The project utilises porphyry cubes with detailing of the guilloche threshold panel picked out in flamed basalt. Two colours of poprphyry are used: mixed reds for the bulk of the paving with a reasonably homogenous pink porphyry used to empasise the outer edge of each of the fans.
The fan pattern, sometimes referred to as Florentine or Fleur-de-Lys pattern, was scaled to best suit the scale of the project and the sizes of setts available. Successful construction of sett fan patterns relies on there being a selection of sizes available, from 50-60mm to 100-120mm plan size, as this enable accurate curves of various radii with reasonably consistent joint width and minimal trimming. Further detail regarding the installation of sett fans and bogens can be found elsewhere on this website.
