School Building and Opening Hours

A learning oasis in the Suurstoffi district.

Our modern school building is ideally located in the Suurstoffi district – a car-free, eco-friendly residential and business area with excellent road and public transport links. Why don’t you drop by for a visit and see for yourself?

School Building

Our Preschool is ideally housed in a carefully refurbished historic building with an attached playground. Right next door is a spacious multi-purpose hall, which also serves as a cafeteria and for school events.

The primary and secondary schools are located in our state of the art school house which opened in 2014. Various specialist rooms - an arts and crafts room, a music room, a library, a laboratory for science education - as well as a basketball court and playground promote student-centered teaching.

An added benefit is the spacious playground between the preschool and primary school house. It is a well equipped playground where the children can move unencumbered.

The Suurstoffi is a privileged location. It stands in the middle of a traffic-free area among residential and business districts with excellent access to public and private transport. Developed on ecologically advanced principles, the Suurstoffi is an ideal location for the SIS.
