Ashtead, architechture, authorship and a daylight quiz!

We are at Ashtead with Ann--one of Mary's flatmates and her husband John--retired architect now hospital chaplain and Ph.D student. Ann is the author of books on childhood development....see pics

They have recently redeveloped their house -including a spectacularly shaped lounge room, which is not rectangular--due to an odd-shaped plot, and a vaulted ceiling, which adds a lot to the appearance......again--see below, including pic of the house from the garden.

Finally, there are two pics showing the garden from the house. One is morning, one is evening--you have to guess how many hours separate the two pics!
