The overall intention is to have, for each house listed, an 'architectural biography' comprising a full history including who built the house, when and why it was demolished and to have an image of the house - be it a photo or a print. However, this takes time and so to make it easier to find those houses for which one has been completed, this page lists them below.
Please note that there are many other houses in the complete list of lost houses which have just images.
