Leodis Square, Sweet Street
What we did
Following on from the long standing relationship, Palmers turned to Green-tech for their landscaping materials. Involving importing 550 m3 of Green-tree lightweight roof garden substrate through narrow walkways up to the podium courtyard gardens, this was a complex project. Using their wealth of experience of transporting substrates to elevated areas, the Palmers team decided to blow the substrate utilising a specialist topsoil pumping wagon.
Manufactured from an environmentally sustainable compost of recycled materials and lightweight aggregate, the Green-tree roof garden substrate was purpose mixed for this site to be lightweight and free draining.
The tight city centre restrictions and requirements to keep a steady flow of substrate for the topsoil pumping wagon, meant that the Green-tech team and Palmers team worked closely together to coordinate timed, scheduled deliveries accordingly. This meant the teams worked weekends and evenings to adhere to these movement restrictions.
Overall, it took seven days to complete the import of the Green-tree substrate, this was delivered to the site on a grab wagon. Then transferred to a pumping wagon and over 100m of pipeline was used to transfer the substrate over. Smaller planted areas, adopted a conveyor method where the substrate was placed on the conveyor belt tipped over the walls and barrowed to site.
Social spaces between the 4 buildings was created with the imported substrate mounded in plant beds and large turfed areas in the central courtyards.
Taking two years to complete, the Leodis Square project took two years to complete and won Palmer Landscapes a BALI Award 2020 on the category Roof Gardens/Living Wall Installations – Residential Roof Garden or Podium Landscaping – under 250k.
