Reports, particulars and valuations of properties in the TWC's leasehold estate. Most of the reports seem to have been made to estimate the annual increased reserved rent to be paid by tenants for extensions of leases. ANS 4/1 is a collection of loose reports and valuations, c.1854-1901, brought together for convenience. ANS 4/2-4 comprise original files of particulars and valuations, 1881-1901, extracted from three binders intitled 'T. W. estate, W. Rees' reports'.

Files of reports by Habershon & Fawckner (Habershon, Fawckner & Groves from 1898) of surveys of properties in Newport and Pillgwenlli. Most of the reports seem to have been made with a view to a renewal of the lease of the property, and detail the repairs necessary before a renewal can be granted. Habershon & Fawckner were architects to the Tredegar Wharf estate (at least in 1896; see ANS 5/2, no. 73), although the Tredegar Wharf estate is not mentioned explicitely in these reports, as it is in the reports in ANS 4.
