This is the Casa da Musica building in Porto, portugal. It was built in 2005, designed by the architects Rem Koolhaas from OMA and is a the 'home of music' in Porto.
Fun fact, it was built on a old disused Tram deport. you know what other famous Opera House was built on a old disused tram depot - That's right the Sydney Opera House.
There are so similarities between the two - obviously the white exterior, where the Sydney Opera House has the famous sails and curves this one is very angular. The isolation of the SOH is quite their in Porto, but it is a stunning building non the less
