Location: Waiheke Island, Auckland
Completed: 2015
Architect: John Ingham of Archoffice


Understanding the environment where window gearing is required is paramount in the decision-making process for operable windows. This can range from the physical location of the building, climate and the uses of the area.

This elegant holiday house on Waiheke Island, designed by architect, John Ingham of Archoffice, incorporates natural ventilation.

The clerestory windows along the eastern façade admit morning light, as well as providing passive ventilation. By using discreet TOPP C20 electric chain drives we were able to provide the owners with the ability to open & close these high windows simply by pushing a single switch to guarantee effective air circulation.

The use of 230-volt motors eliminates the need for special cabling & transformers, making it a safe & economical solution.
