Social responsibility

We look beyond our own noses

We are keen to assume social responsibility. We convinced that we can have a positive influence on communities and people. In principle, it is always about us people first. The focal point of our activities and efforts is therefore each one of us as an individual. Our concern is about the employees in our company and about the people around us. Our concern is about society.

We are also constantly seeking new challenges and was to set positive markers and, especially in this day and age, to improve things and help people.


Here is an overview of our activities in various fields:


We have more than 70 employees in the company group - with a rising trend - and also prefer to resort to insourcing instead of outsourcing as a core business philosophy.


We attach great value to the compatibility of job and family. Therefore, for example, we offer flexible working hours and parental benefit plus and further elements to promote employees' satisfaction.

Young talent promotion

We promote the next generation of professionals in the form of internships and work student positions which we regularly offer.

Children's days

We organize children's days for our employees' children. This is one way we boost social cooperation among colleagues.

Local craft trades

We continually support local craft firms with commissions for our portfolio properties.

New living space

Since our company was founded, we have revitalized or erected 3,000 apartments in Berlin alone. We are also currently working on various new-build projects.


We refurbish dilapidated and uninhabitable properties, so that they can be put back on the housing market and people can find a new home.

No luxury refurbishments

We do not carry out luxury refurbishments, only to hike rents sharply and get rid of existing tenants. All our refurbishments serve to maintain the building structure and inhabitability.

Urban development

We play a part in urban development by refurbishing and embellishing facades, back yards and open spaces.


The Jakob Mähren Foundation helps people in need. A multi-facetted engagement in children's homes and neighborhood associations through to school projects with a focus on Berlin.
