Abstract: The invention pertains to a housing assembly for electrical or electronic built-in components, with an outer housing feature two lateral walls, a rear wall, a front cover, a roof and a floor, and an inner housing that is lodged with spacing from the wall parts of the outer housing. In a visually appropriate design favorable conditions for ambient weather influences can be provided simultaneously, in that the roof of the outer housing is constructed such that it is curved convexly upward and drops off toward the lateral walls, such that the front cover is curved convexly toward the front, and that the transition between the roof and the front cover is formed of an obliquity that drops off toward the front.
