The vision was to create a modern media house for Spiegel’s employees and the surrounding city. An icon of high international standards with focus on openness, communication and transparency” Louis Becker, DIRECTOR AND PARTNER, HENNING LARSEN ARCHITECTS
THE VISION - a window to the world
The vision
Der Spiegel is Germany’s most influential news magazine and today has over 6 million readers.
Spiegel is one of the largest media houses in Europe and with its new headquarters in Hamburg, the Spiegel Group has got one of the most prominent locations in the new urban quarter of HafenCity by the Elbe. For more than 40 years, the world-known news magazine, Der Spiegel, has been located in Brandstwiete, Hamburg, in a building very much characterised by Verner Panton’s colourful pop art design. Spiegel Online and Spiegel TV have been situated at other locations in the city, but now the three divisions are consolidated in one building – the new Spiegel Headquarters. The new headquarters has a prominent location in the inner habour of Hamburg and offers a distinctive design with its own unique architectural expression. Together with the office building, Ericus-Contor, which forms part of the complex, Spiegel Headquarters rises from a red tile base – above which floats a bright, transparent building volume of glass, steel and concrete.

Spiegel Headquarters is designed by Henning Larsen Architects and is characterised by its clear focus on contact points, meeting places and communication. In combination with its high architectural quality, clear connection to the urban context and holistic sustainable design, the project is designed to meet the needs and requirements of a modern media house. This was also the reason why the project was selected as winner of the international competition with 13 participants in 2007. The new headquarters covers 30,000 m2 and houses 1,100 employees. The bright, transparent design supports the work processes in the editorial offices, documentary department and publishing division and the interior layout provides room for concentration, communication and dis-

semination. The individual floors are connected by stairs and footbridges rising across the central atrium space. The large central window of the building, ’Fenster zur Stadt’, creates an active dialogue between the activities of the media group and city life. The fifth floor comprises a café very much inspired by the interior design of Panton in the previous Spiegel Headquarters from 1969. The original red pop art environment creates an inspiring, evocative gathering point for Spiegel’s employees. From the outside, it stands out as a redorange field in the facade facing the city. The vivid Panton colours closely connect to Spiegel’s identity and have been re-used several places in the building.

One of the great qualities of HafenCity is the proximity to the water. It has been an essential focus point in the design process that the new Spiegel Headquarters not only offers the employees an attractive office environment but that the building also contributes positively to the public urban space. The building connects the old Hamburg and the new urban quarter of HafenCity and creates a vibrant urban space with squares and recreational spaces along the Elbe. As one of the first and most sustainable buildings in Hamburg, Spiegel Headquarters has been awarded the prestigious award ’Hafencity Umweltszeichen Gold’ – a forerunner of the German certification standard, DGNB.

The vision
An open invitation
Interview with architect Louis Becker, Partner and Director at Henning Larsen Archtiects and Adjunct Professor at Aalborg University. Henning Larsen Architects has designed commercial buildings all over the world. The buildings are characterised by a distinctive design based on the objective to strengthen the corporate identity and an active use of daylight, which contributes to creating an attractive and efficient work environment. What characterises successful commercial buildings? A successful commercial building supports the company’s dynamics, culture and image. The design cannot bring about a change in itself but it plays a significant role by providing the framework for change. Commercial buildings should have a flexible design, allowing for future work and innovation processes to unfold with no limitations. Many projects have an agenda where architecture is a tool for change, and a commercial project always offers some kind of in-built change – for instance a new organisation or a new way to work.
10 |
The building should contribute to motivating the employees and creating synergy across departments – generating new ideas and thus added value for the company. It should offer room for concentration, cross-disciplinary collaboration and dialogue and comprise areas for both individual and group work. Likewise, it is essential that the physical framework creates a sense of community and affiliation with the company. Flexibility should be a decisive element in the design process from day one to ensure that the building layout is adaptable to future organisational developments. Instead of creating barriers, the building should create community and contact between the employees – encouraging informal meetings, dialogue and knowledge sharing. The employees should be able to see and quickly establish contact with each other to discuss ideas etc. Metaphorically speaking, the building should offer a never expiring invitation to contribute.
HENNING LARSEN ARCHITECTS | SPIEGEL HQ
In what way does the design create value for the users? Naturally, the building should create value for the business. It is a management tool. However, the building also provides the company with a clearer profile. In the design stage, many details need to be decided upon – a process that naturally brings up the values and corporate culture of the company. Thus, the process is also an opportunity for the company to change old habits and consider whether the business could be organised in a different way. Sustainability has been an important theme in architecture in recent years and has marked a significant change. It has become important to respond to the international political scene on which climate change and use of resources are top of the agenda. Many organisations also wish to demonstrate that this is a theme that they take seriously – and in this context, architecture is a powerful tool. We are currently working on a number of commercial buildings worldwide with extremely high ambitions as regards the corporate responsibility that the completed building should demonstrate. A lower energy consumption, fewer
sick days among the employees and lower operational costs are some of the aspects that not only entail financial savings for the company but also contribute to strengthening its image significantly. In general, which qualities characterise the commercial buildings of Henning Larsen Architects? We base our design on the meeting and interaction between people. At the same time, we strive to create buildings that relate to the surrounding context – not only the city, landscape and climate but also the culture and the society that they form part of. Our objective is not to develop icons only offering a fancy design and a short, inspirational ‘kick’ – our commercial buildings should create long-lasting value for clients and users. All our buildings offer their own unique expression developed in collaboration with the client and relevant user groups. One of our main architectural beliefs is that commercial buildings should support knowledge sharing and social interaction across the organisation. Thus, the buildings most often comprise large, synergy-creating spaces.

