Designed by Pauley Landscapes director Philip Pauley and developed by engineers Waterman Group, the Urban Tree Planter allows trees of up to 12m to be planted without impinging on underground services.
"I wanted to find a way of getting more trees into the urban environment," said Pauley. "The modular system allows you to plant trees in sensitive locations such as living roofs, and ensures the tree only encroaches its own area."
Measuring 2m3, the box with the tree will weigh around 20 tons and will cost between £10,000 and £20,000 "depending on the site".
"It addresses the urban heat island effect and brings in biodiversity," said Pauley. "But the health of the tree is what's most important, so it's a short-term solution by tree standards - you will only get 15 to 20 years."
The company hopes to carry out its first installations this year, and later to roll the service out as an investment vehicle, he said.
