GG Real Estate has proved itself as an Amsterdam developer of highly sustainable residential buildings. The company is determined to keep on pushing for innovative sustainable solutions within its current and future residential development projects. During the past three years, GG Real Estate developed the Amsterdam residential building Juf Nienke, which has become the most circular residential development of apartments in The Netherlands with a GPR-score of 9,5 out of 10. This score reflects the ultimate performance on energy (-saving and -generation), materials (re-use, and re-usable), water (-collection and -use), health (sound, air, temperature), biodiversity, quality (functional and technical), social safety and degree of future-proofness (flexibility in use and function). The valuable lessons learned from this development gives GG Real Estate a head start in its current and future sustainable residential developments.
