Historic Building Gets New Balconies

Back in the 19th century, this yellow building on Bådmandsstræde in Copenhagen was constructed with the purpose of housing widows of the state's naval officers. Today, the building contains beautiful, bright apartments. Apartments that, in 2021, needed, among other things, new balconies.

Altana A/S delivered 19 balconies and 2 stairwells for the project - all in steel, with balcony ceilings in GRC. We produced a total of just over 50m2 of balcony ceilings for the project's 19 balconies, with a thickness of 12 mm, with recessed holes and corresponding plugs in the same material. The elements were made with a one-sided slope of 4 mm.


Altana A/S states:

"The project on Bådsmandsstræde in Copenhagen consists of 19 balconies and 2 stairwells, including window doors, for a historic building from the 19th century.

Here, the balconies are in steel, but the client and advisor had specific requirements that the balcony ceilings should be made of GRC. GRC balcony ceilings from BB fiberbeton are a natural choice for us when there is a particular desire for the materiality and surface texture of steel balconies, as the concrete surface provides a beautiful and balanced expression in harmony with the balcony's other smooth metal surfaces."

Durable, lightweight, formable

GRC cladding

Through design and manufacturing we help architects, entrepreneurs, and builders create unique, durable, and sustainable facades. Whether you are starting construction on a new build or embarking on a renovation project, GRC is suitable for both.

Glassfibre reinforced concrete (GRC or GFRC) is incredibly versatile and grants you an architectural design freedom with almost endless possibilities. With the formability of GRC you can achieve any geometry and with a surface designed for your specific project. GRC is a lightweight material and our cladding elements are typically only 12 mm. Thus, making it easier to work with and transport whilst also easing the load on buildings.

GRC is an excellent facade material if durability and sustainability is of great concern and importance. GRC is durable for more than 100 years without any technical maintenance and it does not dent, rot, corrode, nor burn (class A material). With a sustainable material and an environmentally friendly production without toxic materials, GRC elements from BB fiberbeton are ideal for environmental certifications, such as LEED, DGNB, and BREEAM.

GRC is made of white cement and fine aggregates and reinforced with glassfibre. Elements are produced using a special spray-technique that allows for a low water/cement-ratio, a low thickness, and a high strength.
