Welcome to RWI4!

The RWI4 twin towers emanate a silver glow as they rise over Düsseldorf. Right in the heart of lively and trendy "Lorettostraße" and surrounding district, you have the opportunity to rent office space from 300 square meters (3200 square feet). A great number of additional services and amenities make RWI4 the ideal international business location.

Modern Architecture!

In the end, it is personal taste and individual preferences that decide whether a certain building is perceived as beautiful or not.In RWI4’s case, the elegant façade, the twin towers’ incomparable charm and the multifunctional "socket floor" are decisive for its success.

The "L"-shaped layout, an optimal window grid and ideal building depth guarantee maximum efficiency! The 14-story building offers an impressive panoramic view. The large-sized ribbon windows provide natural lighting throughout the building.

Three Building Sections

RWI4 is actually a building-ensemble. The twin towers rest on a socket which is surrounded by a hovering ribbon made of concrete components. This ribbon has the appearance of an over-sized sculpture and stands out from all sides.

The Socket

The socket is the structural unit that connects the two towers. Within it, all the amenities can be found. At the height of the first floor, it is encompassed by what looks like a ribbon made of hovering concrete components.

The Twins

Tower 1

This tower is RWI4’s gateway to Lorettostraße. Work and life happen here on a total of 14 floors.

Tower 2

This twin is identical to Tower 1. Both lead to the multifunctional socket building that provides the tenants with their daily needs.

rwi4 Hochhäuser


RWI4 consists of two towers. Each tower features two L-shaped wings. Each wing consists of two so-called "slices" or "discs" (German: Scheiben) that are arranged in a perpendicular angle to one another. The similarity to the five year older "Dreischeiben-Hochhaus" ("three-slices-high-rise") is unmissable.

Visual Appearance

Glass, aluminum and concrete! These three heterogenic materials are characteristic of RWI4’s visual appearance and complement each other perfectly. The sky reflects on the shining building envelope. At night, city life is mirrored upon it as the illuminated façade, in turn, adds a defining characteristic to the city’s skyline.

At the socket floor, a series of concrete components form a ribbon that gives RWI4 its unique character.


Architect and City Planner Professor Andreas Krys from Münster on RWI4, its effect on the city and why its origin can be traced to New York.

Professor Krys, we are standing in front of one ofthe most famous office properties in all of Düsseldorf, designed by the renowned architecture firm HPP from Düsseldorf. What are your feelings?

Krys: I am very impressed. On one hand, RWI4 stands in the middle of a compartmentalized and evolved district and on the other it is visible from almost all over the city.

Indeed. It almost appears as a giant amongst dwarves. Do you think it doesn’t fit here?

Krys: Yes, it does. I like the way RWI4 deliberately fits within the district. Just take a look at how this big building on Lorettostraße aligns with the smaller scaled proportions of neighboring buildings by presenting itself in a rather open manner with its entrance area and glass façade.

A lot of people wonder why there are two towers. As an architect, what do you think?

Krys: I think the builder and architect had the explicit wish to create two identical houses – twins, that is. Within the double existence lies the strength of the design. It is also an allusion to patterns that are deeply rooted in our thinking: day and night, good and evil, animus and anima. This concept really unfolds its effects!

Would you label this kind of architecture as modern?

Yes, I would. And in the best of senses, too.You see, the term “modern“ dates back to a seventy year old tradition and refers to virtually all architectural themes, for instance "living". High-rise, as an architectural theme, marks the very birth of modernity.

What do you mean by that? Are you thinking of New York?

Krys: Exactly! The German architect Mies van der Rohe has inspired generations of architects with designs like Seagram Building. I was no exception to that.

What exactly is it that impressed you so much?

Krys: Mies van der Rohe erected a high-rise for his client which to this day remains unparalleled in terms of elegance and simplicity. RWI4 clearly falls into line with this principle. Its extravagant elegance is proof of it. A design is either elegant and mundane or it isn’t.

Thankyou, Professor Krys.
