Greatest "free" bar view over London. The Heron Tower is a commercial skyscraper in London. It stands 230 metres tall including its 28-metre mast making it the tallest building in the City of London financial district and the third tallest in the UK.

I've had a love affair with the BT Tower for some time now. Unfortunately entrance to the public was shut in 1980, but earlier this year I was invited up to the top, where the revolving restaurant once stood. The views were absolutely breath taking.

I trust owner and director Tamsin Clark completely with what I could and should be reading.

I walk a lot; the best way to experience a city. So it's sometimes to do with the way places join up. This cast concrete letterform is a part of the Lycée's gateway. Each of the form's facets arrives at a different character, so six possible letters come from each cast object. I've never been inside the Lycée but always walked through this way up to the V&A, in order to examine again and again how each form works. The surfaces set the tone for the V&A and its incredible Ceramics floor, a perennial inspiration.

Nice old trees, lots of space, good for walking, running, hanging out with your kids and most of all, the perfect place to lie in the grass and chill out.
