A planning report from the Vale of Glamorgan Council shows the application, submitted by Mr Mathew Mazhuvanchery, covers 33‑34 Windsor Terrace, where Mint And Mustard operates at ground‑floor level with flats above. The site sits within Penarth’s district retail centre and the town’s conservation area, close to the Windsor Road roundabout and adjoining residential and commercial properties. Full planning permission has been approved for a “proposed new spiral staircase and shop front opening”, designed to provide improved access to the two first‑floor flats. Inside, an internal cavity wall will create a stairwell, with a spiral staircase leading up to the front terrace at first‑floor level while existing rear access routes are retained. Penarth Town Council backed the application, recommending approval, while the council’s heritage officer raised no adverse heritage impact.
