The play of water was a strong theme in the design, and several water features are intended to evoke the movement of water in the natural environment. Water forms a physical connection between the Cathedral, Upper Lawn, Terraces and Lower Square.
The hexagonal paving pattern, another notable aspect of the design, is discussed in detail on later pages. It provides a non-directional, unifying ground plane element which serves to anchor the cathedral in the square. Created in basalt and Jura limestone, the hexagonal pattern is a visual reference to the geometry of the roof of the cathedral and reflects the pattern of the tiles on the floor of the nave.
In the Lower Square, paving is used to define the key pedestrian routes encompassing water features, lawn, artworks and hard landscape elements.
The vegetation also has major aesthetic impact from a design perspective existing and introduced trees are used to frame the cathedral, provide dappled shade, and in some cases, seasonal colours.
Lawns were an essential part of making the square child friendly. A tall fescue turf grass was selected for its ability to sustain moderately heavy wear, tolerance of shade and drought, and retention of a green colour during the winter months. A restrained plant palette of low shrubs and groundcover plants ensures that spatial definition and foreground interest is provided, without compromising overall visual integrity. The design increases pedestrian amenity by providing discrete areas for different activities, whilst maintaining this greater aesthetic cohesion.
Secondary seating opportunities respond to the level changes across the site a Guilin limestone is used to provide low retaining walls, steps and terraces that double as informal seating elements.
Artworks by Steve Woodward and Mary-Louise Browne provide significant opportunities for contemplation and enjoyment.
