We stick to our values and take our responsibility to everyone who encounters our architecture very seriously. Therefore, a No is just as important to us as a Yes.«

From Architects with Love

We, the five partners at Franz&Sue, first met during our studies in architecture at TU Wien. After graduation we founded two independent architecture practices in Vienna: one as Franz, the other as Sue. In our legendary Fight Club discussion rounds we realised that not only do we share the same approach to architecture, but we also speak the same language when it comes to our business culture and our commitment to building culture. Then, in May 2017, we merged to form Franz&Sue.

Our city quarter house and architecture cluster Stadtelefant is a project that’s close to our hearts: an office building right beside Vienna Main Station in the new Sonnwendviertel neighbourhood, which we designed, developed, financed, and built together with affiliated architecture offices, institutions, and companies in the sector. We have been working here since the end of 2018.

Mimi im Stadtelefant cooks fresh food for us every day. We eat lunch together in our in-house cafeteria and network with other architectural enthusiasts at events.

  Franz&Sue&learning from one another.

»We are general planners who work in big interdisciplinary teams. We have learned to listen carefully and give the best idea priority over hierarchical structures. We’re convinced that architecture can truly succeed when there is a common vision and everyone puts their vanity aside now and then.«

  Franz&Sue&letting go.

»We believe that good architecture must be able to survive in the world on its own. This means withstanding changes and proving its adaptability, no matter how it is used. When we let go of our designs in the end, they must be able exist without us. Only then have we done everything right and can celebrate what we have created.«

After the competition is before the competition

The majority of our projects evolve out of architectural competitions. In the past years we have won a total of 40 competitions in the realm of educational, residential, and office buildings. At the moment 25 projects are in progress, including 12 educational facilities, 8 residential projects, and 5 public buildings.

In 2020 Franz&Sue were awarded the Lower Austrian Culture Prize in the category Architecture. Our projects were previously honoured with the Clients Award, the Austrian State Prize for Architecture, and the Fiabci World Prix d’Excellence.
