Who we are

rundzwei is a modern architectural office by the two founders Andreas Reeg and Marc Dufour-Feronce. rundzwei considers Research and Design as two central parameters for a sound sustainable and modern architectural understanding, which combines space, materiality, resources, local history and natural environment with a sophisticated design.

 

Before founding rundzwei Marc Dufour-Feronce and Andreas Reeg held leading positions working for international renown offices such as Herzog & de Meuron, LAB architecture studio and ACME in, Switzerland, the UK and the UAE. The project experience ranges from masterplans, housing towers, museums and exhibition spaces, shopping centres to residential units.

 

rundzwei consist of a team of architects and Engineers in freelance and full-time employment, which sketch, design, research, plan and control. Together we accomplish architecture with character and high quality.

 

Alexandru Isan, Enrique Mesia, Italo Celiento, Irene Modica, Kejwan Gross, Miriam Wierzchoslawska, Roberta D'Alessandro, Sophie Dufour-Feronce, Agata Klein, Christine Huber, Gesa Falkenburg, Jakub Spaniel, Luca Di Carlo, Anastasiya Kozina, Miriam Lopez, Matthias Rühl, Johann Göhler, Ana Domenti, Andrian Fernandez, Raimon Espasa Bou, Lou Pelosoff, Paulin Sensmeier, Michelle Bähr, Sunghoon Go, Marie Nägele, Asya Güney, Constantin Blömer, Hannah Clemens, Johann von Weiss, Isabel Karge, Shadi Zaghloul, Hanna Reckenthäler, Deborah Matter, Sophia Hölscher, Paolo Bradicic, Pavlo Zabotin, Marielena Hickmann, Magdalena Baraniak, Mareike Beumer, Katarzyna Cichecka, Lillie Ritter, Karim Omar. 

What we believe in

rundzwei believes that contemporary architecture depends on the development of coherent design concepts which work not only on paper, but even more so in reality. Our design concepts are the product of a thought-through research process which integrates space, materials, local history and contexts. While we aim to contextualise architecture we challenge the existing, reinterpret modernity and explore the unexpected. rundzwei filters and focuses the relevant potentials and qualities of each project to create innovative and unconventional solutions in a new contemporary form. This leads to unexpected concepts that often go beyond the scope of the actual brief and positively affect and enhance the final goal of each project and client.

We believe that sustainable architecture starts with the concept and should not exclusively rely on costly ex-post technical solutions. Therefore rundzwei integrates architectural solutions to reduce energy consumption and heat gain into the design concept of the built environment before enhancing them through technology.

What we offer

rundzwei works on a broad range of projects from all fields of contemporary architecture, urban planning, interior and product design. Through our conceptual and research based design approach we have become the perfect partner for densification on complex sites in urban areas. We are working with private, corporate and public clients and offer the full spectrum of design services. The conceptual design strength of rundzwei is rounded up through an extensive network of partnering offices and consultant firms which enable us to offer the full spectrum of architectural services from feasibility studies, concept design, energy consultancy through to construction management, documentation, sales brochures and websites. By collaborating with foreign architectural and engineering offices we ensure that the high quality of our concept and design for international projects is realised up to the built project and beyond. This way every client’s individual needs can be satisfied through our trusted network.

 

Schematic Design

We offer researched based concept driven architecture and work in close exchange with our clients. Together with the client we form the brief and the parameters of each individual project. Our designs are informed by local references, user group studies, sustainability, materiality as well as cost efficiency and local regulations.

 

Design Development

The first interpretations of the clients brief are deepened and the concept strength enhanced by further development and collaboration with the client and the authorities. We offer all design services up to the planing application. On international level we tend to team up with specialist partners from our broad network of collaborators depending on location and size of the project.


Construction Documents

We offer the full range of construction documents on a national level. For large scale projects and on international level we collaborate with specialist partners.


Tendering and Construction Supervision

For smaller projects we are the perfect partner to provide tender documents and specifications. We help the client with the tendering and contracting of construction firms and control the correct execution on site.

For larger projects this phase is covered by our partnering offices or by the clients choice of main or general contractor. rundzwei offers the architectural site supervision and oversees the tender process.


Joined Private Client Projects "Baugruppen"

rundzwei offers service for private client groups that enable the realisation of large scale housing and social projects. We help in the formation of the groups and their members, offer advice on site acquisition and make first feasibility studies. After formation of the group and the acquisition of a site rundzwei offers the full spectrum of architectural services to these “Baugruppen”.

Who we work with (employees and collaborators)

Together with LOOM for all topics around digital & media and Stoffers/Steinicke as full blood designer we share our 800m² creative Loft-Office, the Entrance B. This generates a perfect symbioses of design lovers and enables us to provided services to our clients beyond the architectural scope.
