Presumably plans for applications under building control regulations
In many cases the records are unnumbered plans pre-dating the main sequence beginning in c1914 (see RDC8/8/Y2)

Researchers should therefore be aware that this group may contain some of the missing plans in the main sequence
Names, addresses & dates are listed to aid identification
