A neighbourhood that offers more than just housing
In the immediate vicinity of Vienna Central Station, a new part of the city is taking shape with the “Neues Landgut” development area. The B.R.I.O. housing project is part of this neighbourhood and combines affordable housing with a clear commitment to sustainability, social diversity and quality of life.
175 subsidised flats offer space for a variety of lifestyles – from compact units to family-friendly layouts and shared accommodation. The concept is complemented by communal spaces such as co-working areas, playrooms and communal zones, which encourage social interaction in everyday life.
The result is a housing project that goes beyond mere functionality and is geared towards long-term usability and social quality.

Hybrid timber construction for efficient building
A robust hybrid timber construction method was chosen for the project, which specifically combines the advantages of different materials.
The load-bearing structure is based on a system of glulam columns, supplemented by slabs made of recycled concrete with reduced thickness. This construction method enables an efficient use of materials whilst significantly reducing CO2 emissions compared to conventional reinforced concrete solutions.
In total, over 1,000 glulam columns and more than 9,000 m² of prefabricated external wall elements with a thermally treated pine façade were used.
Prefabrication as the key to the project’s success
A key factor in the success of B.R.I.O. was the high degree of prefabrication.
The wall elements were fully prefabricated at our plant in Ober Grafendorf – including window installation and sun protection. This allowed for optimal control of quality, precision and workflow.
On site, this enabled rapid and structured installation, even under the typical conditions of an urban environment with limited space and complex logistics.
Close coordination between planning, production and assembly was crucial for the smooth running of the project.
Sustainability throughout the entire life cycle
B.R.I.O. considers sustainability beyond the construction phase.
The combination of timber and recycled concrete not only reduces CO2 emissions but also enables the resource-efficient use of materials. Green facades and roof surfaces help improve the microclimate and provide protection against overheating in summer.
A low-tech heating and cooling system also ensures energy-efficient operation.
The result is a building that combines ecological and economic aspects – from construction through to use and beyond.
A project that demonstrates what is possible
B.R.I.O. clearly demonstrates the potential of multi-storey timber construction.
Through precise prefabrication, well-thought-out design and close collaboration between all parties involved, a project has been realised that creates affordable housing whilst meeting high standards of quality, sustainability and architecture.
A residential building that not only creates space, but also a future.
