North of the canal and stretching up Maida Vale itself were situated large detached houses with gardens. At the start of the constituency's existence most were occupied by a single family, but as time went on the families took in lodgers and eventually split their homes into flats. Along Maida Vale, the 1930s saw the building of new mansion blocks, a type of housing that already predominated along Elgin Avenue and some of the other streets from the time they were first built (typically, the first decade of the twentieth century).
