I know you all liked the plan of Mark's studio and TTC thought the image below may also be interesting for you. That's a detail of a "photo" of Mark's house in London; looks pretty normal :-)
What's interesting are the glazed frameless doors at the back of the house - leading to a nice and more or less spacious garden with loads of green. I guess the doors let lots of light in and create a cosy atmosphere in the evenings. Ahem, yeah, and you can see three windows, but the house has lots more windows ;-) As for most properties, the garden/house is surrounded by walls, so privacy is guaranteed.
