Overview
The villa is an important example of late 19th- to early 20th-century residential architecture in Auckland. The restoration included replacing the original Marseille clay tile roof with new Made in Italy Marseille tiles to preserve visual coherence with the existing architecture while improving durability.
A modern cold-ventilated roofing system was developed, incorporating breathable waterproof protection, continuous passive ventilation, vapour control, and insulation. This system helps regulate temperature and vapour movement, improves indoor air quality by reducing humidity and the risk of mould growth, and can deliver energy savings—enhancing comfort while extending the service life of the roof structure and substrate.
The original lead chimney and apron flashings were redesigned and replaced with 0.80 mm copper to improve performance and reduce future maintenance. The balcony was rebuilt, with new copper apron flashings, a door tray, and a drip pan connected to the gutter to ensure watertightness and proper drainage.
The original flat roof (previously steel) was replaced with a new copper standing-seam roof, including a hatch for roof access.
The project was completed with premium 0.80 mm OG-profile copper gutters (330 mm), made in Italy, supported on heavy-duty copper brackets mechanically anchored into the rafters. This fixing method creates a rigid, non-adjustable installation with exceptional load resistance, ensuring perfectly straight gutter lines and long-term durability.
All copper component joints were brazed, ensuring long-term watertightness and structural integrity.
