A Forest for a Moon Dazzler, designed by Benjamin Garcia Saxe, sits in the rainforest of Costa Rica. The bamboo house is designed to give the occupier - the architect's mother - a direct view of the moon while she goes to sleep. At night, the cone-like surface opens up so she can see the moon.
The awards were handed out during the festival in Barcelona. The judges remarked: "The architect has addressed the practical and emotional needs of his mother's security by creating a home for her to occupy alone, while also satisfying his inventive curiosity."
A photographers' website is championing the preservation of images of the UK's urban landscape by establishing a national collection of rapidly disappearing everyday street scenes.
FotoLibra is asking photographers to submit snaps of ordinary streetscapes showing unmodernised shopfronts and buildings before they are demolished to make way for new development. The aim is to create a permanent record of UK street views complete with traffic, passers-by and advertising.
Founder Gwyn Headley fears that the unique character of some towns and cities is rapidly being lost. "The preservation and recording of historic buildings quite rightly gets a lot of attention, but the ordinary streetscape slips under the radar," he explains.
"We want to build a national archive of images of our disappearing urbanised world, complete with shop windows, cars, fashions, hairstyles and even advertising billboards. All of these date the photograph to a specific moment in time that can never be recaptured."
Photographers can upload their images free to www.fotolibra.com and will earn fees on images subsequently used for commercial purposes. The library is particularly interested in photographs taken before 1980.
Westminster City Council has decided that flouting planning regulations by projecting an image onto the side of Big Ben just isn't cricket.
As Planning went to press, the council was considering legal action against Cricket Australia after a holographic image of Ricky Ponting and Michael Clarke was projected onto the tower without permission.
The display includes the message "Don't forget to pack the urn", referring to the upcoming Ashes series in Australia. The council has written to Cricket Australia seeking an explanation of its role in the stunt and is awaiting a response.
The unauthorised display of an advertisement is an offence under section 224 of the Town and Country Planning Act 1990 and could trigger a fine of up to £2,500. Westminster's deputy leader Robert Davis says the Big Ben display is "inappropriate and insulting".
"Although we have not prosecuted previously because such stunts are usually over quickly, we feel that enough is enough. Unless we take a firm stance, this style of guerrilla advertising will only increase, particularly in the run-up to 2012."
