July's Escape - AE Examples in the UK

I spent July in the UK, mostly enjoying myself in the countryside and in London. Several AE related visits particularly impressed me:

• The Eden Project in Cornwall (images) - What a splendid marriage of structure, landscape and MEP.
• Peterborough Cathedral (among others - images) - Like so many gothic cathedrals the structure that has endured 800 years exalts the spirit as good architecture should.
• Alpine House in Kew Gardens, London - (my images) - Like the Eden project a splendid, though far smaller, integration of structure and MEP.

Any of these could be used as excellent case studies in a design class.
