Elithis is today an integrated group, both a consulting engineer and a designer and builder of buildings with exceptional energy and environmental performances. Its scope is embodied in the group’s structure, which brings together its businesses to improve living comfort and the sustainable city.

“Elithis is first of all a team of engineers gathered in our subsidiary company ” Elithis Solutions ” dedicated to the energy efficiency and specialized in the building engineering and consulting. We transform this grey matter within our second subsidiary “Elithis Immobilier” to imagine real estate products with outstanding performances. And this in order to answer to our group’s vocation, which is to bring concrete solutions to the great stakes of the 21st century such as the climatic disturbance.

FOR WHICH PARTNERSHIP?

A same vision and a same attachment to propose an innovative way for the residential and mixed real estate of tomorrow, respectful of the environment and concerned with the comfort and the purchasing power: this is what links the Elithis group and Catella Residential Investment Management.

By joining forces, the two partners are able to offer unprecedented European residential and mixed-use investment opportunities, both in terms of scale and in terms of their sustainability and social responsibility objectives in this sector.

This partnership, unique in the real estate ecosystem has taken the form since 2019 of a €2bn investment program, dedicated to the construction of 100 “positive energy” residential towers in various European cities by 2030.

WHAT BENEFITS FOR OUR PROJECTS, USERS AND CITIES?

PERPETUATES AND SECURES THE PROJECT

Our investor partner Catella Residential Investment Management confirms its interest in the project as soon as it is feasible. This investment allows us to perpetuate and secure the financial commitments made. This long-term investment ensures the expected quality and durability of the building.

A NEW POSITIVE ENERGY OFFER THAT ENHANCES THE PURCHASING POWER OF THE LOCAL HOUSING MARKET

Catella Residential Investment Management will exploit the future real estate asset by marketing a free rental offer of accessible housing. This new offer integrates the territory’s residential path with new attributes: positive energy and the revaluation of purchasing power.

SUSTAINABLY COMMITTED TO THE TERRITORY

Catella invests in the territory and ensures the rental management of the property. Its durability and maintenance are therefore guaranteed thanks to this long-term involvement.
