Riem Arcaden – Office Mix

Germany’s leading office logistics service provider is creating a special ambience for its employees. Klaus Mix and Peter Köhnlein not only offer their customers solutions for their working worlds, but also keep their own team working in an attractive ambience. HEIKAUS implemented their open-plan office with 18 workstations at Willy-Brandt-Platz 3 in Munich in a construction time of only 4 weeks. This short period had to suffice to completely strip and re-design the area of 350 m² into a highly-functional space that keeps the entire team comfortable.

Hotel Schwanen

Another room was to be planned in an architecturally attractive manner on the 250 m² of Hotel Schwanen. The target was achieving greatest diversity for many different events. Festivities, meetings and seminars alike were to use the attractive top floor from May 2019 onwards. Like the other rooms of this hotel, the “swan”, as the hotel’s namesake, was to find “its place” in the area plans and the room concept.

Heikaus acts internationally.

HEIKAUS was charged with project management and implementation for the congress centre in Tashkent (UZB). The result is presented with an extraordinary room impression.

Exquisite materials such as genuine mother of pearl, stucco plaster, Swarovsky wallpaper, marble and ebony reinforce this impression.

The special shapes of the ceiling and the indirect lighting emphasize the room’s height and provide a feeling of generosity.

ADAC phone centre

After many successful projects, tenant development of the ADAC phone centre in Stuttgart once again brought us together.

As before, HEIKAUS worked as the project-managing company and took care of all tasks arising for the building project from light planning to implementation and project control. This enabled us to effectively plan interior development and to implement it efficiently.

The room-acoustic requirements to a phone centre that has to be available to customers around the clock were a special feature in this project.

Dekra Stuttgart-Vaihingen

Every tenant development project is unique.

Every result is one of a kind.

Industry-specific requirements are developed and consideration in close cooperation with our customers.

We took care of planning, execution and project management for the new Dekra branch in Stuttgart.

The furnishing colour concept is aligned with Dekra’s green. Light planning was another important part of this interior design.

Starbucks Zürich Airport

At the Zürich airport, we took care of project management and execution of the tenant development for the first reserve bar of Starbucks.

The interior development was completed in only four weeks. The result is now presented on an area of 320 m² with a completely new design ad furnishing concept.

The short conversion time and the “Airport” site posed some challenges to our team, of course. Precise logistical planning made it possible to implement the concept in time.

Sabine Knaupp

"We felt supported very well even in the early stages of the planning phase. Our wishes to design and customer requirements were implemented outstandingly. The new design concept has a much fresher appearance that our customers love a lot. Execution was extraordinarily on time and precisely according to the plan. We as the builders didn't have to take care of anything at all."

"Our targets were put into practice without deviation. It couldn't have gone any better. Even small rework was completed unbureaucratically and quickly."

ADAC Baden Württemberg

Michael Treuter

"We are very happy. Our long cooperation means that planning and interior development have become very quick and uncomplicated. Both parties know what they need to do.
