Magnificent view of St Paul's cathedral's staircase Landmark design, St Paul's Cathedral. Besides this, the London Design Festival has commissioned landmark design installations all by renowned British architects and designers across the city, at the Victoria and Albert Museum and, for the first time, St Paul's Cathedral. At the top and bottom of the cantilevered stone stair winding up the south-west tower to the library, there will be an enormous lens set in a polished polished hemisphere and a spherical convex mirror, designed by architect John Pawson. Ground by Swarovski, this will offer a transformative view of the famous staircase that the naked eye can't offer. @font-face { font-family: "Times New Roman"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: Courier; }table.MsoNormalTable { font-size: 10pt; font-family: Courier; }div.Section1 { page: Section1; } Lego Greenhouse by Sebastion Bergne Lego Greenhouse & Red dress. Representing the more playful side of the festival will be a Lego greenhouse by Sebastian Bergne in Covent Garden or an installation by Aamu Song, taking the form of an enormous red dress made from more than 550 metres of fabric, which a storyteller will wear while the audience sits in its 238 capacious pockets. @font-face { font-family: "Times New Roman"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: Courier; }p { margin-right: 0cm; margin-left: 0cm; font-size: 10pt; font-family: Times; }table.MsoNormalTable { font-size: 10pt; font-family: Courier; }div.Section1 { page: Section1; } Red dress by Bernhard Ludewig Ecopink & Kvadrat. You can't have a design festival these days without a focus on sustainability. Ecopink puts the focus on using the 'alchemy' of art and design, showing how waste products, surplus or recycled objects can be transformed into desirable jewellery, furniture and accessories, while leading Danish textile company Kvadrat partners with renowned designers Ronan and Erwan Bouroullec to create a stripy field of fabric where visitors can relax. @font-face { font-family: "Times New Roman"; }p.MsoNormal, li.MsoNormal, div.MsoNormal { margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: Courier; }table.MsoNormalTable { font-size: 10pt; font-family: Courier; }div.Section1 { page: Section1; } Ecopink exhibit, an ethical-ecological approach to design Design in Science.
