About Velliss Building
In Construction + Renovations
A family-owned Sydney building company with over 18 years of experience delivering quality residential and commercial construction across Sydney.
Our Story
Velliss Building was founded on a simple belief: that every client deserves honest communication, quality craftsmanship, and a builder they can trust. Over 18 years, we've grown from a small residential operation into a full-service construction company — but our values have never changed.
Led by Tas and Joanna Velliss, we've built our reputation project by project, suburb by suburb. From first floor additions in Earlwood to luxury renovations in the Eastern Suburbs, every job gets the same level of care and attention to detail.

The People Behind Velliss Building
Tas Velliss

Joanna Velliss

Joanna manages client relationships, project coordination, and the day-to-day running of the business. Her focus on communication means clients are always informed and confident throughout the build process.
Together, Tas and Joanna bring a personal touch to every project — you deal directly with the owners, not a salesperson.
