Blackpool is exposed to strong saline winds bearing large quantities of airborne sand. The granite surface material needed to reflect the traditional segmental arch pattern but avoiding the use of cropped setts, which had been rejected by the access groups. The solution was four colours of setts with five sizes and varying depths to accommodate vehicular traffic. A variant textured surface was also used to define the carriageway. In all 60 different types of sett were need to create what looks on the ground like a simple fan pattern. Liaison throughout the detailed design process with the Councils engineers and public transport providers ensured all materials would withstand these pressures. In Blackpool sand gets everywhere and water features are no exception. Within the square two features have been introduced and both have required careful detailing to avoid damage by sand and feature automated adjustment of the jets proportional to the wind speed. Blackpool’s environment conditions make most metallic surfaces within a mile of the seashore prone to corrosion. The sculpture commissioned by Blackpool Council- The Wave – is mirror polished Duplex stainless steel, which acts like a hall of mirrors. Patterning derived from the winter gardens and stained glass of St Johns Church was cut into the steel, then inlaid with glass and colour change lighting. A figure cast in clear blue resin dives from the wave top, gesturing towards the seashore adding a dynamic energy to the square and contributing to Blackpool’s illumination heritage.
