Where is the Taskmaster house?
The nearest train station is Chiswick (mentioned in S1E5 where Frank Skinner takes a boulder on a train so that it is as far from the house as possible).
It also looks like it's on a busy road...
It's in Dukes Meadow, Chiswick. On the corner of Chiswick Bridge Road, Hartingdon Road, Dan Mason Drive, just south of Unicersity of Westminster Sports Ground and Roko Health Club.
On Googlemaps it's got loads of vans in the drive way.
So it is!
Thank you, how on earth did you know that, or did you work it out?!
I wish I could say I had some magic skill - but once I knew it was filmed in Chiswick, I googled about a bit and found an article on ukgameshows that mentioned Dukes Meadow

From there it was just a case of google maps!
