Booth House, Philip Johnson’s first residential commission, thoughtfully restored by R&D as a modernist retreat in the woods of Bedford, New York — for those who value mid-century history, natural light, and timeless design.

R&D is a design-led development firm founded in 2026 by builder Ravi Arps and architect Drew Lang.

Focused on architecturally significant restorations and original residential projects, R&D brings design and delivery under one accountable standard — from concept through construction, sourcing, and final details.

Our pipeline is intentionally small, with each project guided by material integrity, a strong relationship to landscape, and the belief that design should shape and enhance daily life.
