Another challenging issue in this project is an existing concrete slab on the site that measures 12' x 24'. The slab appears to have no reinforcing in it and lies just within the setback limits of the EPC wetland line. With a desire by the owner to utilize this concrete slab for an auxiliary storage building instead of going to the expense of demolishing and removing it, an element is designed to provide usable space on the slab. With no reinforcing in the slab, a separate structure must be designed to support an overhead plane. This structural support however, must be outside the wetland setback area. The solution presents itself as a pair of reinforced masonry piers that plant themselves away from the slab to be within the setback limitations. These piers support a pair of cantilevered steel trusses which suspend a floating, curved roof plane just above the lightweight masonry walls which enclose a space at two edges on the slab. The other two edges of the slab are enclosed by a simple, screened, rough sawn cypress curtainwall and screen doors. |
