Secondary Technical School Na Třebešíně was built around 1973 as a modern experimental complex and its area includes buildings with classrooms, workshops, specialized classrooms, managing director´s office, a gym with a swimming pool, conference hall and accommodation for students. The complex was built as an experimental school with a fresh architectural expression.

Architecturally, the most interesting part of campus is conference hall, which was designed with reference to the architecture of the late 60s of the 20th century. From the outside, visible deltoid shape arrives form ground plan shape. The mass of conference hall is attached to mass of principal building in a way that it looks like it is partly blended into it. This dominating feature is visible right from the main entrance to the campus. The ground floor partially serves as the technological part and storage. Access to the hall is designed via a staircase. The main supporting structure is made of monolithic reinforced concrete column. Other interior horizontal structures are designed as reinforced concrete floor.

The aim was to revitalize the interior and equipment of the hall to suit current requirements. New surfaces, acoustic cladding, ceiling, furniture and equipment facilities for lecturers have to be designed for this space. As new feature, method of projection and audio communication was added and new solution of air exchange and provision of heating and cooling. In the interior we didn’t find any preserved and valuable architectural details. Despite the many changes in the past, architecture of the campus still carry the spirit of 70ties. That is why we connected to this architecturally spirit and designed interior of this hall in that way. Art istic design solution of the hall is strongly influenced by polygonal architecture of that period and its geometric composition. It is influenced by Czech sculptor and glass-maker Stanislav Libensky. The main idea is based on the expressive shape solution of the ceiling and walls as two separate units. Shape solution of ceiling comes from the ground plan shape of the hall and inspiration comes from “open fan” that is why surface of the ceiling is folded in a similar way. The ceiling is formed from stressed foil tied on aluminum structure, which is composed of many connected triangular sheets. Whole area of ​​ceiling can be lighted up, therefore the ceiling looks light and fragile. The walls of the hall are cladded with polygonal formatted sheets of plywood, which are smoothly connected and form a polygonal shaped surfaces. The sheets are veneered with a birch fitted with white semi-translucent glazing so that the wood pattern show through it and preserve the natural character of the interior. White wood tinting is more abstract and make visible various angles of the sheets. Space has more plasticity. Plates has acoustic as well as aesthetic function. Seats and small tables are made of birch plywood and they are covered with fabric in sand color. The flooring made from natural rubber selected in the same shade. There are 125 folding chairs and 100 folding tables in the hall. The hall is equipped with intelligent control system, which allows to control external blinds, dimming and switching lights and audio visual production.
