Several of the houses in this style have extended the front slightly by leaving all of the bay intact while extending the front of the window across to the porch. Here the approach is different and the side of the bay has been removed and incorporated into the house. It is more work but it looks the same, i.e. there is a half-bay, so there are no problems there.
The problem is the windows, they just do not fit in. The windows in all the neighbouring houses have glazing bars and without them this house looks odd.
