We recently completed a single storey rear extension on Shore Road, transforming a cramped kitchen into a spacious family hub with direct access to the garden. The addition of skylights and full-width sliding doors made the most of the morning sun and created a true indoor-outdoor feel, perfect for summer barbecues and family gatherings.
