A sealed, breathable envelope
Every external wall and roof plane is wrapped in a Proclima membrane, every join, lap, penetration and window reveal taped into one continuous air and weather barrier.

Builder, Leichhardt NSW
Homes built well beyond the code.
Avern builds new homes, duplexes and additions across Sydney with a sealed Proclima envelope, LVL framing and double glazed, thermally broken windows on every project.
About Avern
Founded in Leichhardt in 2021 by Adrian Verde.
Adrian started Avern at 25 to build high quality homes backed by trust, transparency and strong relationships. It has grown through word of mouth and repeat clients.
Construction can be complex. Organised systems, clear processes and efficient delivery keep it simple for our clients, from the first conversation to handover and beyond.
The Avern standard
Six things we do above the building code.
High performance construction is our standard on every project, not an upgrade.
Concrete subfloors, not particleboard
Where a home is not on a slab we lay AlphaFloor 35 mm precast concrete panels. Rain on site cannot swell them, and they add thermal mass and quiet.
Learn moreStraight LVL wall framing
LVL replaces standard MGP pine in every wall frame. It stays straight and plumb, so the membrane and insulation stay continuous.
Learn moreDouble glazed, thermally broken windows
Our minimum on every project. We push for uPVC or timber frames, which do not run hot and cold the way aluminium does.
Learn moreInsulation above the code
Thick batts in every external wall and roof cavity, with a VRV system keeping fresh, filtered air moving through the home.
Solar proposed as standard
Panels, and a battery where it suits, to cut power bills and reliance on the grid for the life of the home.
What we build

Our philosophy
Built to be enjoyed for generations.
Our philosophy is simple. Construct buildings that stand the test of time and last a lifetime, built to be enjoyed for generations to come.
We take genuine pride in every project we deliver, and we are committed to continually improving how we build.
A home built well beyond the minimum National Construction Code. It is airtight, well insulated and well glazed, so it holds a steady temperature, uses less energy, stays quieter and keeps moisture out of its structure.
Proclima membranes on every wall and roof, AlphaFloor concrete subfloors where there is no slab, LVL wall framing, double glazed thermally broken windows and insulation above the code, with solar proposed as standard.
