Accessories for Welsh Slate Water Features


Slate Window Stone WS11 is a great alternative to the traditional garden stone monolith. Window Stones provide a frame for unique view, acting as a focal point and centre piece stone water feature in small and medium sized gardens. Larger gardens can of course also find homes for Window Stones, as they integrate well as part of a more substantial landscape design. In addition to the main core drilled hole this piece is also drilled vertically to allow for a water flow, completed with our additional Large Reservoir Pack that can be purchased in the Basket. Careful placement with regard to the sun’s position could allow this window stone to be flooded with golden light at sunrise or sunset. Alternatively, the window can frame a favourite plant or area of a garden.
