Barker Road houses c.1925 (annotated)

Cropped from Barker Road houses c.1925.

The photo shows four buildings with their addresses (house number xx The Peak). From the left:

The Peak Building
455 455 The Peak, R.B.L. 150
454 Tantallon - RBL 121 - Barker Road
453 Capsuimun / Tai Wo, Barker Road
452 The Cottage

There is another building between numbers 453 and 452. I don't think this is a building for residents but a garage or servants' quarters. Any better ideas are welcome.
