Siewertsz Beleggingen develops residential real estate complexes in collaboration with institutional investors. We also conduct high-end renovations of residential and retail real estate. We do so in close collaboration with selected specialised contractors and architects. These houses and stores are fully overhauled with a meticulous eye to detail and subsequently offered for sale or lease through various accredited NVM real estate agents. Siewertsz Beleggingen works in collaboration with various co-investors and co-developers.
