Portland Stone Stack PSS1 measures 1 metre high and can be used as a stand alone Stone Sculpture. This is a similar style to our Slate Pyramid Stacks but consists of core drilled flat 20mm Portland Stone pieces with a mix of sawn and rough natural edges. The addition of our Small Reservoir Pack transforms this sculpture into stunning garden water feature.

Portland Stone Stack PSS1 comes with a bespoke stainless steel stabilising plate to keep the structure safe and secure. The creamy Cotswolds style tones of Portland Stone are perfect for contrasting against careful planting choices in any garden design.

Portland Stone Stack PSS1 is a garden water feature measuring 1 metre high. Core drilled pieces of Portland stone with a mix of sawn and naturally cut edges. These work equally well as a working water feature or a garden sculpture. These can be made to any required size on request. Portland Stone Stack PSS1 has to be used with the included stainless steel stabilising plate. Each piece just slots on top making this a very lightweight structure to manoeuvre into place.

Ideally placed to create a focal point in a garden Portland Stone Stack PSS1 suits a number of styles, from modern contemporary garden designs to more traditional designs. Also work very well in amongst greenery and borders with splashes of colour. These can also act as divides and boundaries within garden spaces to help zone different areas and provide a focal point at the same time. Lighting at various levels and angles will create an attractive sculpture in the evening. Read our guest blog Working With Natural Stone in Garden Design for insight from the eyes of an experienced Garden Designer.

A water feature accessory kit can be added to your order to transform this sculpture into a working water feature. Due to these being very narrow, this will fit easily onto our Small Reservoir Pack with a Finia 650 reservoir. Please see our Customer Gallery for previous slate paddlestone water feature installations, stone monoliths, stone pyramids and garden design ornament ideas. Please contact us if you have any questions or queries or would like to commission a bespoke design for your own garden.
