BESTAND BEYOND offers comprehensive solutions for the refurbishment and transformation of existing buildings.
Whether it’s building refurbishment, energy efficiency upgrades, fire safety or the removal of hazardous substances: we plan and carry out complex projects whilst the building remains in use – precisely, digitally and with a focus on energy efficiency, resource utilisation and cost-effectiveness.
Comprehensive refurbishment – digital and precise
Our services range from an analysis of the existing portfolio, through general planning and technical implementation, to operation. We therefore take the entire property lifecycle into account and regard the management of existing buildings as a strategic task. With our specialist experts, we provide advice from service phase 0 onwards on circular economy principles and funding opportunities, and take aspects of construction and subsequent operation into account at an early stage in the planning process. Furthermore, through Building Information Modelling (BIM) and LEAN methods, we create transparency, minimise interfaces and ensure quality. This results in solutions that are not only structurally sound but also function effectively in the long term.
Decarbonisation of the existing building stock – energy optimisation
The buildings sector plays a key role in achieving climate targets. That is why, when it comes to existing buildings, we focus specifically on decarbonisation and energy optimisation. ThroughBESTANDBEYOND, we carry out projects in which, depending on the initial situation, measures can be implemented to reduce energy consumption, cut emissions or optimise energy efficiency. In doing so, we draw on digital tools, building materials selected specifically for each project, and smart building technology.
Whether it’s a complete refurbishment, a change of use or an extension: we develop concepts tailored to the clients’ requirements and the users’ needs. BESTANDBEYOND stands for collaborative partnership, technical excellence and sustainable property solutions – for public, commercial and private clients.

Interview at Deutsche Bauzeitung
In the March 2026 issue of Deutsche Bauzeitung, you’ll learn how BESTAND BEYOND is setting new standards in the field of building renovation. Our expert Robert Rauch discusses the innovative approach of our product brand and how it will transform the building stock of tomorrow.
Leading by example: “Symposium anders! Bauen im Bestand”
The “Symposium anders! Bauen im Bestand” symposium focuses on the innovative renovation of the Z2.0 building in Stuttgart-Vaihingen. Ricarda Metelmann-Scholz and Rolf Becker from ZÜBLIN, along with Mariele Weiss from STRABAG, will present how circularity is implemented in construction practice. They emphasize the conscious use of existing building components and explain why “Circular construction is a choice” is more than just a slogan.
A new use for old stock?
Together with BESTAND BEYOND, we can make the transformation a success.
