HDB HandySearch — building self-reliance for home maintenance and repairs HDB HandySearch — wireframe iterations across diagnostic, contractor search, quote comparison, and payment flows

hdb handysearch

Building self-reliance for home maintenance and repairs. HDB needed to help homeowners find, vet, and hire contractors on their own terms — reducing call volume while improving trust. The result was a contractor marketplace with four core features: a diagnosis tool embedded with HDB's maintenance protocols, job request form and multi-quote comparison, contractor profiles with ratings and cost estimates, and direct chat, appointment booking, and payment. Wireframe iterations tested across three phases.
