In this way we offer our partners and clients short communication routes with their points of contact and the synergy of a strong group.

Constant demand for our products and services confirms our practice of always guaranteeing the optimum quality and speed of implementation.

For us, sustainability is not a burden but a principle we have lived by for 50 years. As one of the largest emitters of global greenhouse gases, the entire real estate industry is obliged to live up to its responsibility for future generations. This can only be achieved by specifically promoting both the energy-efficient refurbishment of existing buildings and the socially and ecologically sustainable development of future-proof properties. We proactively develop all aspects of sustainability with a unit set up specifically for this purpose.

Environmental protection certainly plays a decisive role in connection with ESG considerations. The central task for us with regard to new development as well as the refurbishment of existing buildings is to consider the property in its entire life cycle in order to take into account not only the energy demand with regard to construction, maintenance and deconstruction, but also the demand during operation. We are very proud to have already taken on a pioneering role with our landmark projects KII in Düsseldorf and the Hafenpark Quartier in Frankfurt.




1. climate change
Use of renewable energies in operations and construction. Photovoltaics on the roof and façade surfaces depending on the conditions of the building structure for solar and geothermal energy. Intelligent lighting control and LED use, recuperation of lifts, promotion of e-mobility.

2. adaptation to climate change
Transparency on site risks and their management.

3. water and marine resources
Storage and use of grey water (faecal-free, only slightly polluted waste water).

4. transition to a circular economy
Pursuing the C2C approach - Cradle to Cradle is an approach where products are designed from the beginning to be reused or composted later. Use of the onion principle, where individual building components can be renewed separately without having to demolish the entire building. Use of CO2-reduced concrete, aluminium and green steel (CO2-reduced steel produced with hydrogen instead of carbon). 

5. pollution prevention and control
Use of low/pollutant-free materials, avoidance of heavy metals and lead-containing materials.

6. protection and restoration of biodiversity and ecosystems.
Reduction of land sealing, reforestation and renaturation of replacement areas, creation of green facades and roof landscapes.


The health and well-being of our employees is a high priority for us. The compatibility of family and career is made possible through flexible working hours and home office.

For many years, the B&L Group has been active as a training company and supports young people in their entry into professional life.

As an equal opportunity employer, diversity in the workforce and the preferential recruitment of women with the same qualifications is supported.

In order to increase the health awareness of employees, the B&L Group also organises information events such as a health day.


In order to harmonise the company's values with the legal and social framework, the B&L Group has created an integrated, company-wide compliance code that is binding for employees, business partners and subcontractors. A guideline for sustainable management and the sensitive treatment of the environment has also been drawn up.




The B&L Group is a member of the ECORE (ESG Circle of Real Estate) initiative, which has set itself the task of creating transparency about sustainability in the real estate industry. For this purpose, a comprehensive scoring system was developed with the involvement of many well-known industry players.


In Frankfurt's Ostend district, the B&L Group is developing the Hafenpark Quartier, consisting of condominiums, hotels and offices. Both office complexes are already LEED Platinum pre-certified and consistently follow the cradle-to-cradle approach.


In the heart of Düsseldorf, the B&L Group built the high-street property "KII" together with the Centrum Group. The striking beech hedge that surrounds the building not only binds C02, but also acts as natural insulation. The project was subsequently not only awarded the highest DGNB Platinum certificate in its class to date, but also received the DGNB Diamond certification for its high design and architectural quality.


In addition to the development of new, innovative projects, our heart also beats for the sustainable preservation of listed buildings. In Weimar, we built a luxurious boutique hotel based on the remains of a listed façade from 1897, which carefully combines the old building fabric with modern architecture. We also participated in the renovation of the two historic harbour cranes at Hamburg's oldest remaining harbour basin - an industrial monument and landmark for the Holzhafen district.


The world of work is undergoing fundamental change. From flexibility in terms of work location and time to the way we communicate and collaborate within the office space and beyond. In our landmark project HPQ Offices, we will integrate all aspects of a future-proof office. This includes the division of the premises into meeting zones, optimal lighting and oxygen control, and even deliberately placed elements to promote physical and mental fitness.


For many years, the B&L Group has supported the "Haus Mignon e.V." association, which is dedicated to supporting children whose development is impaired due to premature birth, illness, disability or traumatic experiences in several facilities.
