Parties Tendering will be required to deposit the sum of two guineas for copy of quantities, which will be returned to them after opening of their Tenders.

Identical notices to that above appeared within The Cardiff and Merthyr Guardian Glamorgan Monmouth and Brecon Gazette on the 9th June and in The Cardiff Times edition of 10th June 1864. These advertisements from the local press and 'The Builder' appear to confirm that Samuel Dobson was not the architect of the Customs House, etc. but I feel sure, however, that he would have had a say in the choice of design. The final design iterations appear to have been undertaken under the experienced supervision of the firm of George Edward Robinson the well known Cardiff architect on behalf of the Penarth Company.
