The proposed development comprises of the demolition and site clearance of buildings on the Garth Works Industrial Estate and construction of the Taffs Well Depot as indicated on the masterplan (see Drawings 367590-28I-XX-DR-C-0002 and 0003). The proposed development area is situated principally at the site of the Garth Iron Works, which operated from the late 19th century until the late 20th century. The large complex comprised of a number of buildings and warehouses, with only a railway building and row of terraced buildings surviving today. The proposed development area is intersected by the existing Core Valley Line (CVL), as well as being bordered by the dismantled Cardiff rail line to the east and Rhymney rail line to the west. The proposed development area is also bordered by the infilled Glamorganshire Canal to the east and a row of grade II listed workmen’s cottages are situated approximately 30m west of the proposed development area. This heritage statement has identified the key heritage assets which have the most potential to be impacted by the proposed development. Within the proposed development area, these comprise of; ● Mid-19th century railway building and terraced buildings from the Garth Iron Works (undesignated). Within the surrounding study area, the key heritage assets comprise of: ● 1-11 Alfred’s Terrace (grade II listed); ● Existing CVL (undesignated); ● Dismantled Rhymney and Cardiff rail lines (undesignated); and ● Glamorganshire Canal (undesignated). This heritage statement has found that the railway building and row of terraced buildings within the proposed development area have lost their historical connection from the Garth Iron Works which has diminished the historical and communal value they provide. Due to the low value of the heritage assets the weight given to their preservation in terms of planning policy requirements is considered to be low. The grade II listed workmen’s cottages on Alfred’s Terrace are currently screened from the proposed development area by vegetation. Mitigation will be achieved through the design of the new builds within the proposed development area, which extend to a lower height of the current building and will ensure these assets remain screened and no impacts are made on their settings. The proposed development would remove little, if any, historic fabric of the CVL which would remain operational.
