On the Teglholmen island in Sydhavnen (the Southern Harbour), Vandkunsten Architects have designed 120 new apartments (both owner-occupied and rented units). The buildings rest on piles in the harbour basins. Under the piles there are tables where residents can gut fish they have caught in the harbour. I belive that originally the piers were ment for houseboats, but i don't know what happend to that idea!
