Curved main facade of the Gibraltar hotel

used in conjunction with prestressed concrete flooring units. Devised by Mr. Jan Bobrowski, the company's con- sulting engineer, the components have several unusual features. Steel shoes, protruding vertically from each unit, permit rapid welding together on site. The hori- zontal, reinforced section of each unit is pierced by five longitudinal tunnels and strong steel cables are strung through these and affixed during erection. Portland Capstone is used in the concrete mix to give qualities of strength, lightness and whiteness.

The Gibraltar development will combine a 14,000 sq. ft. ground-floor shopping centre, a three-storey car park, and five floors of hotel with recessed balconies and a roof-top restaurant.

Above the ground-floor shopping centre, the three car park floors will have a jewel-like treatment of the double-diamond shaped units, providing a screen to the cars, with open end-walls to give good cross-ventilation without pumping. Strength and stiffness of these com- ponents when fastened together is such that the walls will support the whole weight of the hotel above and the structure will be fully self-supporting at all stages of construction. The finished facade will also have to be strong enough to withstand windspeeds of 100 miles per hour.

Architect is Howard V. Lobb.
