I think the road you want is called Dean's Walk. The post code is GL17 9JU.

But to make sure I'm looking at the correct family. I searched for Walter Green living in Harry Hill. I only found one. Born 1899. Father Alfred, mother Emma. Is that the correct family?

Assuming it is:

It looks like the house is no longer there. There's a lot of more recent building in the area.

You can find the exact location from the 1910 land survey site.

The entry is at https://www.glos1909survey.org.uk/code/data.php?id=34418

You can see the hereditament number is 923. 923 on the map can be seen at https://www.glos1909survey.org.uk/maps/Box31/D2428-3-31-03.jpg. It's almost dead centre. You'll have to zoom in to read the number.

This is the street view of the house currently on that spot https://www.google.co.uk/maps/@51.8523533,-2.5114573,3a,75y,90.95h,92.52t/data=!3m7!1e1...
