  The proposed works involve kitchen renovation, including the installation of new kitchen cabinetry. There is a larder within the kitchen that houses the gas meter. We are uncertain whether the wall enclosing the larder is load-bearing. The intention is to remove this small wall to allow the new cabinetry and worktop to extend seamlessly across the space.
