Exhibition scenography and design: Holzer Kobler Architekturen. The exhibition will be opened on 11 July and will run until 31 December 2020.

Based on a exhibition tour in 6 chapters, the visitors in the 2,500 m² exhibition hall are taken on a journey through five centuries of Saxon industry-culture history. By way of over 500 unique exhibits, a broad cultural and historical panorama unfolds: From the legendary beginnings of mining in the Renaissance period and the already early on internationally connected textile industries of the 18th and 19th centuries, through the phase of high industrialisation, the catastrophes of the First and Second World War, right up to the time of the GDR, the exhibition – curated by the Deutsches Hygiene-Museum Dresden under the direction of Thomas Spring –, gives us a look at the present time and also opens up perspectives of the future of the Free State of Saxony.

On August 11, 2020, "FUNNY MONEY. Money in Caricatures" opens at the Oesterreichische Nationalbank in Vienna. The new temporary topical exhibition presents itself in a "fragmented" showcase structure offering a wide variety of caricatures with insights into the subject areas: money – currency – economy. Exhibition: In cooperation with WGA ZT GmbH. Graphic Design: 2xGoldstein.

From Charlemagne to Frederick Barbarossa: in five sections the exhibition explores the different conceptions and strategies of their rule of a selection of imperial personalities in their domains in the Rhine region over five centuries. The exhibition levels are structured by way of floor-to-ceiling walls, thereby creating their own spatial composition of the rooms and a new rhythm for this tour through the Landesmuseum Mainz (DE).

The strong colors of the scenography create a unique atmosphere for each section, in order to symbolize the character and creativity of the individual potentate, at the same time providing attractive surfaces for the presentation of the precious objects. As an additional means of communication, informative graphic elements and illustrated short films lead the visitors through life and world events in the Middle Ages. A background soundtrack produces a mystical atmosphere, thereby shaping the exhibition experience of the visitors in a very subtle way.

The exhibition in the Landesmuseum Mainz (D) is open from September 9, 2020 to April 18, 2021.

"In Jail. On deprivation of freedom" deals with life behind bars – with confinement, detention conditions, exclusion, but also reintegration and the role of the judiciary. A manifold scenography explores the inside and outside of prisons in a colorful and positivistic manner. Historical, philosophical, anthropological and sociological aspects of incarceration reveal the ambiguous reality of detention, they break down stereotypes and raise the possibility of alternatives to authoritarian and antiquated punitive systems.

The exhibition was realised in a trinational cooperation of the International Red Cross and Red Crescent Museum in Geneva (MICR), the Musée des Confluences in Lyon (MDC) and the German Hygiene Museum in Dresden (DHMD). The curators of the three museums, Isabel Dzierson, Marianne Rigaud-Roy and Sandra Sunier, have jointly developed the concept, the design was created by Holzer Kobler Architekturen. After its presentation in Geneva (February 5 – August 18, 2019), the exhibition was shown at the Musée des Confluences in Lyon from October 18, 2019 to July 26, 2020. It will open at the German Hygiene Museum in Dresden on September 26, 2020 and can be seen until May 31, 2021.

With the exhibition "Difficult Heritage. The Linden-Museum and Württemberg in Colonialism" the Linden-Museum takes a look at its own history with regard to colonialism and post-colonial issues. Conceived as a summary exhibition of works, it focuses on the process of coming to terms with history through a conscious shifting of perspectives. This basic concept is taken up by the exhibition design. Numerous modules with different creative approaches to the topic are distributed around stands and open fragmentary exhibitions in the rooms of the museum. Empty spaces and breaks in the scenography demonstrate the complexity of dealing with this cultural heritage. At each station, participation is encouraged as well as opportunities for in-depth research and discussion.

In the context of social (cultural) spaces, where are the essential challenges of an increasingly diverse society? Additionally where is the design and clear allocation of spaces and architecture as well as their simultaneous mechanisms of exclusion of different social groups or a rapid development of digital innovation?

As part of Women in Architecture Berlin, Barbara Holzer invites three personalities from the fields of architecture, science, media and art who with their different wealth of experience will explore new connections to architecture and (open) space in a lively debate.

Holzer Kobler Architekturen is responsible for the entire structural corporate design of the Humboldt Forum, for the exhibition scenography of the ivory exhibition "Terrible Beauty: Elephant – Human – Ivory" and for the design of the Humboldt Academy. 

In the foyer of the Humboldt Forum, the Kosmograf welcomes visitors with an eye catching display of art and information. Standing over 20m high, it is an aesthetic sculpture which embodies the aspiration and mission of the Humboldt Forum. The Kosmograf is a collaboration between Holzer Kobler Architekturen as designers of the sculpture and cutting-edge artist Ali Hossaini, who developed the brand and artistic concept.

Ivory – precious substance for cult, art and everyday objects, sign of luxury, status, greed and power, testimony of colonialism, exploitation and human cruelty. The multi-layered ways of looking at ivory characterise the design of the exhibition in a motivically intervowen course. The ivory exhibition runs from 20 Juli 2021 to 28 November 2021.

