Centuries of Water Management and Architectural Mastery
The story of Oude Delft 35 began in the early 16th century when it was constructed as a luxury residence for Jan de Huyter. Its striking Brabant Gothic facade, adorned with intricate stone carvings and historical coats of arms, made it an instant landmark in the historic canal district of Delft. In 1645, the Hoogheemraadschap van Delfland acquired the property, cementing its status as the nerve center for regional flood control and water management.
For nearly four centuries, the building has symbolized the Dutch struggle against—and mastery over—water. The exterior of Oude Delft 35 features a spectacular display of heraldry, showcasing the coats of arms of various dike-reeves and administrators who shaped the region's defense systems. Today, it remains one of the few places in Europe where medieval administrative history seamlessly blends with modern civic duty.

Sustainable Conservation Plans and the Path to 2027
Maintaining a 500-year-old stone structure in the face of modern climate challenges requires innovative engineering. Throughout the remainder of 2026 and heading into 2027, preservationists are implementing non-invasive climate-control upgrades at Oude Delft 35.
These initiatives aim to reduce the building's carbon footprint without compromising its delicate interior woodwork and historic paintings. Municipal planners in Delft hope this project will serve as a blueprint for retrofitting other historic properties across the Netherlands, proving that ancient heritage can coexist with sustainable technology.
