Furniture manufacturer Vitra’s grassy headquarters at the meeting point of France, Germany, and Switzerland (just outside Basel) has been an architecture destination since its Frank Gehry–designed museum opened in 1989. There are also buildings by Zaha Hadid and Tadao Ando, but the most remarkable sight may be the new showroom and store designed by the Swiss firm Herzog & de Meuron. The architects have taken the archetypal pitched-roof house, elongated it, and stacked 12 of them up like fireplace logs. Inside, you can follow winding staircases through the dreamlike space and look for home furnishings.
