Are you sure? Agreed they are not 5 terraced houses as currently mapped. But bing aerial suggests the three nearest Terrapin Road were built as large detached houses with the furthest two being a single semidetached building. The house numbering, if correct, also seems to correspond. Bing satellite shows possibly two gardens behind 186, so might be converted to flats (but probably up/down rather than side to side. 188 looks like a single garden. 190 is too blurred to tell.
