Project Description

This glass roof structure in Paris is a striking example of how historical use of space can be harmonised with contemporary requirements. In the heart of the French capital, DBG Classics realised a new conservatory-style glass roof structure above an existing building where a greenhouse had previously been located.

The original glass roof structure had disappeared over time, yet the conservatory concept had always been part of the building. Rather than abandoning this element altogether, the decision was made to recreate the glass roof structure.

Where the greenhouse was once used to protect plants and vegetables, it now shelters an office space flooded with natural light.

The result is a contemporary glass roof structure that translates the original idea into an architectural solution that meets today’s standards.

From historic greenhouse to contemporary roof structure

The strength of this project lies in continuity. As a greenhouse previously existed on this site, the new glass roof structure naturally reconnects with that original use, while introducing a change of use for the space below.

Beneath the glass roof lies an office environment that benefits from an open and pleasant working atmosphere thanks to the transparency and height of the structure. Daylight penetrates deep into the building, enhancing both functionality and visual comfort.

This approach demonstrates how a glass roof structure can act as a bridge between past and present without resorting to nostalgia or imitation.

Other commercial applications can be viewed here:

Curved tempered glass as a source of light and elegance

For this project, curved tempered glass was deliberately chosen, a material that is both technically and aesthetically demanding. Each glass panel was custom-made to fit perfectly within the curvature of the metal structure.

The use of tempered glass guarantees safety, durability and stability, all essential qualities for a glass roof structure in an urban setting such as Paris. At the same time, the curved form creates soft lines and an even distribution of natural light beneath the roof.

Thanks to this choice, the glass roof structure remains visually light despite its scale and presence.

Ventilation and comfort through automatic window openers

To ensure a comfortable indoor climate, the glass roof structure was equipped with automatic mechanical window openers. These provide natural ventilation without the need for complex or visible technical systems.

The window openers respond to temperature changes and automatically release warm air.

This keeps the space beneath the glass roof comfortable, even on sunny days, without compromising the calm and refined design.

This form of passive ventilation fits perfectly within the conservatory concept and reflects the philosophy of DBG Classics: integrating technical solutions that support the design rather than dominate it.

A green extension to the shared office space

Above the existing flat roof, the glass roof structure creates a sheltered area that naturally invites a green interpretation.

Instead of technical installations, this level could be envisioned as a green extension of the office environment with potted plants and small vegetable-growing elements.

This space can function as an informal meeting area where colleagues care for plants together, grow herbs or tomatoes, and take a moment to unwind during the working day.

The roof level could gain a human and social dimension, fully aligned with the project’s philosophy.

The glass roof structure protects this potential green zone from wind and weather while preserving its open character.

Wrought iron and glass in a refined execution

The supporting structure of the glass roof structure was executed in wrought iron with a traditional finish. Slender profiles, carefully detailed connections and structural arches give the construction a refined appearance.

In a dense Parisian urban environment, such attention to detail is essential. The glass roof structure had to integrate harmoniously with surrounding façades, railings and rooflines, without visual dominance.

This project demonstrates how wrought iron and glass remain a timeless combination in contemporary architecture.

Glass roof structure installed by DBG Classics in Paris

The complete installation of this glass roof structure in Paris was carried out by the DBG Classics team. Although our projects are generally located in Belgium, we are happy to collaborate with clients just across the border.

In this case, the nature of the glass roof structure, its technical complexity and the proximity of the location made it possible to manage the installation in its entirety, with close attention to detail and on-site coordination.

This remains an exception to DBG Classics’ general guideline of providing installation services exclusively within Belgium. International clients can however order a self-build conservatory kit and have it installed by a local contractor.

This project nevertheless illustrates that DBG Classics can remain flexible depending on the project and its precise location.

Do you live just beyond the Belgian border? You are welcome to request an online quotation to see whether an exception may be possible for your project.

A glass roof structure as a future legacy

This project proves that a glass roof structure can be far more than a purely functional element. It reinterprets a historic greenhouse, gives it a new purpose, and adds light and quality to the building.

By combining curved tempered glass, refined wrought iron and natural ventilation, an architectural solution emerges that is both durable and timeless, allowing the building to breathe once again within its urban context.

Interested in a bespoke glass roof structure?

Are you considering a glass roof structure for an office, residential or urban project? Are you looking for a solution in curved glass, tempered glass or refined wrought iron?

DBG Classics designs and realises bespoke glass roof structures, fully tailored to the architecture, use and context of each building.

From contemporary interpretations of existing greenhouses to new roof structures in wrought iron and glass, every project starts with close consultation, in-house design, and craftsmanship executed on site.

While our projects are mainly located in Belgium, we assess on a case-by-case basis how we can support clients beyond national borders, either:

  • through installation by DBG Classics (in Belgium or just across the border), or
  • via a self-build kit that can be shipped worldwide.
