After many years in its location at Theo Mann Bouwmeesterlaan 75, the ISH announced in 2002 that it would move to a new location, Wijndaelerduin 1, in Kijkduin. The relocation was completed in January 2007. On April 21, 2007 Queen Beatrix of the Netherlands officially opened the new school building.
Facilities
The school has a total student capacity of approximately 1500 people. It has a 350-seats auditorium inside the school. It also has two full sized, fully equipped gyms. There are two computer labs, six equipped science labs as well as an expanded library. The school has a canteen, designed to fit 200-350 people. Also the school has expanded their capacity by including two-story portacabins which are equipped to the highest standards, with a beautiful view of the school's greenspace. There is also a car park just outside the school. Unfortunately the car park is not part of the school community. There are also parking spaces in front of the school, these are prohibited to use during the day due to the limiting of CO2 emissions from cars. There is a car park for staff on the school campus who are privileged to do so, student parking is unavailable.

The primary school offers the International Primary Curriculum for students between the ages of 4 and 11, while the secondary school offers the International Baccalaureate Middle Years Programme for students between the ages of 11 and 16 and the International Baccalaureate Diploma Programme for students between the ages of 16 and 18. All lessons, apart from foreign language courses, are taught in English. The study of Dutch is compulsory for students except those in the IB Diploma Programme. The ISH supports mother tongue education, current provision including Dutch, French, German, Spanish, Italian, Portuguese and soon Romanian and Chinese. For those students whose native language is other than English, or for those with little familiarity with the language, the ISH offers English support lessons in both “beginner” and “transition” levels. Crash courses in English for beginners are provided in the Learning Support Centre. Support for Special Educational Needs is available. The school also offers a wide range of optional after-school activities, including music lessons.
