The conference complex Sånga-Säby is situated on the island Färingsö in lake Mälaren. As a complement to the existing buildings Tovatt Architects & Planners designed a new auditorium. The new auditorium will increase the capability to host larger conference groups and will create a new appearance for the building. The proposed extension is a combination of new elements and the existing structure; a section of the upper floor of the existing building is demolished to make room for the new volume. This new building structure is kept independent, allowing continued activities in the lower level while the extension is under construction. The new auditorium will be the first a visitor to Sånga-Säby meets. A glassed wall behind the podium will showcase the indoors activities to the outside, as well as giving a framed view from the inside of the oak trees in the gentle slope towards the lake edge. Tovatt Architects & Planners also designed the addition of 65 seats to the auditorium and an extension of the dining area as well as a number of smaller and bigger commissions to develop and maintain the complex.