The Humboldt Academy in Berlin's Humboldt Forum is head office and starting point for organised guided tours for visitors and for group events as well as venue for all kinds of educational, social and cultural outreach, from workshops to talks, panel discussions, drop-ins or further projects. It thus spans 1000 square metres of space on two levels, designed to meet varying needs and requirements. In addition to service and office units for education and public programs, the available area encompasses eight generously equipped work and seminar rooms of superior quality, an activity space as well as work and play areas for up to 200 users.

For a functional and diversified room concept, a furnishing system based on modules was developed that can be adapted with great flexibility. The diversified equipment, furnishing and colour coordination give the different functional areas a very individual character. Colours, materials and lighting create specific, identity-forming accents. Sliding panels made of glass and acoustically effective curtains contribute to a communicative yet concentrated atmosphere.

The Humboldt Academy celebrates with a family festival on 21 August 2021.

As part of this year’s first online scenography colloquium at DASA Dortmund (1-2 September 2021) under the motto "Same, same but different", Tristan Kobler reflects on the planning and creation of the exhibition on health care "Heilen und Pflegen" (Healing and Caring), which was realised during the Corona pandemic, and spans an arc from the diverse imponderabilia to the creative approaches to solutions of contemporary exhibition scenography.

In the first single exhibition focussing exclusively on the Premonstratensians, outstanding works of art dating from the Middle Ages to our era show the cultural, spiritual and economic work of the order from its origins until today. The exhibition scenography is based on the concept of: reuse – reduce – redefine. As far as possible, display cases were taken from existing stocks and integrated into an overriding design corresponding with the architecture while remaining delicate and minimalistic. An atmosphere of differing identities is achieved in the individual exhibition rooms by means of a colour concept based on the colours of the pictures and objects of the exhibition.

The timeline in the choreography of the exhibition is conceived like a loop. On the stairs leading to the exhibition areas, visitors are welcomed by media projections showing the Premonstratensian Order as it is today. With knowledge of the present time, one can go back to the beginnings, and from there move chronologically on through the centuries.

The exhibition will be open from 8 September 2021 to 9 January 2022.

As part of the interdisciplinary MA1 Architecture and Interior Design, the PBSA's "Curated Studies" team is organising – as a prelude to the winter term – a lecture event on issues of participatory, contemporary neighbourhood development and on the "Köln-Kreuzfeld - Stadt-Land+Feld" project.

A new district is to be built in Cologne. As part of an urban development competition with intensive involvement of the local population, the city of Cologne is planning a new district on a "greenfield" site. This district will extend the districts of Chorweiler and Blumenberg, which are „socially challenging“ in parts, in a north-westerly direction. The BRAIN FOOD event will take place online via Zoom on 29.09.2021 from 9:30 to 18:00.

From 12 March to 9 April 2022, the annual exhibition of the Berlin Chamber of Architects will present selected projects at Living Berlin as a contribution to the reconstruction of our society in terms of building culture.

The new Raumforum Aargau aims to stimulate the discourse on architecture, planning of settlement and landscape and transport  to bring it into line with today’s social challenges. Presented to a wider public beyond the professional and administrative circles, Barbara Holzer will take part in a first event “In Search of Community-Building Spaces” on March 16, 2022 at the Tivoli Shoppi in Spreitenbach, which explores the questions of new usage concepts and contemporary transformations of shopping worlds in the 21st century.

Fr, 06. Mai 2022, 12:30-13:30h Podiumsdiskussion

Bauen Frauen anders als Männer? Wählen sie andere Materialien aus? Wie wählen Sie Materialien aus? Wie funktioniert die Kommunikation mit der Bauherrschaft? Wie jene mit den Handwerkern?

Gibt es eine spezifisch weibliche Architektur?

Solche und ähnliche Fragen werden an der Podiumsdiskussion im Swissbau Fokus in einer hochkarätigen Frauenrunde diskutiert. Dabei geht es nicht darum, auf Konfrontation mit der noch immer von Männern dominierten Bau- und Architekturbranche zu gehen, sondern aufzuzeigen, welche neuen Perspektiven Frauen im Beruf als Architektin und Innenarchitektin mitbringen. Herangehensweisen, die neue Impulse geben können. Es soll keine frauenrechts-politsche Veranstaltung werden, sondern aus dem Leben und Schaffen von Innenarchitektinnen und Architektinnen erzählen, die bereits Gutes erschaffen haben und noch Grossartiges erschaffen werden.

Im Anschluss an die Veranstaltung findet ein Networking-Apéro statt.

The Kunstmuseum Bern accepted the legacy uf Cornelius Gurlitt (1932 - 2014) in November 2014. Since December 2021, around 1600 works of art from the estate of the art dealer Hildebrand Gurlitt (1895 - 1965) have also physically arrived at the museum. Beacuse Hildebrand Gurlitt traded in art during the National Socialist era in Germany (1933 - 1945), the inventory has been scrutinised for possible cases of Nazi looted art since 2013.

The exhibition offers in-depth insights into the Gurlitt legacy and the scolarly research of it. Individual thematic rooms explore, in detail, the ethical guidelines, legal framework and results of this unique international provenance research project. We show how the Kunstmuseum Bern responsibly fulfils its obligations in dealing with works of art in its acceptance of the Gurlitt bequest.

Barbara Holzer ist taking part of the jury board regarding a new tower komplex project in Hegi, Winterthur.
