... and talking of new buildings, this is the place where "my" lab once stood:
For comparison, see pictures from half a year ago here and from last summer here.
They are building a huge new complex for Earth Sciences, with a much larger footprint than the old buildings which were knocked down. However, it is certain that they will not be able to build higher than maybe 6 floors, as there are very tight restrictions concerning the Oxford skyline. Certain view lines, looking from the surrounding hills at the famous "dreaming spires" must not be crossed, which limits all new buildings to a very reasonable height.
The tree on the right hand side hides the corner of the former Dyson Perrins Laboratory (organic chemistry lab), an early 20th century brick building which has so far survived the general enthusiasm for knocking down old labs. It now houses something else, I think it's related to archaeology. The building carries a plaque sponsored by the RSC, highlighting it as a landmark of the history of chemistry.
