Location Q: Scotties House

In the second episode, I recognise the locations of Scottie's apparent neighbourhood being clearly Hampstead including picking up the morning papers on Flask Walk and filmed bits in and around the Heath...

So, I'm guessing his fab Modernist house the EXT we see in Episode one (sorry- I don't have a screen capture example as vsual cue & have had no luck Googling on locations used in the series.) is somewhere in Hampstead?

Any IMDB-er seen this series & is local Londoner into their Architecture sites perhaps & can help me out??

TIA :)
