This construction is an enlargement of the left-hand section in Model for 'Double Relief in a Niche' (1929-30). Despite its mechanistic appearance, it was designed for a domestic setting, though the project was never realised. Gabo's works for niches developed from his early interest in sculptures that extended across the actual space of a room, which he shared with such Russian artists as Vladimir Tatlin. Here, the curved and rigid forms define the space within and beyond the box.
