1st price urban development Bahnhof Süd Bassersdorf

Together with Lisa Euler, Westpol Landscape Architects and Kontextplan, we have won the competition for the urban development Bahnhof Süd in Bassersdorf – we are delighted!

From a multi-layered landscape to a permeable settlement: the new district is structured by a distinctive network of open spaces. With the “Riet landscape belt”, a generous open space with natural and recreational functions runs through the area from south-east to west. On its way through the neighbourhood, the belt becomes a gateway to the landscape, a neighbourhood veranda, a central belt of open space between more urban residential buildings and, finally, the edge of the settlement, which acts as an open structure between the new suburban neighbourhood and the surrounding area.

Guest Crit Chair of Architectural Behaviorology ETH Zürich

On 12 November and 17 December, we will be guests of Prof. Momoyo Kaijima at the Chair of Architectural Behaviorology at ETH Zurich.

“The house is the foundation of our living environment. Housing is not only a fundamental field of architecture but also a reflection of broader social, cultural and environmental dynamics. Focusing on Basel, we will approach housing by uncovering the relationships between buildings and their users, environments, materials and typologies.”

1st Prize Sportshall Seefeld

We are excited to share that we received the first prize in the open competition for adding two sportshalls, childcare facilities, a cafeteria and an assembly hall to a historic school building in Zurich Seefeld.

Except technical spaces, the entire program is organized above ground, minimizing underground volume and carbon emissions.

Looking forward to realizing this project together with landscape architects August + Margrith Künzel for the client from the City of Zurich.

Discussing ‘Bad Language’

EPFL Department Lecture

We are delighted to be invited to the lecture series of the Faculty of Architecture at EPFL in Lausanne this semester. On Tuesday 18th November, we will talk about the Primary School Guggach and the topic of “Community”.

“Community is an ambivalent concept. It involves both gathering through shared customs and exclusion. Some claim that inclusive communities do not exist. Recent history shows people more often unite through exclusion than inclusion. However, communities are not sealed. Philosopher Roberto Esposito explains that community ‘is not a property or territory to defend but a void, a debt, and a gift to others, reminding us of our otherness.”

Espenhof construction site

The construction site of the Elderly Housing Espenhof West is progressing. We are happy to present new photos by Sven Högger, that document the building process.

"Care Hubs" - Guest Critic at ETH Zurich

On November 12, 2024, Christian Weyell will be a guest at the Studio “Care Hubs” of Guest Professors Chie Konno, Wataru Doi and Yukari Iwata at ETH Zurich.

“This studio will focus on environments of care that need to be reconsidered, and aims to design new local community centers – Care Hubs –, where people can support each other independent of institutionalized frameworks. This studio will take place in Otelfingen, a rural village near Zurich with a population of about 3,000 people. While rapid population growth in urban areas weakens community ties, in peri-urban areas such as Otelfingen, a subtle network of people‘s lives and activities can be seen. In these areas, we want to find actors who can support and create the environment of care and think about the future of the community.”

Guest Crit HSLU

Kai Zipse is an expert / critic in the studio of Stefan Wülser at the Hochschule Luzern, for the mid-term review on 25th April 2024 and final review on 26th June 2024.

1st Prize Open Space Rosental Mitte

Our team of Studio Céline Baumann + Weyell Zipse, in collaboration with Knopp + Kniel and the ecologist Martin Frei, has won the competition Open Space Rosental Mitte.

The oldest still operating area of Basel’s chemical industry between Messe and Badischer Bahnhof will be transformed into an integral attractive and mixed district over the next decades.

We are looking forward to implementing our strategy for the design of the streets, squares and green spaces, in order to define a “set of rules for the open space”.
Activating measures and participatory processes complement the successive change of this central, yet for a long time publically inaccessible part of the city, to create social and urban qualities within a robust and resilient ecological framework.

Federation of Swiss Architects

Christian Weyell and Kai Zipse were appointed members of the Federation of Swiss Architects.

We are very honored and looking forward to being more actively engaged in shaping Swiss building culture.

INSIDE OUT – Raum für Möglichkeiten

Climate change and the associated consequences for people and the environment require us to question our building practice. Dealing with existing buildings is the key to sustainable construction. But how can we make buildings fit for future climatic and social changes – beyond mere refurbishment?

This semester, we want to explore the potential of climatic buffer zones in an experimental, design-led and constructive way. Zones, that are not clearly defined as indoor or outdoor spaces and can change their nature, offering spaces for opportunities. We are looking for future-oriented architecture that questions existing conventions and deals with constructive issues as well as social and societal aspects.

Exhibition Tokyo

We are very excited to be a participant in the exhibition „Swiss Visions“, by JSAA in Tokyo, together with our dear colleagues and friends Truwant + Rodet +, Waldrap and By Jung, shown from March 29th – April 12th 2024 in Axis Gallery, Roppongi, Tokyo.

"On the Ground" - Guest Critic at ETH Zurich

On March 12, 2024, Christian Weyell will be a guest at “Studio Unicorn”, Lisa Euler and Tanja Reimer’s guest studio at ETH Zurich.

“On the Ground – Plinth of the City: Contemporary architecture is in a “crisis of the plinth”. Too little importance is attached to the design and programming of first floors as places of encounter. Urban porosity, differentiated threshold spaces, striking streetscapes and the urban climate call for a new architectural repertoire for the base of the city.”

"WohnJoker" - Guest Critic at Technical University Darmstadt

Christian Weyell will be a guest critic at the Department of Design and Housing Prof.’in i.V. on Wednesday, 14 June 2023. Dipl.-Ing. Audrey Shimomura at the TU Darmstadt.

“In the design “WohnJoker” we investigate the interaction of an “addition” of a new element in the experimental layout of an existing large housing complex of the 1970s. (…) The aim of the investigation is to design the future of the large housing complex out of its structure itself, i.e. to work not against but with the idea. The spaces and conceptual building typologies offer enough interpretative play and movement space to be reinvented and developed again and again.”

“Filling the Void: the death and life of the great European high street, explores the future of the high street through performance-led design. The studio look at the opportunity to test and re-imagine our town and city centres so that they can become places for everyone, whilst also questioning the role of the architect as someone who is both a designer and facilitator of events and conversations that can bring communities and stakeholders together to understand what a place can become.”

“An indoor swimming pool for Kleinbasel: The implementation of a new use in the form of an indoor swimming pool in an existing spatial structure should thus create places of liveability and a common identity for the Basel population. Concepts that create overlaps between different uses have proven to be viable. Thus, not only a swimming hall should be designed, but also a concept of use should be developed for the building as a whole with which it is associated.”

“Architektur bedarf einer stringenten Logik und kann dennoch Unschärfe zulassen. Flux Order will in der Vereinigung des scheinbar Gegensätzlichen das Ungewisse als Potential begreifen. „Architecture as Cave“ beschreibt Architektur, deren räumliches Potential die individuelle Aneignung erfordert. Dem gegenüber steht die „Architecture as Nest“, in der die räumliche Situation durch die Architektur konstruiert ist. Im Spannungsfeld dieser Dualität soll im Entwurf eine Struktur gefunden werden, die den Spielraum der Möglichkeiten zwischen definiert und aneignungsfähig auslotet und somit das Potential des Wandels zum Ausdruck bringt.”