An icon in HafenCity
Spiegel Headquarters has a distinctive design and stands out as an icon marking the entrance to the new urban quarter of HafenCity and at the same time providing Der Spiegel with a clear identity in the city. HafenCity is the new urban quarter of Hamburg. Situated by the Elbe, HafenCity is one of the largest urban development areas in the world. When it has been fully built-up, Hamburg is expected to grow by 40 %. Everywhere in HafenCity, the proximity to the water is a central quality. The triangular plot of Spiegel at Ericusspitze is surrounded by water on two sides and has a prominent location in the area. The central location at Ericusspitze in HafenCity makes the new headquarters a new landmark in Hamburg as a whole. Spiegel headquarters marks the entrance to HafenCity and on the equivalent plot to the west, you find the new Elbphilharmonie designed by Herzog & de Meuron. Together, the two buildings mark the border between HafenCity and the old city centre. Ericusspitze represents the urban transition from the old, low industrial buildings on the one side of the water and the densely built-up area and tall buildings of HafenCity and the old district, Speicherstadt, on the other side of the bridge. The new building complex consists of two overall elements: Spiegel Headquarters and Ericus-Contor, which will house various commercial tenancies. The buildings rise from a joint base, which ’folds around itself’ and creates two
raised platforms on which the two buildings are situated. In the gap between the square and upper levels of the platforms, the public functions of the buildings are situated behind a transparent glass wall. In front of this, a large broad staircase encourages people to sit down and have a break on the square and thus contributes to creating a vibrant urban space for citizens and tourists. Two large, white glass cubes with double facades rise from the shared tile base. The outer facade layer consists of glass while the inner layer is made up of white metal with modular, room-high windows. The Spiegel building, constituting the largest volume, faces the city and the bridge, Oberbaumbrücke. Here, the recessed facade creates a large opening stretching from floors 3 to 12. This ‘window towards the city’ – ‘Fenster zur Stadt’ allows the citizens to follow the in-house activities and provides the employees with a view of the city and world they are describing. Ericus-Contor is based on a similar concept with homogeneous facades oriented towards the inner square and a large opening towards the harbour, which creates visual contact between the building courtyard and the planned Lohsepark on the other side of the harbour. Thus, the design and orientation of the two volumes create a unique connection between the inside and outside – between the buildings and the public urban space.

Spiegel HQ adds value to the entire city
Interview with Project and Design Manager Klaus Troldborg
How has the city and the location on Ericusspitze influenced the building design? The design of the new Spiegel Headquarters is based on the urban context. A location on such a central plot in the city requires a distinctive building – a distinctive architectural design. Ericusspitze marks the entrance to the new urban quarter, HafenCity. At the same time, the building represents the transition between old and new – between the old Hamburg and HafenCity. The building is made up of three elements: two white glass cubes placed upon a joint base. With its scale and tile clad surface, the base connects to the adjacent historic area of Speicherstadt, while the white cubes relate to the scale and materiality of HafenCity.

