New Building On Aktienstraße

Mülheim an der Ruhr

The height and position of the new building is aligned with its urban surroundings. The front edge is flush with the neighboring building. In order to make the façades facing Aktienstraße more prominent and to increase the visibility of the building on the site, the volume is planned across the entire width of the plot.

A steel construction with a timber frame façade is planned, which will be curtain walling. This materiality is not only sustainable, but also creates a better quality for the employees working there thanks to its tactile feel.

Conceptually, the volume is organized in a strong base with a “flying” upper block to create a new scale on the very different fronts (e.g. fast train connections, industrial character with large and less street-going buildings). Instead of one large block, the concept focused on working the volume in its height and in two main parts, with less weight due to the “aerial plane”.

Usage

The allowance for a large market activity attracts a high contingent of users to the site. This is reinforced by the office workers and visitors to create a lively place.

The emphasis on the aerial floor of the parking speaks to the less human scale of the railroad line and the industrial buildings, allowing a new and elevated view of the surroundings. The two-story commercial space includes a storage area, mechanical rooms, restrooms and circulation cores. Intended as a large retailer, the design of the ground floor and first floor forms a self-contained and strong base, which connects to the office building via the equally self-contained and external access cores.

The upper four-storey volume will be an airy and transparent body for office use. The external circulation cores are important for the flexible use and organization of the floor plans.

Open spaces

The site is higher than street level. For this reason, the entrances to the project site are based on the gradient of the current access road. The ramp to the parking deck is planned as an independent element and sits on the straight level of the access road.

In addition to the ramp, entrance areas, technical and delivery areas as well as the required parking spaces for bicycles are planned. A smart pool is also planned for flexible mobility. Together with the public transport system, the parking deck meets the number of parking spaces required for office buildings and businesses.

Berlin

The commercial building and former hotel “Pariser Hof” was built in 1907 on the corner of Friedrichstraße and Kochstraße in today's Kreuzberg district by architect Ludwig Engel. The building is characterized by its strikingly ornate, decorative Art Nouveau façade and the accentuated round corner risalit. The building remained largely undestroyed during the Second World War, with only the striking corner tower above the risalit and a large barrel dormer with stone surround falling victim to a roof fire.

The sudden peripheral location of the property, due to the division of the city at the so-called Checkpoint Charlie, led to a significant redesign of the first floor façade for cinema use after the war. Most of the high and wide shop windows were bricked up and a projecting canopy was installed. Angular, sheet-metal dormers were also installed in the renovated roof truss.

The building is listed as an individual monument and is to be completely renovated for further commercial and office use from winter 2023 to summer 2024.

The planned general refurbishment essentially comprises the dismantling of the closed cinema front and the canopy on the first floor, the revision of all office floors with new partition walls and sanitary cores, as well as new building services. In addition, the roof will be renovated, both structurally and in terms of its appearance and character, with a continuous window strip running along the roof slope and a sheet metal skin.

The existing ornamented sandstone facade will be cleaned and repaired true to the original only where technically necessary. In the area of the ground floor (as a result of the cinema conversion), careful additions are planned in the area of the supports.

In line with the restrained redesign and continuation of the historical monument on the façade, an equally sustainable and ecologically responsible new concept is also planned for the interior. As far as possible, the substance will be preserved or sensibly upgraded. This applies in particular to the box-type windows, the historic staircases, the elevator shaft, the light well and the ceilings. The same principles apply to the new building services: As much as necessary, as little as possible. For this reason, a minimum of system technology for heating, cooling and ventilation is installed. Windows that can be opened everywhere in combination with external sun protection allow for a minimization of technical resources and sustainable use.

Conversion + Renovation Office Complex

Bottrop

On the 8,500 m² site in downtown Bottrop, there are two buildings that were previously used as office spaces. The southern "RAG" building was constructed in 1955 and was extended with an additional section on the northern side in 1972.

After a comprehensive renovation, both building sections will primarily be used for residential purposes. A mix of apartments, maisonettes, and communal living spaces will address various housing needs. Office use will be organized over six floors in the "RAG" tower.

The external appearance of the "RAG" building can be preserved even after renovation, and a residential outdoor area will be created on the roof. The 1972 building will be enhanced with balconies and a ventilated wooden facade.

Decathlon

Herne

The goal of the Decathlon Herne project was to redevelop the Hibernia industrial site in Herne with a new building to strengthen the economic structure and improve ecological qualities.

The significance of the building arises from a strong articulation of the overall volume. This articulation is created by shed roofs. The sheds provide natural lighting to the interior from the north and offer the possibility of natural cross-ventilation, thus eliminating the need for mechanical ventilation.

To regulate the surface water balance, the areas between the shed roofs are greened and equipped with a high substrate layer. These green roofs capture the surface water, allowing it to evaporate from there. Excess water is directed to a drainage canal located at the entrance. The canal is connected to the natural stream system of the surrounding area.

The primary structure is a composite system of reinforced concrete and steel. The steel trusses are widely spaced to keep the interior free of columns. The exterior facades consist of industrial aluminum sheeting and pressed glass, which ensures maximum illumination. Administrative offices are housed in a two-story building block on the north side of the building.

Grammer Office HQ

Ebermannsdorf

The new headquarters of Grammer Bürostühle GmbH is nestled like a rock in the Bavarian Forest. Grammer produces high-quality office chairs and cinema seats in an "on-time" production system.

The building complex is divided into a production hall and an administrative building (head office), which are connected by a bridge. They are flanked by black, massive "rock" walls. The outwardly rugged architecture, in the style of Land Art, reflects the surrounding forest landscape. The buildings blend into the environment through scattered plantings of native trees.

