CorTen Planters for Clockwork Building

The Clockwork Building was a complete refurb of a 1960/70’s office building, project managed by Thirdway and landscaping done by Belsize Gardens. We became involved in the early stages when Belsize Gardens and the client wanted 4 large Corten planters at the front of the building to give the entrance a more vibrant natural look.

All 20 planters were made in total from 3 mm Corten steel with a folded base and a double folded top to give extra strength. In the large planters we also added 4 mm stainless steel bracing wire due to the very large amounts of soil being added to each planter. This stops possible panel movement when the soil is being tipped inside.

There were four larger planters all at 60 cm high, two at 11.2 x 3.8 M and two others at 4.5 x 3.2 M. Lighting was designed into all four planters, a bench incorporated into one of the 4.5 M planters as well as a 6 bicycle stand on the most southern planter. The material had to be Corten steel and needed to be pre-rusted which was done in our EverEdge yard in Staffordshire. The supports were our standard buttress design, all at 500 mm centres. Because the back wall of the planters adjacent to the building followed the contours of the building (windows etc) there were no continuous straight lines, but a series of 90°corners. All these fitted neatly on site and resulted on minimum construction time.

In addition to the main entrance planters, there were 12 more planters in the car park area, infilled between the building windows all 250 x 55 cm and 88 cm high. These planters, being smaller, were incorporated with our steel brace system.

Lastly 4 large planters for the roof garden were also constructed, 150 x 110 cms and 880 cm high as well as one “trough” planter, 250 X 40 cm.
