Detached historicist two-storey building, with classical construction and three symmetrical avant-corps emphasizing rustic edges. The central avant-corps with three vertical axes is accentuated by a high portal in the centre of the ground floor and three windows on the first floor. The side wings are divided into two fields with two windows each. In front of the building there is a small green area and a playground on the side. Behind the central building there is an auxiliary building built later and a smaller building on the coast with a harbour. A few years ago, a new hall of contemporary architectural expression was built near the central building. Since 1960, the school has had a student dormitory "Tomislav Hero", intended for school students. Classes at the school are held in three buildings with specialized classrooms: nautical cabinet with nautical desk, cabinet for auxiliary ship engines, physics cabinet, computer room, ship engineering classroom with ship engines, workshop for exercises, a library with a large book fund, four boats for seafaring skills, etc.
