About us

Top-quality, sustainable and healthy homes for Australians, at an affordable price

The Passivhaus Design & Construct group brings expert architects and interior designers together with experienced building teams. We’re a group of companies each with successful track records and reputations, focusing our talents together to deliver affordable, sustainable homes that are energy-efficient and healthy.

Passivhaus Design & Construct is the brainchild of the architects that head up Envirotecture, an architecture and interior design company founded in 1995. The company is an award-winning leader in deeply sustainable, healthy home design.

Andy Marlow

"The high cost of building is putting healthy, comfortable new homes out of reach of too many Australians. The team at Envirotecture brought together builders we trust to develop ways to make Passivhaus levels of performance affordable. We’re offering flexible, innovative options to suit a wide range of people.

"We’re offering an alternative to low-quality volume builds with vague pricing—and the complexity, long timeframes and cost of a bespoke architecturally-designed home."

— Andy Marlow, architect, Envirotecture and Passivhaus Design & Construct director

I chose Envirotecture because they are a leading sustainable design firm and one of the few architectural practices with experience designing and building Passivhaus buildings in Sydney. Choosing a designer with Passivhaus experience gave me a lot of confidence that I wasn’t going to be paying for their learning curve or risk making costly mistakes along the way. And that’s how it turned out.”
— Chris Nunn, owner of PurePassiv, designed by Envirotecture in 2021
Garrett Clarke
“Passivhaus is a really smart way of building. The benefits to the client are fantastic, and from a construction point of view, it’s very satisfying. We build people’s private homes, where they live and raise their families: it can never be ‘just a job.’ It has to be just right.”
— Garrett Clarke, Red Cedar Construction
Dave Selby
“Building a great home requires organisation, communication and a great team. I love watching clients’ excitement as we work through the design and build.”
— Dave Selby, IMAC Developments
Jamie Graziano, Builder
“I want my legacy to be a good one: quality homes that are good for people and that last. After 20 years of building, I still get a kick out of seeing my customers happy and knowing I’ve done a really good job.”
—Jamie Graziano, Superior Construction
