I first visited Potter Heigham
on July 24 , 2005 and spent 30+ mins driving around but could not find
the building. I returned on September 6, 2018 armed with the info
Jan Tarrant provided more
info in the form of reference to "Timpson's England" by John Timpson
(upon the cover of which is a photo of the building) it stands " a few
hundred yards downstream from the bridge, among more mundane bungalows
that line the bank"
According to the BBC site, the
building is "The Dutch Tutch" and it's downstream of Potter Heigham bridge
because it was too big to go under the bridge.
