013_S82_a modern tree top house
A new self contained flat was meant to be designed in the roof space of an 1905 "Gründerzeit" villa in Berlin. The spacious maisonette living with at least 4-5 rooms had to be integrate into the roof while preserving the street view and its historic appearance. More information can be found here...
The idea that defines this lofts is upside down. Instead of having the functions such as bathing, storing, cooking and working centrally arranged, open living spaces are placed in the middle. The living room extends over the center to all four outer sides and this creates exciting spatial connections. Through niches and generous dormers at the end of each "arm", some intersting views arise.
The site on Herdenstraße in Zurich is characterized by a large private and community garden area. This green area will be extended onto the site, however, the extended ground will be levelled up to a small “green hills” allowing galleries and retail to ‘hide’ below. More Information here...
The new TAZ building is taking on the egalitarian and non-hierarchical mindset of the renown left-oriented editing and publishing house, and reinterprets this approach spatially anew. Consequently, rather than using isolated floor plates, all employees are seated on “one level”.
059_DNA of learning
At the center of the competition site, the new education center will create a new focal point at the northern end of Europaallee. The new building is arranged in such a way that the existing development along the Europaallee is complemented by the urban planning. More information can be found here...
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, Hannah Reckenthäler, Deborah Matter
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.
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.
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.
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.
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”.
