Slate Monolith SM17
Stone Monolith SM17

Stone Monolith SM17 is currently the largest, roundest and bulkiest stone monolith water feature currently in stock. This large garden boulder would lend itself well in a medium to large sized garden as it could be a bit too overpowering in a small design. Large sound quality pieces like this are becoming increasingly difficult to source in the quarry and the work that goes into cutting, sawing and moving these large pieces must not be under estimated.

Garden Water Boulder Water Feature 2
Boulder Water Feature BWF1

Boulder Water Feature BWF1 is a natural stone garden ornament, core drilled to make a stunning water feature. This boulder is a little bit trick, it looks a really big lump from the front but it is actually quite narrow, which saves the weight and makes this much more manageable to move around.

This would make a real statement in both a modern garden or a more traditional rustic style due to it’s soft Cotswolds creams and greys. Lighting would also enhance this feature, the water sparkling in the evening light as it cascades down the natural stone.
