The buildings were semi-detached and are the buildings closest to us in this 1930 photo:
Number 8 is on the left, and 10 on the right.
The 1938 Street Index (see page 237 / image 435) notes they stood on K.I.L. 576 R.P.
The Street Index doesn't give any names for the buildings, but the photo above is titled 'Eastern House', which I guess refers to number 10. Eastern House appears in three years' Jurors Lists, which suggest it was home to the Prata family:
1925 & 1926:
c | Prata | Henrique Jose | Assist. | A. A. Lopes | Eastern House | Kowloon |
1931:
c | Prata | Frederico | District Engineer | China Light & Power Co. (1918) Ld | Eastern House | Hart Avenue |
The buildings aren't shown on the 1920 map, but they are shown on a map dated 1922. They are then shown on later maps until a map dated 1964 labels the site as 'Construction in progress'. Based on that I've guessed the dates for the building as [1921-1963].
The front garden of No. 10 extended further than No.8, causing a kink in the road. If you walk that section of Hart Avenue today the old buildings are gone but the road still has a kink in it:

8 & 10 Hart Avenue
In this photo from 1927, possibly 8 & 10 Hart Avenue are at the left side.
Left of the Temporary Quarters, a short road can be seen. This should be the first short part of Prat Avenue [1920- ] with 1920s Prat Buildings [????-????]. Further left in the direction of the viewer, the buildings are probably 8 & 10 Hart Avenue. Hart Avenue would run behind these buildings.
The 8 & 10 Hart Avenue buildings should also be visible behind F and G in this annotated photo from 1927.
