   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.
