“Late in the evening, the birds sit on the new trees, hold meetings and give concerts,” says Marc Pouzol from Atelier le balto, describing the scenery in the tree nursery in the Kulturforum piazetta. It is an atmosphere that until recently could not be clearly attributed to the location. The area in Berlin’s Mitte district between Landwehrkanal, Grosser Tiergarten and Potsdamer Platz is home to renowned museums and event venues. These include the New National Gallery, the Museum of Decorative Arts and the Picture Gallery, as well as the Berlin Philharmonic and St. Matthew’s Church. Despite these important institutions, the Kulturforum is considered a negative example of modernist urban development. Among other things, the fragmentation of the area by the road layout and the imposing but monofunctional buildings prevent a coherent spatial whole. An urban landscape, as once envisioned by the architect Hans Scharoun, is only partially perceptible.

Furthermore, large, sealed surfaces such as the Piazzetta are a cause for concern in the face of the climate crisis. The STEIN design without shade-giving trees or other urban climate-regulating vegetation is anything but contemporary. It is true that structural measures in the open space and the design for the Museum of the 20th Century will remedy this in the future. But it will be some time before that happens. Reason enough to initiate a project to green the area in the here and now.

Since July 2023, under the artistic direction of Nationalgalerie Director Klaus Biesenbach and atelier le balto, the artistic and horticultural installation Baumschule Kulturforum has been under construction. The project was realized with the help of the St. Matthäus Foundation and in cooperation with the Prussian Cultural Heritage Foundation and the Neue Nationalgalerie. The basic idea is to create green islands of young tree groves to enhance the stone open space. To this end, Atelier le balto installed mobile planters with 21 heat-resistant species. Under the canopy of bladder ash, string trees, gleditschia and others, new places to spend time are created. The small grove is complemented by wooden seating furniture. In this way, the once unattractive place can be experienced in a new way.

The Kulturforum tree nursery will start with around 80 trees and a pergola covering around 250 square meters in front of Café Estrade on the Piazzetta. The project will continue to grow over the summer. A total of 200 trees are to be installed in the coming weeks. Then not only on the Piazzetta, but also on the grassy traffic circle in front of St. Matthew’s Church and finally on Scharounplatz. The three tree islands will then remain on the Kulturforum until the end of 2024. The temporary redesign will be accompanied by a rich program of events. The Kulturforum tree nursery is not only intended to improve the quality of the space. Rather, the initiators want to encourage people to think about the transformation of urban spaces in times of climate change. “This temporary project is intended to mark the beginning of permanent greening and active site development,” says Andrea Zietzschmann, Director of the Berliner Philharmoniker Foundation.

Atelier le balto seems to be the right office for this task. The work of Véronique Fauceur and Marc Pouzol from le balto is characterized by the recognition, visualization and transformation of unnoticed urban spaces. Through temporary or permanent interventions, they have been able to transform places that have been neglected in the past into squares or gardens where people can gather and linger. It remains exciting to see how the Kulturforum tree nursery will be able to transform this important area in Berlin Mitte.

No greenery, but irrigation: a cloud of mist over Zurich’s Turbinenplatz cools the urban space – as an immediate measure. Read here how the square is to be cooled down in the medium term and how the “Alto Zürrus” pilot project works.

The Alliance for Affordable Housing, with around 50 participants, met for the 1st Alliance Summit on April 27, 2022.

“A new departure in building, housing and urban development policy” is the motto of the coalition agreement between the traffic light parties. The words are now to be followed by action. An affordable housing alliance with around 50 participants met for the first alliance summit on April 27, 2022.

In a fair society, everyone should be able to afford a home. However, this is far from being the case everywhere in Germany. One thing is certain: more affordable and climate-friendly housing is needed. The coalition government has set itself ambitious targets to achieve this: 400,000 new homes are to be built every year. Of these, 100,000 apartments are to be publicly subsidized.

This intention is set out in the coalition agreement. The “Alliance for Affordable Housing”, which is based at the new Federal Ministry of Housing, Urban Development and Building (BMWSB), was set up to implement the ambitious targets. Together with the alliance, the ministry states that it wants to “initiate a construction, investment and innovation offensive in Germany”.

