The town is principally a linear development along Main Street and High Street, with narrow burgage plots at right angles to the street. These are particularly well preserved on the north side of Main Street.
Medieval development also extended along Church Street, the earliest recorded street name in Frodsham (1272), where details of burgage plots survive from about this date. The description of plots lying between
the road and further burgages perhaps implies a second line of properties behind the street frontage. C13th and C14th burgages are also recorded.