The building has a very attractive location on Ericusspitze, in the centre of the city and with water on all sides. Thus, it has been important for us not only to develop a new headquarters for the Spiegel Group but also to create a place of value for the entire city. This means that the architectural focus has not solely been on the two buildings comprising the offices of Spiegel and Ericus-Kontor, but also on the continuous urban space created between the buildings – a large arrival square on the one side and a public plaza to the south. We hope that people will gather on the large stairs leading to the water or at one of the many cafés and other outward functions situated on the ground floor of the building.
HENNING LARSEN ARCHITECTS | SPIEGEL HQ
How has Spiegel’s identity been incorporated into the design? The objective of the project was to consolidate all functions of the Spiegel Group under one roof. In this connection, it has been central to us to develop a design that enhances the sense of community and identity for the employees and supports the contact between the various departments. The circulation in the building is centred around the central space – the atrium – where footbridges and stairs create dynamic shortcuts between the various departments up through the building. The atrium is the identity-creating
space in the building and sets the stage for communication and informal meetings between the employees. Flexibility has been another focus area in the design process. It has been important for us to design a building that meets today’s work place requirements, but which is also adaptable to the continuously changing agendas in the media business. All special functions such as the cafeteria, conference area, television studio etc. are placed in the building base on the ground floor and first floor, while the office functions are situated on the third floor and up. The flexible design of the departments allows for them to be extended or re-arranged as needed.

An icon in HafenCity
As regards the Spiegel’s identity in Hamburg, our intention has been to build on the position of the previous headquarters as an architectural landmark in the city. With the large ‘Fenster zur Stadt’, our ambition has been to establish a close connection between the Spiegel Group and the city – to give the citizens in Hamburg an insight into the work processes of the media group and likewise provide the employees with a view of the world they are describing. What has sustainability meant for the building design? The sustainability certification of HafenCity – which could be considered a forerunner of the German DGNB standard in green building – takes a holistic approach to sustainability and incorporates everything from energy and resource consumption through economy and indoor climate to social aspects. The Spiegel Headquarters is pre-certified for a gold medal, which means that at least four out of five categories meet the requirements for gold. Thus, the building is one of the most sustainable large-scale buildings in Germany. Looking at the social aspect, the building actively contributes to city life by providing public access to the site and offering a number of public, outward functions on the

ground floor. Regarding energy consumption, the building operates with both visible and invisible solutions. Firstly, we have created a compact volume and a facade that reduces heat loss and provides ample daylight. The so-called double-compact facade provides effective sun protection and allows for employees on all floors to open the windows. To mention one of the more invisible solutions, the building is heated and cooled by means of the exposed concrete slabs in which embedded cooling coils are connected to a geothermal facility. This combined with a well-insulated facade and use of treble glazing makes it unnecessary to have radiators in the building – which again reduces the energy consumption and improves the indoor climate. Sustainability has greatly influenced our approach to the building design as a whole, and it has been an interesting challenge to develop architectural solutions that meet the high requirements of HafenCity’s gold medal. Green building is here to stay, and if sustainable solutions are incorporated correctly from the beginning, they are no hindrance to achieving buildings of a high architectural quality!

The ambition has been to create a strong identity for the entire Spiegel Group based on the key words communication, flexibility and transparency. The design of Spiegel Headquarters aims to create a strong sense of community for everyone in the organisation. All employees should feel part of a very special work place, and the interior layout provides the setting for informal meetings between the employees – and thus the decisive synergy and cross-pollination between the various platforms of the Spiegel Group. When entering the building through the main entrance, recessed in the gap below the floating tile volume of the base, you pass the reception and the building opens up in a large atrium rising up through all 14 floors.

A large stone-clad staircase in the atrium leads to the first floor, which – in addition to sound studios and a staff fitness centre – comprises a large meeting and conference facility. This section faces the square and opens up towards the view by means of large windows and a loggia where you can step out to enjoy the view. Interior cube
The design of the atrium space links the various divisions across floors and encourages for communication and informal meetings between the employees. Glass lifts are available in both ends of the atrium and a varied sequence of stairs and footbridges rise across the atrium from floors 3 to 12.
If you move further up through the part of the building whose exterior appears as a white glass cube, you arrive in the office section – characterised by open balconies along the walking lines around the atrium. It is possible to establish offices along the entire exterior facade. A flexible wall system allows for the distribution of closed offices of various sizes and open-plan offices to be changed as needed in the future.
The special functions of the building are situated in the base whose central atrium is clad in natural stone. The ground floor comprises a television studio and staff cafeteria with direct access to the public square in front of the
The walls towards the corridor consist of a combination of oak doors and panels of glass and wood, respectively, which makes it possible to meet the specific requirements of the users – whether they need transparency or privacy.

