The Senate House on the left and Gonville and Caius College (first founded in 1348 as Gonville Hall and re–founded under its present name in 1557) on the right.
The 'student accommodation' pic is actually the library of Darwin College - I don't think any of it is student rooms. One of the nicer examples of 1970s (?) architecture in Cambridge, I think. Incidentally the old part of Darwin (just visible on the left) was owned by Charles Darwin's family.
