Preserving a large tree can dramatically change a building's design.
Foundations must be altered to avoid damaging roots, balconies and roofs may need openings cut through them, and engineers must account for future tree growth, movement, and maintenance.
A mature tree provides benefits that cannot be replaced quickly by planting a new sapling.
Large trees can lower surrounding temperatures, improve air quality, reduce erosion, absorb stormwater, and provide habitat for birds and insects. Some take decades or even centuries to reach their full size.
Building around a tree is often more expensive and complicated than cutting it down. It requires ongoing monitoring to ensure neither the structure nor the tree harms the other over time.
