CG Elementum – flagship of the Gröner Group

Established in 2020 as a subsidiary of the Gröner Group and internal service provider to it, CG Elementum exemplifies property developments built for the future. We follow principles of sustainability, forging ahead with digital design and construction to create affordable but also unique and high-quality architecture. What’s more, we preserve value by giving disused industrial buildings a fresh lease of life and putting them to new use. We always look for ways to apply our range of green technology concepts, especially in our new construction projects.

Our principles

CG Elementum’s history started more than 25 years ago when Christoph Gröner established the CG Guppe. Over time, the group began to specialise in project development for rental property. Building on this, CG Elementum – a subsidiary of the Gröner Group – now unites all processes involved in the property lifecycle under one umbrella, from design and development to construction, lettings and management.

In everything we create, we aim for a standard of holistic sustainability that always includes both ecological and economic considerations. On the one hand, we pay very close attention to process digitalisation. This combines BIM and the use of prefabricated components to make developing new buildings more efficient in terms of both time and money. The result is affordable housing and living spaces that harness green technology to optimise carbon emissions. This brings us closer to achieving a carbon neutral footprint.

On the other hand, our longstanding expertise in conservation-based renovation and conversion feeds into our specialisation – preserving values instead of building on greenfield sites. By developing properties in a manner that conserves resources, we revitalise old industrial sites and buildings to create new housing and living spaces. As part of this, structures that merit preservation undergo extensive renovation and are put to new use. Buildings that are not worth maintaining are demolished and recycled as demolition debris. The space cleared is redeveloped to allow new and vibrant city centre districts to spring up. For an approach that is sustainable in so many ways.
