Plans submitted for approval to Llanrwst Rural District Council. The Council was superceded by Hiraethog Rural District on 1 April 1935.
The plans have been weeded and only plans of new buildings that were approved have been selected. Plans that were rejected, outline applications or plans for alterations and additions to or changes of use of existing buildings or for temporary structures, on the whole have not been retained.
Additional information from the original containing envelopes [discarded for archival reasons] has been included. This sometimes conflicts with information given on the plans themselves.
