NEW YORK• Summer days are made for meandering museum visits and new additions and locations will offer travellers an array of gallery spaces and exhibitions in Germany, New York City and London.

The Vitra Design Museum has just opened a new building, Schaudepot, opposite Zaha Hadid's Vitra Fire Station on the Vitra Campus in Weil am Rhein, Germany. The ground- floor gallery showcases the first permanent display chosen from the museum's vast furniture collection, including rarely seen works by Charles and Ray Eames, along with recent acquisitions such as Dutch designer Joris Laarman's 3D-printed aluminium Gradient Chair.

In the basement, hundreds more furnishings and accessories are visible through glass walls, including sculptures and prototypes from the Eames estate and classic lamps by Alvar Aalto, among others.

On June 23, the International Center of Photography is scheduled to reopen in a two-level, glass- fronted space in New York City, across the street from the New Museum. The debut exhibition - Public, Private, Secret - is a constellation of contemporary and historic works alongside social media feeds curated in real time.

One room juxtaposes historic mug shots with a stream of modern-day police amber alerts and surveillance footage. Historic photography, such as the suburban living rooms of Larry Clark's Tulsa series, illuminates privacy issues that continue to be debated.

In London, Tate Modern will open a new addition to its existing, 1950s-era power station campus on June 17. Switch House, a brick-clad pyramidal design by Herzog & de Meuron, emphasises physical and digital interaction. Visitors can climb into Ricardo Basbaum's steel cages or take in a floor-to-ceiling, multi-screen display of international artists and their work spaces.

A new Tate app will also launch with background on art and artists featured in the museum and navigational tips to guide visitors towards specific works and exhibitions.

To usher in the new space on June 18, more than 500 singers from London community choirs will perform at Turbine Hall, where the museum's newest acquisition, a 6.7m-tall tree sculpture by artist Ai Weiwei, will stand.
