A floating areaway system which can respond to changing soils conditions (such as freezing, expansion, settling, or the like) utilizes a continuously adjustable attachment to the foundation or a free motion support. The system is particularly adapted to overhanging areaway enclosures such as may include an escape dement. The designs can range from slidable retainers to elastic members to rotating elements so that the areaway enclosure can move up or down with the soil. Shields, low friction surfaces, and waterproof elements can be included to assure continuous operation. Installation, whether new or retrofit, is facilitated through individual free motion support brackets which can accommodate previously installed areaway enclosures as well as a new enclosure. The brackets can be designed to be specific to particular designs, generic, removable, and reversible so that the mounting can be in either the interior or the exterior of the enclosure. Integral designs afford efficient manufacture and installation.
