Our vision

The real estate industry is under enormous pressure to act: In addition to global warming, social and socio-political realities require quick but absolutely sustainable solutions, especially in residential construction. Gröner Group AG is facing up to these challenges and is consistently pushing ahead with Christoph Gröner’s vision of the digital reorganization of the construction and real estate industry, incorporating ecological and technological innovations.

Gröner Group wants to change the market: With ecobuilding, our company is focusing on a different kind of construction and a new kind of building – ecological, economical and digital. ecobuildings combine everything in one: affordable living space, high-quality architecture, diverse, livable neighborhoods, economic efficiency and sustainability in operation – all the way to CO₂ neutrality.

With its subsidiary CG Elementum AG, Gröner Group has an in-house service provider for digital and sustainable construction that offers the entire range of services for internal and external project developments in the areas of new construction, old building/monument renovation and conversion.

As an internal service provider, CG Elementum is our company group’s flagship entity. It follows principles of sustainability and is committed to forging ahead with the digitalisation of planning and construction processes that harness BIM and its sister field of prefabrication to create both affordable and unique architecture with the end goal of achieving a carbon neutral footprint. For this, all green technology concepts are checked to see if they can be applied to new construction projects. In addition, CG Elementum also draws on many years of experience and outstanding expertise in urban development as well as in conversions, revitalisation and the renovation of old and listed buildings.

CG Elementum services help shape the development of new construction projects at CG Property, with a focus on digital planning and construction. Meanwhile, at CG Capital, CG Elementum supports project developments in the areas of renovation, revitalisation and conversion. Alongside its involvement in the company’s own developments, CG Elementum also acts on behalf of external third parties.

We relish a challenge and offer outstanding solutions

The building industry is up against some fundamental challenges, including a scarcity of affordable living space, the acute shortage of skilled labour, innovation gridlock in planning and construction, and the need to reduce carbon emissions in order to protect the climate. We offer outstanding solutions and embrace our social responsibility.

1. Environmental/social responsibility

Reduction in carbon emissions
in the interests of climate protection

Construction debris
and recycling

Use of healthy construction materials
and resources in Europe

Insufficient provision
of affordable living space

2. Resources/productivity/innovation

Shortage of young talent;
movement of skilled labour and early retirement

Low productivity

Low technical integration
of planning and construction

Complex traditional business models
with high financing needs

What motivates us

We believe a radical shift is needed – from a traditional resource-consuming approach to a sustainable strategy for resource-conserving project developments that align economic, environmental and social interests.

Our approach

By establishing a digital end-to-end process chain, we demonstrate our commitment to a design-to-construction approach. We also focus on the revitalisation and conversion of existing building stock, combined with technological improvements and environmental innovation.
