Another day another jigsaw puzzle! We were commissioned with undertaking this path in Christchurch. The stone is Halswell stone which is a type of Basalt. It is one of my favourites, with varying colours and tones including a leopard type lichen growth.
The finished product pre-grouting. Groutlines 10-12 mm.
When wet the colours and tones of this stone really come to life. The round drain allowed for a "rain chain" to drain from the porch guttering, providing a unique feature near the front door.
