Who lives in a house like this?

One of my “eagle-eyes” has e-mailed a challenge

.Evidently there are two quite separate houses located in BJ within 50M/60M of each other, and they appear to intentionally “mirror” each other - (both reflect several significant and similar personal design features). However, whilst stargazing the other night, one of my “eagle-eyes” spotted a new highlight on the skyline - One of the mirrors had highlighted - (pun?) - and was displaying a “Flood-lit” Flag Pole, flying the England’s Patron Saint Standard.
However, it was noted that the other one of the pair of “mirrors” is apparently not yet in total reflecting mode, for although it does “mirror” with an identical Flag Pole, and has been flying our Patron Saint's Standard in daylight, as of yet it is not taken to highlighting in full Flood-lit mode - after dark !!

Who lives in a house(s) like this ……?
