Two buildings, one smaller ‘cottage’ scale to the street and one larger to the rear and the garden, with a 'sitooterie' in the courtyard space in-between.
The courtyard could be a useful private space, with a sheltered microclimate.
The layout would enable independent access to each part. An adjacent home and business premises could co-exist without disturbing each other. Or it could be great for seasonally sub-letting part of the house.
