Oh, to live in New Zealand with all the elves and dwarves and stunning landscapes strewn with such lovely modern architecture. A good example is Melling:Morse's Split Box. The split in the roof turns the entire house into a rainwater collection system, while the thick concrete floor acts as a passive solar heat sink.
Architect Gerald Melling writes:
"The Coromandel is a sub-tropical peninsular on the north-west coast of the North Island of New Zealand, an idyllic and remote region offering welcome holiday refuge from the urban stress of Auckland city. The Split Box is a permanently constructed commitment to a site hitherto inhabited only by two caravans and a storage shed. Its location is quintessential Kiwi Paradise - a hilltop on the edge of a coastline.
A desire to actively acknowledge the sea is combined with the need to harvest a water supply - the building is thus clinically cleaved down its middle, a negotiable crack in a rock.
Timber is Macrocarpa (an environmentally friendly species which does not require toxic treatment) rough-sawn externally and left to naturally weather, dressed and oiled internally.
