One of the local developments that I am keeping a regular eye on is this one in Ham Farm Road. It is approached via a long lane, close to the junction with Upper Ham Road, and the two houses there are set behind, and hidden by, the other houses in the road.
With various extensions the house has at least doubled in size but the new roof and rendering so their best to hide the differences between the old and the new parts. It is a fairly simple design and I think that works well. It also closely matches its neighbour on Upper Ham Road.
As the building work has continued a large gate now blocks this view.