The Alliance for Affordable Housing began its workon April 27, 2022. It consists of 35 permanent members, including representatives of the federal states, municipal umbrella organizations, housing and construction industry associations and civil society organizations. Specialist guests are also regularly invited to provide advice. Support from the Bundestag is provided by twelve permanent, advisory guests from the parliamentary groups of the governing coalition.

The kick-off meeting took place at the EUREF Campus in Berlin-Schöneberg. High-ranking representatives of all governing parties, the federal states of Baden-Württemberg, North Rhine-Westphalia, Hamburg and Hesse, municipal umbrella organizations, industry and business associations as well as civil society and churches took part.

Affordable Housing Alliance: kick-off event in April 2022

The first Alliance summit was convened by Federal Building Minister Klara Geywitz (SPD) and consisted of the minister and top representatives of the associations. Prior to this, there were Alliance working rounds with the various Alliance members. They worked out the goals and content, the working structures and the timetable for the alliance process.

There was also a lot of criticism. For example, the umbrella organization of the German housing industry described the government’s housing targets as “illusory”. According to GdW President Axel Gedaschko, material bottlenecks, exploding energy costs, supply chain problems, rising interest rates and the uncertainty surrounding new construction subsidies from 2023 are combining to prevent the construction of affordable housing.

Minister Geywitz told dpa ahead of the meeting: “It’s about getting through a big hole: we have a huge need for housing in Germany, especially affordable housing. […] We also need the support of the construction industry, which needs to significantly expand its capacities but is under pressure due to rising construction costs and material shortages.”

According to Geywitz, almost 800,000 apartments in Germany have currently been approved but not yet built. Obstacles to planning are one reason for the slow progress.

Densification as a strategy

A draft of the final declaration of the Alliance for Affordable Housing shows that new housing is to be created primarily in conurbations. In this context, densification of existing housing plays a much greater role than new buildings or new construction areas.Filling gaps between buildings, adding storeys to houses and converting commercial buildings into apartments offer opportunities to densify German cities in an efficient and climate-friendly way.

However, according to the German Construction Industry Association, the ambitious targets do not match reality. The war in Ukraine and the ongoing consequences of the coronavirus pandemic are causing material shortages, price increases and significantly higher energy prices. As a result, certain projects have to be prioritized.

There is also criticism from politicians: Jan-Marco Luczak, the CDU/CSU housing expert, criticized the lack of solutions proposed by the alliance and noted that valuable time could be lost through theoretical debates.

Caren Lay from the left-wing parliamentary group, on the other hand, criticized the fact that many expensive luxury and owner-occupied apartments would be built, which would not be able to solve the problem of affordable housing. Instead, she suggested that only social housing should be built in inner cities with a tight housing market from now on.

A new entrepreneurial spirit?

The leading association of the real estate industry, the German Property Federation (ZIA), called for a new entrepreneurial spirit at the kick-off meeting of the Alliance for Affordable Housing. According to President Dr. Andreas Mattner, this should serve as a response to the accumulation of the pandemic, Ukraine and climate crisis.

“Construction costs have exploded to an unprecedented extent, construction companies are barely able to keep to their contracts, interest rates are skyrocketing, subsidies are being cut and efficiency requirements are set to increase. And all of this with a need not just for 400,000 new apartments per year, but – due to the admission of hundreds of thousands of refugees – for 500,000 to 600,000 apartments. It is no longer possible without bold cuts: We need a regulatory freeze and the suspension of time-consuming approval procedures. The commendably swift extension for refugee buildings is a very good first step. Next, we need a banking summit to find measures to counter the rise in interest rates and a materials and supply chain summit. The real estate industry must be able to participate in these crucial decisions,” says Mattner.

“Furthermore, we need a degressive depreciation as well as serial and modular construction that is not only talked about, but also implemented across the board. The challenges seem almost impossible to solve – but crises also present an opportunity for change and we all have a duty to push for this,” he added.

A house for contemporary art

Almost 50 years ago, the then still very young publisher Gerhard Steidl had the idea of building an exhibition house for contemporary art in Göttingen, the city of his birth. Now the Kunsthaus Göttingen is being realized Gerhard Steidl creates book art at the highest level. His aim – whether fashion, art or literature – is to bring the ideas of artists […]
