Green Ewarts copper ventilator

This magnificent antique copper roof ventilator is a superlative example of Victorian industrial craftsmanship, manufactured by the prestigious Ewarts & Son of Euston Road, London. Originally designed to sit atop the roof ridges of stables, mills, or grand estate buildings, this functional piece of ventilation has aged beautifully over the last century, developing a stunning and authentic verdigris patina.

The ventilator features a tiered silhouette with precisely engineered louvered slats—sometimes incorporating Gothic arched detailing—designed to create an up-draught and circulate fresh air within the building below. Ewarts & Son were held in such high regard for their metalwork that they were commissioned for landmark projects at Buckingham Palace and the Bank of England, ensuring that this piece carries a significant architectural provenance. It typically stands on a robust square pedestal base and is often topped with a decorative spire or spherical pinnacle.

At Warehouse701, we find that these large-scale copper vents make for exceptional sculptural elements when reclaimed for the garden or courtyard. Their impressive height and historical weight make them ideal for use as a unique garden ornament, a striking interior design feature, or even retro-fitted to become a dramatic outdoor lamp. It stands as a rare and beautiful survivor of 19th-century engineering, ready to bring a touch of industrial elegance to its next setting.
