A closet can fit into an attic and a cabinet (105) can be retracted out of the closet to the living space below manually, or using a return spring or electrical means. An air space (150) around the cabinet insulates it from thermal contact with the walls. A panel (110) with vent openings (155) is affixed to the bottom of the cabinet. In an alternative embodiment the cabinet is hung from a restraining member (145), or arm (1105), by which it can be raised for storage and lowered for access. When raised, the panel is in contact with the ceiling (110) between the attic and air from the living space mixes into the air space by convection. A fan (160) can urge circulation between the air space and the living space, reducing of temperature extremes in the air space and hence the cabinet.
