Two titles in one cover. On page 56-112 there's the English version of the book: 'A viable real estate economy with disruption and blockchain. Does real estate still have the value that it had, or is the valuation of real estate going to change due to surprising products and services, innovative business models, other market strategies, innovative ways of organizing and managing in (real estate) markets? Innovation revolves around good facilities in an attractive and stimulating environment. Take disruptive real estate. The driving forces behind these developments are new technology, manoeuvrability, a different way of organization and management. These forces greatly influence the valuation of real estate.
