Germany and its roofs – this is not a showcase story. It is only in recent years that German municipalities have begun to rethink green and utility roofs. Nevertheless, there is still a lack of know-how everywhere – including among planners – about what a roof can actually achieve and what it will have to achieve in the future, especially in the wake of climate change. In the June issue of G+L, we use remarkable roof projects to show where Germany needs to go in terms of roofs: upwards.

With this issue, you will also receive the G+L special issue “BAUDER” with the topic: Roof of the future.

In an interview around three years ago, Dr. Gunter Mann, President and Managing Director of the Bundesverband Gebäudegrün e.V. (German Green Building Association), told us that Germany was the world leader when it came to greening buildings. This did not mean that Germany did everything brilliantly, but that no other country could match the overall package (greened areas, municipal funding instruments, specialist regulations, specialist staff, experience). In May 2024, Gunter Mann confirmed this statement again when I asked him. Nothing had changed.

I already found it hard to believe this statement in 2021, and I still do. Not because I doubt Gunter Mann’s expert opinion, quite the opposite. I just can’t reconcile his statement with the lack of German lighthouse projects. What does Germany have to show for itself in terms of green buildings? There is the sometimes highly controversial Kö Bogen II in Düsseldorf by Ingenhoven and now the green bunker in St. Pauli by Landschaftsarchitektur+. After that? Nothing for a long time.

Lighthouses can be dazzling – my own perception shows that. At the same time, if our cities are so good at green buildings and have this USP, then we need to make more use of it for ourselves. After all, according to the BuGG market report, the area of green roofs in Germany increased by 8.7 million square meters to a total of around 160 million square meters in 2022, and almost every major municipality now has a green roof strategy. That’s pretty impressive. And it shows: Municipal awareness of the importance of roofs is there. But the media and social attention is lacking.

And our roofs and façades need this exclamation mark now – now more than ever. Climate change. Heavy rain. Heat waves. The roof of the city of tomorrow must look different. However, it cannot and must not only be about the green roof, the green façade (with perhaps a little PV here and there), but also about how we can use roofs in particular – the previously dead spatial capital of our cities – better, differently and in a more versatile way.

Playgrounds, parks, skate parks, bouldering areas, urban forests. The corresponding projects are already being implemented in the private sector. Now we need to make these projects accessible to the public and consumer-free. We need to broaden our horizons here – and I hope this booklet will help us to do so.

The booklet is available here in the store!

Our latest issue, the May edition, is all about bridges. The second part of the city special.

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 […]