The structural framework of the 6,700 m² hall consists of a galvanized steel structure made of trusses and fixed steel columns.

The facade is made from aluminum sandwich panels. The end facades feature profiled architectural glass with thermal insulation coating, combined with an anodized post-and-beam construction.

H+H order picking building

Höningen

A gentle slope, with an industrial area at the back and a wide view of the Soester Börde at the front—an appealing yet challenging situation. The neighboring structures are large and faceless, spread out across the area.

The theme of the new building for H+H is the edge of the slope—seemingly sinking into the terrain, the interior features two levels: a continuous ground floor for order picking and, on a gallery level suspended from the roof, zones for storing all necessary packaging materials.

Offices and an apartment are located on the single-story side of the building, offering a view of the landscape. The structural framework is designed as a mixed construction—wood (roof trusses, wall panels) and steel (columns) form an architectural unit.

Wulf-Hefe-Gallery

Werl

The goal of the "Hefe-Galery" project is the redevelopment of an inner-city brownfield site, whose previous use as a brewery became obsolete with the demolition of the building.

The new building compensates for the deficit in event and dining spaces. The differentiation of the retail structure attracts new external customer traffic, thereby strengthening Werl's inner-city retail landscape beyond just the immediate location.

The limited land resource has been occupied by a two-story building that aligns with the local scale. Retail, dining, logistics, and administration are located on the ground floor, with parking and technical facilities on the upper floor, as well as event spaces on both levels. Green areas are incorporated into the rooftop.

The primary structural framework consists of a prefabricated reinforced concrete construction with spans of 10x10 meters on the ground floor and 20x30 meters on the upper floor. After completion of the second construction phase, the usable area will be approximately 12,000 m².

The building features a central control system for optimized resource management. Rainwater is collected decentrally, stored centrally in a cistern, and then directed into a greywater system. High visitor traffic is managed through a complex supply and disposal concept that takes into account day and night cycles to minimize impact on the surrounding neighborhood.

Competition G Data

Bochum

Creativity and intellectual flexibility, combined with proactive execution strategies, create their own markets. To accomplish this task, a constantly motivating environment is needed—this includes areas for focused work as well as zones for relaxation and communication—specific spaces for rationality and emotion. Close connections, a continuously regenerating network of information flows, and diverse available knowledge—this is how G DATA presents itself to the external observer.

The image of neural synapses comes to mind. We want to anticipate this association in the building structure.

Floor Plan

This results in a layout with two buildings: a four-story office building for "rationality" and a connected single-story pavilion for "emotion." Terraces are offered on its roof, as well as a landscape loggia facing the valley, adjacent to the restaurant areas. The single-story pavilion houses the academy, lounge, bar, and restaurant, as well as service center rooms along its edges.

The floor plan is designed as a fluid space. Usable areas and traffic zones are not separated but form a unified space, which is fully usable. This approach enhances circulation areas.

Urban Design

The four-story office building is constructed along Lise-Meitner-Allee, forming the gateway to the district. The pavilion, with its inserted structures of varying heights, follows the planned street and opens up on the first floor towards the valley. On this side, it is elevated as a belvedere.

Facades

The facades of the office building are designed homogeneously around the entire layout. The closed sections cover 50% to 60% of the facade, depending on orientation, and are clad with terracotta. The transparent sections are designed as casement windows integrated into a vertical line structure.

Competition Volkswohl Bund Insurance

Dortmund

Volkswohl Bund Insurance aims to secure its success for the future. To achieve this, a new building with modern workplaces and functions is necessary.

Urban Planning Concept

The block perimeter at Chemnitzer Straße – Hohe Straße – Südwall will be closed. The existing street-level base floors will be demolished, and the high-rise will be exposed and accessed via an appropriate, forecourt. This square opens up the city access from Hohe Straße towards the city center and visually connects the city center with the adjacent residential area. A place with vibrant qualities will emerge. The courtyard will be extensively greened and kept free of vehicular traffic.

Design/Architectural Concept

The building will be centrally accessible—a two-story entrance hall serves as the starting point for straightforward navigation within the building. From here, all functional units are directly accessible. Two building wings will be constructed parallel to Südwall. The space between these wings will be designed as a water feature and will be generously visible from the entrance hall.

Material

The new building will be bright! The glass facades are full-height and alternate with stainless steel surfaces on the solid parts. The roof surfaces of the underground garage will be greened. The floors in the entrance hall and the dining areas will have natural stone coverings, while the office areas will feature continuous textile floor coverings. The skylobby will have a wooden floor that extends out as a terrace into the roof garden. Walls adjacent to the facades will be made of drywall. Interior walls leading to the corridors can be transparent or opaque in certain areas or covered with wood.

Construction

The structural framework—columns and flat slabs—will be constructed from reinforced concrete. The existing ceiling structures of the existing building will receive a suspended cooling ceiling with a clear room height of approximately 2.85 meters. The conference room will be opened up over two floors, allowing for the seamless integration of technical infrastructure for climate control and media. The roof of the dining area will be designed as a sloped concrete slab, with parts of it being greened.

Principles of Technical Equipment

Minimizing cooling and heating energy requirements, maintaining low operating costs, high daylight utilization, high thermal comfort, and cost-efficiency.

Outdoor Areas

The property will be significantly built upon. The roof of the underground garage will be greened and accessible. Terrace areas in front of the dining areas will be paved or covered with wood. All plants will have shallow roots and be suitable for flat roofs—trees and hedges will have separate planting elements. The courtyard between the building wings will be covered with a pond. Bamboo will be placed in special planting elements within the water area.
