Affordable housing: STRABAG launches TETRIQX – serial construction
solutions starting from € 1,950/m²

• Construction costs from € 1,950/m²*
• At least four months shorter construction time compared to
conventional methods
• Up to 50% reduction in CO₂ emissions versus traditional construction

STRABAG has unveiled a new, serially producible residential construction
product that tackles several of Austria’s housing market challenges at
once: rising construction costs, a shortage of affordable housing, lengthy
build times and the need for sustainable building methods.

TETRIQX is a modular building system with a high degree of prefabrication.
Functioning like a building kit, it offers three fully planned residential
building types for different construction categories. All three can be
added on top of existing residential buildings up to seven storeys high
and feature optimised layouts ranging from approximately 44 m² to around
88 m². 

New solutions to the housing crisis
At a time when conventional construction and funding models are reaching
their limits, TETRIQX opens up new perspectives for urban housing
development – high quality, efficient, sustainable and, above all,
affordable. Thanks to its modular prefabrication, construction times are
reduced by up to four months compared to traditional methods. In some
cases, overall project timelines can even be cut in half. This not only
makes investment in new housing more attractive again but also reduces
disruption to neighbours from construction sites.

For Markus Engerth, Member of the Management Board of STRABAG AG Austria,
TETRIQX is more than just another construction product: “Affordable
housing is possible – but not with yesterday’s solutions. We have to build
faster, more sustainably and more standardised, without compromising on
quality. With TETRIQX, we deliver a solution that enables prices from €
1,950 per square metre for high-quality homes. That’s a genuine remedy for
the looming housing crisis.”

Innovation for sustainable construction
TETRIQX also sets new benchmarks for sustainability. With concrete core
activation, buildings can be heated efficiently in winter and kept
pleasantly cool in summer – at no additional construction cost. This
reduces heating and cooling energy requirements during operation by at
least 22%. In addition, efficient serial production using sustainable
materials cuts CO₂ emissions over the building’s entire life cycle by up
to 50%.

The first projects are scheduled to start next year.

*Price as of 1 January 2025, excluding planning and parking garage.
