A family friend was planning her wedding and her mother, a skilled flower arranger, asked me if I could build a structure on which to mount a flower arrangement outlining the entrance archway of the church. The brief required that the arch safely support the mass of the flowers and the damp floral foam that would keep the flowers in good condition. Some mass estimation suggested that this could amount to over 10Kg, potentially higher. The inhibiting factor was that the arch needed to mount inside the existing stone arch of the church, without any damage occurring to the fabric of the building. I took measurements of the archway and designed an arched truss structure, which would enable floristry foam in polymer cages to be attached to it. The anchoring system was based around putting the arch in compression, using the top of the stone ‘pillar’ relief on either side of the door and jack screws that pressed against the inside of the stone archway, using wooden pads to eliminate the risk of damage. The arch was produced in several sections to enable more compact storage and transportation when not in use. The final product worked perfectly and has been used several times since the wedding that it was originally produced for.
