# Lifecycle Extension: Adaptive Reuse, Layering, and Open Building

Patterns that multiply a building's useful life through retrofit, conversion, and design for adaptability.

- [Adaptive Reuse](adaptive-reuse.md) — convert an existing building to a new use before accepting demolition and replacement.
- [Shearing Layers (Six S's)](shearing-layers.md) — separate building layers by their different rates of change.
- [Long Life, Loose Fit](long-life-loose.md) — make durable parts last while keeping shorter-life parts forgiving enough to change.
- [Open Building (Support and Infill)](support-infill-building.md) — separate long-lived support from occupant-controlled infill.
- [Adaptive-Reuse Feasibility Triage](adaptive-reuse-triage.md) — test reuse viability before the demolition or replacement path hardens.
