Microlight Sculpture

Microlight Sculpture

The Erich Kaestner House of Literature, Dresden

The octagonal prism of the micro light sculpture, a homage to the Danish poet Inger Christensen, symbolizes with its geometry the physical elements of nature: sky, earth, fire, water, wind, thunder, lake and mountain. Nuances of light and shadow, space and surface can be experienced. The multi-layered play with perspectives and the dissolution of boundaries sensitizes the viewer to an intense optical experience. The visual labyrinth of inner and outer world points to relations between micro and macro, to the polarity of unknowability and readability of art and the world. In the daylight, the object can be experienced multidimensionally in dialogue with the movement of the sun as a cast shadow, in the darkness with artificial light from the core: inside and outside, below and above are interchanged.

MDR – Bridge, Leipzig

Pedestrian and Bicycle Bridge, MDR site, Leipzig

Lighting concept for the new pedestrian bridge

The new pedestrian and bicycle bridge (KHP Leipzig / Kolb Ripke Architekten), with its restrained and elegant bridge construction, assumes an important connecting function in the development of the MDR area in Leipzig. With its simple, linear view reduced to the minimum, the bridge is integrated into the landscape in a restrained manner. This intention is supported by the discreet, calming, high-quality lighting with warm white light (color temperature 3000K).

On The Road in the Light 2020, Potsdam

Architectural lighting concept for Potsdam’s center “Soundless Music”

The images show excerpts from Ruairí O’Brien’s lighting composition for Potsdam On The Road In The Light 2020, including the Brandenburg State Parliament, St. Nicholas Church and the Potsdam Film Museum. “With an authentic concept, high-quality technology and a selective choice, you can achieve more in lighting design. To create poetic and exciting lighting atmospheres, you have to understand how time, space, materials, darkness and light can be brought together and how they can be set against each other.” Ruairí O’Brien

City Warehouse Jena with Hologram Façade

City Warehouse Jena with Hologram Façade


After years of vacancy, the historic post-and-beam building of the city warehouse in Jena was brought back to life through the step-by-step implementation of the city warehouse concept developed by Ruairí O’Brien. The identity-creating overall concept for the revitalization of the monument connects inside and outside and past, present and future and creates an attractive upgrade of the inner-city living space.

Hologram facade Jena

According to O’Brien’s design, the city warehouse at Jena’s market square presents itself with a hologram façade and new roof, integrated into the existing market ensemble in terms of urban development. After years of vacancy, the historic post-and-beam building was brought back to life through the gradual implementation of the city warehouse concept developed by Ruairí O’Brien. The identity-creating overall concept for the revitalization of the monument links the past, present and future of the city and creates an attractive upgrade of the inner-city living space. The hologram conveys a holistic message that breaks new ground in the living preservation of monuments.

Hologram façade- Built urban identity

The hologram façade embodies the essence of the city of Jena, it is a tribute to its spiritual and economic identity. The façade as an independent aluminum-steel-glass construction placed in front of the listed building depicting a spatial expression of the city storage concept. The identity-creating “eye” of the building highlights the historically significant structure inside with translucent to transparent effect and protects the valuable center of the monument. The hologram façade of the city warehouse forms a tailor-made connection between contemporary architecture and the historic structure.

Light Sculpture for the Schwerin Market Place

Light Sculpture for the Schwerin Market Place

micro light sculpture 01

The micro light sculpture in Schwerin was the first in a series of light sculptures that architect and artist Ruairí O’ Brien purposefully developed using simple means, simple materials and simple construction as a tribute to the art of architecture, to the effect of light on people, space and time.

Light sculpture for the Schwerin market place, consisting of 3 equal, variably combinable modular parts, which in the present composition form a cube space and a focal point to the light theme with quiet action character. During the day it takes the function of a shadow caster, in the evening that of a light machine. In a subtle way, it reflects the chronology of the daily routine and the dramaturgy of life, ergonomically illustrating the relationship between micro and macro scale.

Modern Working Worlds – Lighting Concept for Office / Office Area

Modern Working Environments – Lighting Concept for Office / Office Area IT-Department

Office areas, meeting rooms

In accordance with our client’s high demands for an attractive working environment for the company’s employees, our lighting concept combines great functionality with attractive design. For each area of the open-plan office floor, an individual lighting concept was developed, which optimally supports the individual use of the rooms, from computer workstations, meeting rooms, informal areas, to individual offices.

