Interesting question, although off the top of my head I can't think of anywhere where there are existing houses fronting directly on to a canal towpath - as opposed to across a road, as at Lockside.
But then I'm not convinced that these people at MCS know very much about architecture, even though their listed committee officers include a 'hon architect'. For example, their letter of opposition to the development claims that these houses are three storey, not two-and-a-half storey, as described in the planning application. But any architect will tell you that one-and-a-half or two-and-a-half storey means that the 'half storey' is inside the pitched roof area, with dormer or velux windows, which is indeed the case with these houses.
