Evolver, Zermatt, Switzerland, by Alice Studio/EPFL. There’s more than one way to enter this temporary structure in the Swiss Alps: visitors can sneak in through the apertures in the walls to experience what its architects described as ‘a destination and an activity’. It is one of the fascinating buildings collected in Wood, by William Hall and Richard Mabey, published by Phaidon. (Photo by Joel Tettamanti/Alice Studio EPF/The Guardian)
