The ‘boom’ series is a fusion of two divergent references to function. Firstly, civil engineering - a concern with high-visibility, safety, barriers and other types of controlling devises. Secondly, musical instruments - developed using the tonal quality of strings placed under tension. Stripped of utilitarian function, structures such as barrier booms, bollards and safety gates are re-evaluated for their physical properties and their assertive aesthetics. They are also repurposed sonically via attached musical instrument components. The resulting forms resonate more intensely when struck, creating an additional sound, voice, or purpose.
