The copper tubes that branch across the walls and ceiling of this Amsterdam barber shop by Ard Hoksbergen carry both water and electricity (though not in the same pipes).
Some channel water to the sinks but others culminate in light bulbs or hooks against a backdrop of white tiles, plywood and concrete.
Hoksbergen compares the pipes to "a giant cobweb" and says natural materials were chosen to create "a raw but warm atmosphere."
Called Barber Amsterdam, the shaving salon is housed in a 19th-century shop in the city centre.

Hoksbergen was one of five graduates awarded the Dutch Archiprix for their student work in June.
