Haven't viewed the house yet and the floorplan clearly isn't accurate but it gives one an idea. It's a 1960s-ish ex-LA London house, very overpriced for what and where it is (Foxtons).
From the photos it looks like there used to be a garage at the front and they've converted what used to be the garage door into a sort of glass-doored porch that looks like a security nightmare. What's labelled "garage" is a weird half-converted nothing-space with French windows on to the garden. It apparently has two first floors - presumably the one with the reception room is the actual first floor.
Any thoughts?
