One team for the whole job.

Varloch Group is a Sydney building company started in 2020 by Nick Varley and Jan Lochtenberg. We design the house, build it and look after it afterwards.

Fewer hand-overs means fewer gaps. Our own builders and plumbers do the work, and a director is on site every week.

Design
In-house building design, drawn with the build in mind.
Construction
New homes, major renovations and additions.
Services
Plumbing, maintenance and care for homes we look after.