An active meeting place
The most open functions of the building are primarily located to the north and south with direct access to the atrium, while the divisions requiring more peace and quiet are placed to the east and west, where a core of service functions serve as a ‘buffer’ to the atrium. The atrium is the heart of the building and the place where people meet and follow the activities in the building. Its varied two and three-storey spaces open up to the city and make the view of Hamburg a central quality all the way up through the building. Materials and colours The materials and colours of the building have been carefully selected – with a view to achieve a strong sustainable profile and express the distinctive building design in the best way possible. On the exterior, the heavy, tile clad base creates a beautiful contrast to the smooth filigree glass cube. The expression of the double facade changes between reflection in the outer glass layer and a more deep expression –where the inner facade’s white lacquered metal and room-high windows with dark wooden frames stand out distinctly, depending on the time of day and orientation of the facades towards the sun.
surfaces and white metal ceilings. Wooden handrails on the front edges of the balconies and footbridges, wooden doors and wood panelling on the walls towards the corridors and atrium provide the interior with a bright and embracing atmosphere – and a certain Scandinavian touch. The use of glass panels on the office walls creates transparency and lets the light pour in the atrium through both facades. The bright and neutral colouring contributes to bringing the individual employees into focus. When entering the building and particularly the large atrium, you will be met by the employees moving across the balconies along the atrium or across the footbridges and stairs. As a contrast to the white colour, selected places in the building feature contrast colours in a scale ranging from yellow over orange to red – colours that both refer to the colour of Spiegel’s logo and to Spiegel’s long history of applying Werner Panton’s colouring. In the triple-high room towards ’Fenster zur Stadt’, elements from the old Spiegel cafeteria are reused in the new staff cafeteria and thus emphasise and carry on this history.

An active meeting place
Two worlds meet Interview with project architect Martha Lewis Which role has Henning Larsen Architects played in the interior design of Spiegel Headquarters? Henning Larsen Architects has been responsible for the interior design of the headquarters, including the selection of materials. A special characteristic feature is the 13 footbridges in the atrium, creating a dynamic connection between the third and twelfth floor and also the adjacent café/lounge – a triple high space forming part of the prominent large window facing the city, ’Fenster zur Stadt’. The lounge is a creative re-installation of Verner Panton’s original, colourful pop art design developed specifically for Spiegel’s previous Hamburg headquarters in 1969. The common wish of Der Spiegel and the preservation institution of Hamburg was for the new café to feature elements

of the original design. Thus, we have re-used the colours, lamps, chairs and tables of the old Spiegel Headquarters – making two worlds meet: the colourful, expressive Panton universe on the one side and the more simple expression characterising the design of Henning Larsen Architects on the other. In all the remaining parts of the building, focus has been on creating a light, open and transparent environment by primarily applying bright colours and natural materials – adding highlights from Panton’s palette of colours to create a special atmosphere and experience in the more hidden parts of the building. We have put great emphasis on not bringing everything on to ‘the cover’, but instead giving the users – Spiegel’s employees and visitors – the
HENNING LARSEN ARCHITECTS | SPIEGEL HQ
opportunity to ‘leaf’ through the building and find their way to the areas highlighted with color. As an example, the primary escape routes are marked by a vivid colour very much influenced by Panton. What characterises the design and decoration of the red café lounge? The Panton café designated for the employees of the media group has a distinctive expression clearly visible from the outside in the evening and appearing as a bright orange field in the large ’Fenster Zur Stadt’ in daytime. From the footbridges in the atrium, you enter a room that – despite its transparency and high ceilings – resembles an authentic 60’s lounge with coloured lamps and soft velour. The 100 m2 high-ceiling lounge features tables
and chairs from the original café supplemented with new Panton furniture. The floor is covered with the classic red-pattern Panton carpet and on the high back wall, we have re-created a mosaic of shimmering light panels and upholstered acoustic pyramids. Hanging from the ceiling, you will find groups of the classic red flower pots used by Panton in the original Spiegel cafe. Panton’s design from the 1969 focused on creating a relaxed, cave-like atmosphere of colour to support an inspiring work environment for the employees. Henning Larsen Architects’ design is not characterised by the same compressed spaces, but we have continued the spirit of his work and taken a curious and respectful approach to the three-dimensional and textural character of his design.
SPIEGEL HQ | HENNING LARSEN ARCHITECTS