The lighting of the entire company area changes depending on the amount of daylight, i.e. the luminous flux of the luminaires is coupled with the daylight through sensors and the color temperature transforms depending on the time of day (Human Centric Lighting).

The visualization of the planning shows a light scene in darkness. Light lines indicate the course of the corridor and elegantly “floating” office luminaires mark the individual work groups. With their indirect light and the large-area illumination of the ceiling, the room is visually widened and the biological lighting effect is supported.

Slaughterhouse Five

Slaughterhouse-Five, Messe Dresden

Memorial wall and information light sculpture

The artistically designed information light sculpture / memorial wall “Slaughterhouse Five” is visited annually by tourists from all over the world.
In the basement of the former slaughterhouse, the American author Kurt Vonnegut – like his protagonist Billy Pilgrim – survived the Allied forces bombing of Dresden on February 13, 1945 as a prisoner of war. The multimedia literary sculpture allows the viewer to experience the metamorphosis of the city of Dresden.
Through the artful superimposition of drawings, paintings, photographs, and city map excerpts, embedded in a complex grid of wood and Plexiglas, various temporal levels of the city’s history and at the same time the collage-like nature of the novel become visible. Lit from behind, the structure appears sculptural incorporating light and shadow as part of a larger picture.

Lighting Concept Bahnhofstrasse Lichtenrade, Berlin

Lighting Concept Bahnhofstraße Lichtenrade, Berlin

Lighting masterplan for the active center, the district center, the shopping street

The planning of the public lighting for the traffic areas (street) and secondary areas (pedestrian and recreational areas) is an essential part of our lighting concept for Bahnhofstraße Lichtenrade. The street and sidewalk lighting is coordinated with the superordinate lighting concept of the city of Berlin.

In addition to the use of light as a design tool to improve the appearance of public spaces and to increase the quality of stay in Bahnhofstraße, the lighting always serves first to ensure traffic safety. By providing uniform illuminance, emphasizing conflict zones and avoiding disturbing light (glare), safety for road users is increased and the quality of stay in the urban space is supported. The subspaces (microspaces) defined in the lighting master plan can optimally fulfill their function of structuring the public space, increasing attraction and dwell time even in the dark half of the day or year. Consideration was also given to the future redesign of the commercial street and the lowest possible maintenance and energy costs while optimally fulfilling the lighting task.

The Erich Kaestner House of Literature, Conversion of Museum Rooms

The Erich Kaestner House for Literature, Dresden

Conversion of the museum room

The structural changes made it possible to maintain the distance regulations for visitors to Dresden’s popular literature museum required during the Corona pandemic, so that museum operations could be safeguarded in times of pandemic.

The previously highly structured premises of the Erich Kaestner Museum, consisting of a checkroom, hallway and exhibition room, were converted into a spacious museum room using our opening room concept. Entrance and exit of the museum were separated from each other in the new concept.

In addition, the museum rooms were redesigned according to Ruairí O’Brien’s color concept.

Psychotherapy Institute for Children and Adolescents

German Society for Behavior Therapy in Saxony, Germany. Institute for Children and Adolescents in Dresden (2021-2022)

The institute’s new location is a newly renovated, landmarked villa in Dresden-Blasewitz, Germany.

Light, color, and material choices play an important role in creating the right atmosphere for all age groups and the various scenarios of discussions, presentations, and meetings that take place at the institute. As those responsible for the interior design, it was of utmost importance for us to balance the heaviness of the old, charming building with bright, friendly, appealing and even thought-provoking interiors. The choice and use of different colors, lighting fixtures, mirrors, materials and decorative elements tell stories that give the reception, offices and therapy rooms their own identity. The impressive staircase is celebrated as a special space that connects the floors. The dark basement needed special attention so that it could be used for seminars and educational purposes. At the Psychotherapeutic Institute in Dresden, child and adolescent psychotherapists and psychological psychotherapists are trained with a strong practical orientation. In addition, outpatient psychotherapeutic treatments are offered in the institute’s outpatient clinic.

Requirements for the current use are as follows:

  • Work office / administration
  • Treatment of patients / therapy rooms
  • Training / seminar rooms
  • Flexible uses – adaptation / change between seminar and group therapy uses
