“Mycelium is the network that a fungi has underground. This network connects all the fruit hats of the fungi that is spread out through the forest”

Our approach is based on the idea of the mycelium, the transformation from single office headquarters to a decentralized connected network of offices embedded in the future smart city while at the same time forming it. This approach is of today new for both investors and potential users why Mycelium offers a first mover advantage where the investor will be a pioneer in a completely new type of real estate investment. A major focus on real estate in the last years have been on smart buildings, the problem is that most conventional approaches views a smart building as a structure filled to the max with the latest technology. This presents a problem otherwise small in the real estate market, lifetime. The technology invested in a building today will be outdated within 5 - 10 years rendering the smart building unsmart. The focus on smart buildings therefore needs to shift, from an economic perspective, to something more sustainable throughout time by substituting most of classic office buildings. In our paper we calculated the estimated yield rates, the space and money savings and the agility advantage through a comparison of the traditional office and Mycelium. Furthermore we make an outlook on the implementation in the smart city.
