Our Mission

Future-Proofing Hong Kong's Homes

Homegevity™ exists to reposition the practice of Dai Wai Sau (大維修) — the costly, disruptive, uneconomical, and enviromentally-unfriendly full-building renovation overhaul paradigm that threatens the safety, finances, and quality of life of hundreds of thousands of Hong Kong homeowners. Dai Wai Sau is necessary for the aged developments that have already missed their window of opportunity. For the younger residential developments, now is the opportunity to pivot to take advantage of the pioneering success proven in 2026 in Hong Kong.

Through the Homegevity™ model — pioneered and succesfully validated through five years of innovation and live application — we have demonstrated that the threat is avoidable. Homegevity™ is the vehicle that can be scaled across Hong Kong, and ultimately to every high-density residential city in the world.

The name says it all: Home longevity. Buildings that last. Homes that hold their value. Communities that thrive.

Building maintenance and renewal at scale

What We Stand For

Three Principles

🏠

Owners First

Every recommendation, every innovation, and every policy proposal is evaluated through a single lens: does it create measurable, lasting value for the homeowner? The interests of the supply chain are secondary.

📊

Evidence-Led

Claims without data are opinions. Every figure published by Homegevity™ is sourced, auditable, and conservative. The Bel-Air case study is the gold standard: real numbers, real buildings, real outcomes.

🌏

City-Wide Mission

Success in one of the city's most sophisticated residential estates is good news to all residential developments in Hong Kong. Every private residential building in Hong Kong is the mission. Every high-density city in Asia Pacific is the opportunity. Homegevity™ thinks at city scale from day one.

The Founder

Ha Wing On Allen, MH

🏅 Medal of Honour (MH) — Hong Kong SAR Government

🏢 Founder — Homegevity™

🌏 Regional Large Scale Development Management — 30+ years, Asia Pacific

Ha Wing On Allen, MH is a real-estate veteran of world-class mega-property development and management with over three decades of experience across Asia Pacific's most complex property markets. A recipient of the Hong Kong SAR Government's Medal of Honour, Allen has spent the past five years innovating and applying that expertise to one of Hong Kong's most urgent — and least-discussed — challenges: the structural and systemic challenge of the city's residential building maintenance paradigm, culminating in his five years of intensive development and three years of real-life application of Homegevity™ at Bel-Air, demonstrating success and tremendous value created.

The catalyst was a HK$1.057 billion Dai Wai Sau proposal for Bel-Air, Pokfulam — one of Hong Kong's flagship private residential developments, home to 2,775 families. Rather than accept it as inevitable, Allen was entrusted by fellow owners to lead a team of innovators and domain experts, and successfully applied Homegevity™ to eliminate the Dai Wai Sau requirement and created over HK$1 billion in validated value for homeowners.

This pioneering success is the subject of the short-form lecture series, research publication, and policy advocacy platform presented on this site.

Allen's vision extends beyond Hong Kong. High-density residential aging is a universal challenge across Asia Pacific and beyond. The city that solves it first will become the global hub for a new PropTech and Homegevity™ ecosystem.
