Planter boxes · Cylinder Series
Sculptural cylindrical planters in aluminium — as standalone features, in clusters, or as tree risers. Curated custom sizes, finished to your palette.

The sculptural form
A round, considered form that softens a scheme and holds a space on its own. Against the angular ranges, the cylinder is the deliberate counterpoint — quiet, sculptural, and confident enough to stand alone.
Spun from the same premium aluminium as the rest of the range, so the material story stays consistent across a project — only the geometry changes. Corten is a considered option where a scheme calls for a weathered palette.


Compose it
The sizes are designed to group. Mix diameters and heights into an arrangement that reads as one considered gesture, not a row of matching pots.
Where it goes
The considered menu
Rather than an open-ended custom form, the Cylinder Series is offered as curated standalone pieces and held size sets — designed options that compose well and specify cleanly.
Share the setout and we’ll present the considered menu with the pieces that suit.

The held size sets
Four standard diameters, each in four heights — 400, 600, 800 and 1000 mm — proportioned to group into clusters. Larger feature diameters add taller heights. Dimensions in millimetres.
| Diameter (mm) | Heights (mm) | Class |
|---|---|---|
| 600 | 400 · 600 · 800 · 1000 | Standard |
| 800 | 400 · 600 · 800 · 1000 | Standard |
| 1000 | 400 · 600 · 800 · 1000 | Standard |
| 1200 | 400 · 600 · 800 · 1000 | Standard |
| 1500 | 400 – 1200 | Large-format |
| 2000 | 600 – 1500 | Large-format |
1500 and 2000 mm diameters are large-format feature pieces, made to order. Exact custom proportions on enquiry.
