Large public spaces require proportionally larger interventions. Oval Tree Isles measure a minimum of 9m - 30 ft in length and approximately 4m - 13 ft in width, perfect for making vast spaces more welcoming. An outer radius of at least 3m - 10ft is required to install border seating along the short ends of an isle. R&R beams are positioned radially to prevent skateboarders from skating along seat edges.
The CorTen steel structures do not require their own foundation – standard depth below ground level is 15 cm - 6”. A cambered fill allows trees with larger root balls to be planted. Larger trees should be securely anchored using a special-purpose sub-soil support system. Tree Isles can be aesthetically implemented using permeable drainage strip around their CorTen steel walls.
