Cantilevered balcony/slab: thermal bridge, condensation and corrosion
A slab or steel element crossing the envelope can chill interior surfaces and concentrate water, salts and corrosion at the interface.
Triage only — not a design.

These links connect this page to the next useful checks and decisions without repeating the full content.
Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
Advanced diagnostics to cross-check
V16 connects water, soil, climate, safety, materials and seasonal use to existing projects.
Specialized diagnostics to verify
V18 connects systems that become costly or regulated when a primary project triggers them.
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
Project risks and overlooked interfaces
V27 connects payment, water, envelope, ventilation and jobsite details that often create costly surprises.
Commissioning and everyday safety
V31 helps verify systems after work and document the values that make a home safer to operate.
Use, excavation and construction constraints
V34 connects use permits, soil, excavation, neighbouring structures and public-space logistics before hard-to-reverse work.
V47 interfaces not to miss
These details are small on a drawing but can control water, structure or durability.
