For his first building, the artist Olafur Eliasson has created a brick office-cum-castle for Denmark’s Lego dynasty. Rising out of a former industrial dock, it is a dizzying, dreamlike masterpiece

This year’s event in Cape Town again successfully melded together design superstars with emerging practitioners, but its growing global reputation holds risks as well as opportunities, says John Jervis

Olafur Eliasson and landscape architect Günther Vogt have created an artwork at the headquarters of Kvadrat that recalls earlier times and a much colder climate.

The Hayward Gallery’s show about artificial light in art features some rare, sometimes thrilling installations, but also some misses, says Laura McLean-Ferris.

Hal Foster turns a spotlight on famous buildings, but pays no heed to their contexts, says Kieran Long.

Olafur Eliasson’s reflective facade distorts and amplifies light and colour, making it a beacon ready for the long, dark Icelandic winter.

A scheme to house a series of artworks in a botanic centre in Mexico has grown into an ambitious masterplan that aims to make a similar display of the garden’s “most important collection”.

As the 2010 Biennale winds up over in Venice, Kieran Long asks where the old-fashioned troublemaking was in Kazuyo Sejima’s good-taste, tranquilising exhibition.

Olafur Eliasson and Ma Yansong’s smoke-filled room in Beijing sends Johanna Agerman on a journey of blind, misplaced faith.
