Master Builders. Two Generations of Experience.
Postu Bau is a Vienna-based construction company specialising in new construction and renovation - from residential and commercial new builds to full-scope renovation and the restoration of historically significant buildings.
Director Iurie Postu has over 20 years in construction management, leading complex projects across Vienna and Austria from planning through to handover. His experience spans every scale of residential and commercial construction - from single-family homes to multi-storey apartment buildings and commercial fit-outs.
Master Builder Dipl.-Ing. Gerhard Notthaft contributes more than 30 years of engineering experience, covering structural design, material specification, and site execution. His expertise in historical renovation and Denkmalschutz projects is a cornerstone of the company's capability in heritage work.
Together, they lead a site team that has delivered over 50 projects across Vienna and Austria. We work across Austria. For exceptional projects, throughout Europe.



How we work
Single point of responsibility
We manage every stage of a project from our own team - no handoffs, no coordination gaps. One contract, one contact, full accountability.
Authentic materials
For renovation and restoration, we specify and source the correct materials for each building type - authentic lime plasters, period mortars, and mineral finishes for historic structures.
Baumeister expertise
Both directors hold the Baumeister licence - Austria's highest construction qualification. Every project is led by a licenced professional with full legal and technical responsibility.
Authority coordination
We handle all permit submissions and authority liaison - including Bundesdenkmalamt coordination for heritage-listed buildings - so projects move forward without delays.
The Team
Licensed master builders and experienced professionals - handling every project with care, from straightforward renovations to complex heritage restorations, across Vienna and all of Austria.