AN aCTIVE MEETING PLACE
An important element of the process has been to create a smooth transition between the lively colours of Panton and the softer, natural materials for instance found in the atrium. How has it been for an architect with a more minimalist tradition to work with such expressive shapes and colours? For the café, the challenge was to achieve a complete Panton universe in a 2011 building. By means of a creative re-use of Panton’s dynamic, colourful elements in the ‘Fenster zur Stadt’, we have rooted Spiegel’s own design history in the new headquarters. It was an extremely inspiring assignment to get the chance to work with classic pop art on such giant surfaces. A general use of accent colours throughout the building has formed part of our design tradition for a long time.
30 |
We often work with incorporating colours and textures in large spaces, and the meeting between simple and more powerful elements has always been part of our architectural approach. It was very exciting to make the two worlds and eras meet for the Spiegel Headquarters. To make the original designer’s work and a strong contemporary design delicately interact. Visiting Hamburg recently, it was fantastic to see how the building actually works – and experience how the light filters down through the atrium, and how the employees use the footbridges across the floors for informal meetings just as intended. Likewise, it was a very strong physical experience to move through the building – the many zigzags of the footbridges give you a sense of physically interacting with the building – almost like dancing!

FOCUS ON SUSTAINABILITY
Focus on sustainability
Sustainability has been a central and significant aspect for all involved parties from the beginning of the project. Early on in the process, it was thus decided to design the building in accordance with the gold medal requirements of the local certification system, ’HafenCity Umweltzeichen’. As is the case for the subsequently introduced certification system in green building, DGNB, ‘HafenCity Umweltzeichen’ operates with a broad definition of sustainability, including social sustainability, energy consumption and a conscious use of materials. Energy consumption To achieve a low energy consumption of 80 kwh/m2/year, a number of sustainable solutions have been incorporated into the design of the building. The facade of the glass cube is a so-called ‘double compact facade’ whose outer layer protects a ventilated cavity comprising flexible and effective solar protection. The interior facade offers a high degree of insulation by means of extra insulation in the closed panels and use of three-layer glass in the large windows.
34 |
The exact sizes of the windows, solar protection unit and curtains have been carefully matched to find the right balance between the U-value of the facade, the thermal load of the sun and inflow of light in the offices – and thus minimise the energy consumption for heating, cooling and artificial lighting. All large double-leaf windows of the building can be opened individually and thus contribute to increasing the flexibility and comfort of each employee. Likewise, the solar protection units can be individually controlled. The temperature in the building is controlled through water-bearing pipes embedded in the concrete slabs. In that way, the mass of the heavy building parts is used to cool and heat the office spaces, which thus feature exposed, rendered concrete ceilings. To ensure a high degree of flexibility, the ceilings are fitted with thermo sockets to
HENNING LARSEN ARCHITECTS | SPIEGEL HQ
which cooling coils can be connected to adjust the temperature in the individual office spaces. The cooling coils are connected to a geothermal facility. The air supply channels of the ventilation system are embedded in the corridor floors of the individual offices, while the exhaustion channels are incorporated in the ceiling. The channels are connected to an efficient heat recovery facility on the roof – another important element in the energy optimisation of the building. Water
Materials All materials applied have been thoroughly examined. Products containing PVC or other blacklisted substances have been avoided, and the materials’ ability to create a good indoor climate has been measured. The specific requirements for the degasification of substances (TVOC less than 1.5 mg/m3), elimination of biocides and formaldehydes and halogen-free fire protection are met.
Focus has been on achieving water savings by means of water-saving fittings and use of grey way for flushing toilets, watering flowers, cleaning and washing.
Mechanical ventilation and the possibility to open the individual windows ensure a high air quality throughout the building.
The percolation of rainwater on the plot has been reduced by means of rainwater collection and by the partly green roof surfaces. Facade materials that could release heavy metals to the rainwater have been avoided.
A minimum of 20 % of the functional areas should be suitable for allergic people, which means that all materials and solutions have been tested in relation to how easy they are to clean.

SUSTAINABLE GOLD MEDAL
‘HafenCity Umweltzeichen’ applies a broad definition of the concept of sustainability and has divided the different themes into five categories in which specific requirements must be met to obtain silver or gold. At least three out of five categories must be met to achieve gold. The objective of the Spiegel project has been to achieve gold in four categories. The project has been preapproved for gold but the final granting will not take place until the completed building has been tested for meeting the requirements. Hafencity Umweltzeichen is in many ways a forerunner of the German certification system, DGNB, comprising a broad perception of sustainability that includes environmental, social and economic issues.
