What is possible?
Every organic planter can be tailored to your project.
Round or oval
Ronda and Vora are round, Ovalu is oval: three basic shapes that together cover most organic layouts.
With or without base
Without a base for planting directly in the ground, with a base as a movable planter.
Custom dimensions
Ronda from Ø350 to Ø1500mm, Ovalu from 1200x800 to 2800x1600mm, and larger on request.
Colour of your choice
Besides the natural Corten steel patina, every model is also available in almost any RAL colour.
Tailored planting advice
Our specialists advise on which plants, grasses and perennials combine best with your planter.
From first conversation to custom delivery
Four steps, from your wishes to the installed planter.
1. Understanding your wishes
We discuss shape, size, material and location, so we get a clear picture of your project.
2. Designing your planter
Together we choose shape, material and colour, with tailored advice for the best solution.
3. Made to measure
Every planter is made to the specified internal dimensions, with welded seams and a reinforced rim. After installation, Corten steel gradually develops its characteristic rust-brown patina.
4. Delivery
We deliver your planter with care and install it if you wish. We always confirm the exact delivery time with the quote.
