Thailand's real estate sector is shifting toward "wellness" and "longevity" housing targeting an aging population. The trend moves beyond senior-only communities to multi-generational, health-conscious homes using universal design principles—smaller units (50 sqm vs. 100 sqm), better ventilation, and lower floor bedrooms at accessible prices. With Thailand's population graying rapidly (20+ million people aging 60+ in the next 12 years) and global wellness economy projected to reach $8.9 trillion by 2029, developers see this as a new growth curve. Phuket and other locations position Thailand as a premium "longevity hub" for wealthy foreign retirees seeking safe, wellness-focused living.
