    The original design proposed a full white render finish with a charred timber-clad, single-storey side extension. Our amended design retains the white render on the first floor and introduces red facing brick to the ground floor and chimney. The proposed material palette establishes a strong contextual relationship with the surrounding streetscape. By introducing red facing brick to the ground floor and chimney, the design directly references the architectural vernacular of neighboring properties, which typically feature brick ground floors and rendered first floors. The brick chimney honors the traditional brick gable ends of adjacent homes. This strategic use of materials ensures the new dwelling sits comfortably within its established context, successfully balancing local heritage with a modern, contemporary aesthetic.
