The development of continuously lucrative real estate by a combination of the factors:
location – project ideas – capital – timing

QUEST has the access to the market, the resources and the expertise to develop real estate to the next level or from scratch. In the selection of the locations, QUEST is focussing in the field of office premises on urban ares (City and district locations) in Hamburg and Berlin as well on good central locations (prime locations) of German urban centers in the area of retail developments. Due to longterm connections and the good relationship with the tenants, new project ideas evolve even before the acquisition of real property.

Investment strategy
The aim is the creation of core real estate. Investments are only made in very good locations. There, the quality of the object is constantly improved.

The creation of values through:

  • Development of projects
  • Refurbishment and repositioning
  • Improvement of the rental and revenue situation


QUEST Development runs the project development business and currently has invested more than 1.6 billion euros in almost 30 projects spanning an area of over 217,000 m2. Preference is given to properties with a special flair and a unique selling point. The company offers a wide range of services, from project acquisition, due diligence and financing to planning, obtaining development rights, technical management and marketing for letting and sales.

A team of 40 experienced employees develops and manages high-quality real estate projects. The project development division also plans large properties as joint ventures with renowned institutional investors. The aim is to increase the value of properties with unique and innovative ideas and to actively participate in modern urban planning.



At QUEST Funds GmbH, founded in 2019, a team of 20 people is in charge of the fund and investment business as well as the asset management of the real estate company. The company makes individual investments in cooperation with institutional investors such as insurance companies, pension funds, foundations and family offices.


Property management

In 2021, QUEST Investment Partners acquired a majority stake in Albrecht Gebrüder & Co., a property manager founded in 1987 and based in Hamburg and Berlin. As a result, we are expanding further and entering a third business area in addition to project development and the fund business.
