OTTONWOOD GROUP has finalized a $105 million senior construction loan to build a 223,500‑sq‑ft life‑sciences complex at 3600 Breakthrough Loop in EastVillage, a 425‑acre innovation district in northeast Austin. The site is fully pre‑leased to BillionToOne, a molecular‑diagnostics firm focused on non‑invasive prenatal and oncology testing. The project is a joint effort between Reger Holdings and Tarlton Properties, a Bay‑Area developer known for life‑sciences projects.

    Mark Green, Cottonwood’s CIO, said the deal stood out after extensive market analysis, citing the tenant’s critical need, seasoned partners, and Austin’s steady demand. John Tarlton, CEO of Tarlton Properties, praised Cottonwood’s flexible financing approach, which enabled the tenant’s tight schedule.

    The new facility will support BillionToOne’s expansion and create roughly 1,000 jobs. It follows Cottonwood’s $284 million bridge loan that recapitalized key EastVillage assets last year. Gordon Reger, Co‑Founder of Reger Holdings, highlighted the project’s role in cementing Austin as a life‑sciences hub and advancing EastVillage’s long‑term vision.
