Window Stone WS3 is a stunning contemporary feature crafted from Portland Stone, which combines both a window stone feature and is then core drilled once again to accommodate a hose for water flow. This window stone can accommodate a powerful window of water or a reduced flow with a more gentle trickle. The addition of waterproof lighting is recommended for improved evening visuals. Careful placement with regard to the sun’s position could allow this window stone to be flooded with golden light at sunrise or sunset.
