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

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.
