“Moderna R Liberty”, the accessible version, was installed in the disabled toilets.

This model is more rounded and looks softer.

The choice for the ladies’ counterpart was “Moderna R”. This model's look is flattened and boasts straight lines the overall impression is one of elegance. The men's toilets feature wall-mounted “Moderna Plus” units. This allowed the products, with their thin walls and tight radii, to be even more economical with materials and made them more environmentally friendly. Corundum was added to the product's ceramic, making the it harder. In 2013, with Saphirkeramik, Laufen launched a new kind of bathroom material. Founded in 1892, this Swiss company is considered one of the leading porcelain manufacturers. Sanitary ware by Laufen was chosen for the WCs. The resulting impression, both calm and cultivated, is reflected in the edifice as a whole. And for the interior fittings the architects used the kind of materials that are typical of industrial buildings: The walls are made of rough fair-faced concrete, the floors of unsealed oak. The extension's 10 stories are connected with the original building by means of a bridge. Towering above this is the “Switch House” – a twisting, pyramid-like tower, its façade clad with 336,000 bricks with only narrow slits for window. Two oil tanks belonging to the plant’s former transformer station form the base. Which is why Swiss architects Herzog & de Meuron, who converted the power station on the south bank of the Thames into an exhibition location, designed an extension, which opened in June 2016. Although it was originally designed for two million visitors a year, the Tate Gallery of Modern Art in London has turned out to be a crowd-puller: In 2015 alone, what is now the world's largest museum of modern art attracted more than five million visitors.
