The people behind every project
Inzterior operates under the registered business Istory Design Studio (SSM Reg. No. SA0647003-M), based in Horizon Hills, Iskandar Puteri. Every project is led by a single point of contact, backed by a vetted network of contractors and tradespeople.
Billy Yeap
Founder & Principal DesignerBilly started Inzterior to fix the trust problem he kept seeing in Malaysia's renovation industry — deposit-and-disappear contractors, vague scopes, and designers who were never properly registered. He leads every project's design direction and stays as the client's single point of contact from concept to handover.
Jackie Yap
Co-founderJackie co-founded Inzterior alongside Billy, bringing the same commitment to transparent, well-documented renovation projects across Iskandar Puteri and Johor Bahru.
A small team, a clear process

Space planning, mood boards, and material selection tailored to how you actually live — not a template pulled off the shelf.
Project Management
One point of contact coordinates contractors, timelines, and milestone payments so nothing falls through the cracks.
Site Execution
A vetted network of contractors and tradespeople carries out the work, with progress documented in photos and video at every stage.
