    To maintain visual harmony, the replacement wall will use LBC Cotswold bricks and matching mortar to mirror the property’s exterior walls. The restoration is a like-for-like replacement maintaining the wall's original footprint and height. While adding a set of new capping stones, this prevents water ingress and frost damage, maintaining the wall’s profile and the neighborhood’s overall character. The restoration focuses on balancing long-term durability with estate preservation.
