Here's a throw back to a project we undertook to install a water feature in a apartment block in York.
These apartments were right next to the river & the underground car park (where our plant was) had to have major flood prevention considerations implemented into the build.
The project's brief also required a real living tree to be part of the water feature (as artificial trees did not meet fire regs), so we had great fun making sure we didn't kill off the tree with the chemically treated pool water!
