Our Story

30+ Years Building Experience

Optam Building Group is led by director and registered builder Royce Beale, who started as a carpenter in 1995 before moving into building management. Since then, the business has grown almost entirely through word of mouth and repeat work — a track record built on honest advice, quality construction, and staying involved from the first phone call through to handover.

Our preferred client is building a $1m–$2m high-end, luxury or executive-style home they intend to live in and enjoy for decades — including rural lifestyle homes, knockdown rebuilds and difficult, sloping-site builds most builders shy away from.
