Description
46 and 47 Commercial Street in Penygloddfa, Newtown, are a pair of three-storey industrial houses with cellars and weaving lofts. The buildings are roughcast over brick and feature a gently pitched slate roof with saw-toothed eaves cornices and brick end chimneys.
The former weaving lofts have shallow two-light casements without sills, while the first and ground floors retain small-paned iron lights in cross windows, which have cambered heads, shallow reveals, and stone sills. There are central doorcases with leaded dripboards supported on brackets, and the original six-panel doors are still in place. At the rear, the weaving lofts have three-light casements.
