Round House Leeds - Can Anyone chuck any light on this ?

I came across a newsreel on the pathe website from 1939, which shows a round concerete house, situated somewhere in Leeds. Sadly, not much google-able information is given, especially as the family at the house have the surname Smith. 

I have asked over at the secretleeds site, but that has drawn a blank there. Can anyone shed any light on it ? especially where it was and what happened to it.
