Kursaal Centre, San Sebastian

On the shores next to the city of San Sebastian sits two opposing glass cubes housing a congress center, a theater hall, exposition hall and cinema. This beautiful building by Rafael Moneo is made of planks of solid translucent glass; though the glass you can see into the building and the shadowy figures as they go between the different facilities. The building has 'windows' of clear glass in the opaque glass panels, and these frame views to the ocean.

Cite de l'ocean et du surf, Biarittz, France

Steven Holl's new surf museum in Biarittz occupies a fantastic site, with landscaped connection down a valley to one of the local beaches. Its forms emulate skateboard ramps and flowing waves and it contains exhibits about the coast, the surf and weather of the region.

Does it work - questionable! its external spaces are austere and hot in the summer sun; the glass of the restaurant and cafe are not protected form the sun even with their new tech sandwich panels, and the use of the site and its connection with the landscape is unsuccessful - seeminly wasteful. It is, however, a great credit to the city to commission such a significant piece of architecture in such a prominent site with such an ambitious brief.

Just on the headline near Cote Basque in Biarittz is an old aquarium that has been updated by cutting a new large tank into the rock http://www.museedelamer.com/. You enter at ground level and work your way up through the building until you emerge on top of the headland where a new grass covered glass box contains a shop.
