Successful together
since 1955
Since its foundation in 1955, the weisenburger Group can look back on seven decades of successful company history. A regional construction company in Rastatt has developed into a leading full-service provider in the construction and property sector with more than 650 employees today and a total annual output of over €500 million. Over 3,000 new units are built every year - from residential buildings and terraced houses to care facilities, hotels and office and commercial space.
Tradition
meets the future
weisenburger bau stands for decades of expertise and efficiency in building construction. The broad portfolio in residential, commercial and social housing construction forms the foundation of today's strong performance. Continuous further development of production processes and the early introduction of innovative technologies are key drivers of the company's vision: to enable affordable construction for all.
With weisenburger projekt, the Group offers comprehensive project development and property development services - from planning and land acquisition to realisation and marketing. weisenburger invest completes the value chain as an independent asset manager and develops customised investment solutions for institutional investors, international capital providers and family offices. The focus is on project development joint ventures, strategic portfolio development and the revitalisation of existing properties.
On the occasion of its 70th anniversary, weisenburger looks back on an eventful history and consistently looks to the future: innovative, future-orientated and affordable construction and living remain the goal. With its subsidiary sanierungsprofi, which specialises in complete refurbishments across all trades and energy-efficient modernisation, the group is strengthening its portfolio and providing new impetus in the area of existing properties.
The weisenburger Group is also continuously expanding its international presence: In Romania, weisenburger real estate SR manages the sales process for current and completed projects. In Poland, weisenburger development sp. z o.o. is represented with several successful projects in the Warsaw region.

A success story
weisenburger's history is characterised by constant growth, innovative strength and the courage to break new ground. As early as the 1960s, the company was one of the first providers to focus on turnkey construction and took on a pioneering role in the industry at an early stage. Numerous milestones followed in the decades that followed: the founding of its own property development companies, the integration of new trades, expansion into other regions and abroad as well as the introduction of innovative construction methods such as lean construction and digital applications.
