What Decode Group does
Decode Group Pty Ltd is a privately held, Sydney-headquartered construction services company founded in 2008 by Sam El Rihani. Operating across the full spectrum of the construction sector, Decode delivers integrated design, construction, delivery, and post-construction services for residential, commercial, mixed-use, seniors living, student accommodation, and affordable housing developments—primarily across New South Wales, Australia, with activity in Sydney, Newcastle, Castle Hill, and surrounding regions. The company's service model is built on a collaborative contracting approach that shares risk and reward with developer clients, supported by ISO 9001, ISO 14001, and ISO 45001-certified management systems and an integrated digital safety platform (HammerTech).
Decode generates revenue through project-based construction contracts—fixed-price, design-and-construct (D&C), construction management, and lump-sum arrangements—won primarily through competitive tendering and Early Contractor Involvement (ECI) engagements with property developers, government and institutional clients, and aged-care providers. Documented scale includes more than 50 projects delivered, approximately $1.7B in value delivered to date, a $1.4B active pipeline as of late 2025, 17 active developments, and over 2,500 homes underway. Notable clients span institutional and private developers including Sekisui House Australia, Nuveen, Ellipse Property, Thirdi Group, WINIM, Austino Properties, Sammut Group, Anglicare Sydney, and Link Wentworth. The firm reports a 67% repeat client rate and holds a 4-Star iCIRT rating (Equifax Australia), along with NSW #1 Residential Builder recognition from Master Builders Australia 2025.
Decode operates through wholly-owned subsidiaries including Decode Construction (core delivery), Ellipse Development (development services), and Ellipse Property (property development). Leadership includes Founder & Chairman Sam El Rihani, CEO Divya Mehta (appointed early 2024 from the Managing Director role at Decode Construction), Group Director Hamze El Rihani, and a senior team combining civil engineers, licensed builders, quantity surveyors, and HSEQ professionals. The company is privately held with no disclosed institutional investors, no parent company, and no recurring funding rounds identified in source material.
