Your Future. Built Better.

Live Better In A Passivhaus (Passive House):
The Sustainable Design Of The Future

Imagine a future where homes are not only free from mould and allergens, but also capable of maintaining a comfortable
temperature between 20-25 degrees all year round. Picture a world where homes use 90% less operational energy,
leading to nearly negligible heating and cooling bills, while also leaving a positive impact on the environment.

Community of People
Committed to the “Passive
House” Movement

Ever since the first Passivhaus (passive house) was built in Germany in
1991, a growing number of visionary builders & homeowners have decided
to change their approach to home design & construction.
With the passive house design process, you can be sure that your home
delivers maximum energy performance & the highest level of comfort
imaginable (including a constant, 20-25 degrees in temperature!) for the
building’s entire lifespan.
No more excessive heating or air conditioning costs—just a simple, efficient
technology that gives you a sleek design & efficient air circulation.

And let’s not overlook the unique health benefits of passive house building,
like reduced respiratory issues, thermal comfort, and better sleep patterns.
The meticulous sealing and advanced ventilation systems effectively filter out
pollutants, allergens, and contaminants–providing you with much fresher and
cleaner air to breathe!

The 5 Key Principles That
Make Passive Building the
Superior Choice For Creating
Your Ideal Forever Home…


Continuously Insulated Envelopes

Drastically reduce the usual amount of heat that’s lost with
conventional building methods. This increases thermal comfort
and reduces the risk of condensation (mould) in our buildings.


Airtight Construction

Reduces uncontrolled drafts that lead to discomfort, and energy loss.


High-Performance Windows

With double or triple glazing are well insulated and virtually
airtight. This helps maximise the energy efficiency while
reducing heat transfer through the windows that causes
excessive heating or cooling in the home.


Thermal Bridge Free Construction

Reduces the thermal pathways in your home that transfer
external temperatures through the insulated envelope into your
home. This allows us to maintain constant temperatures inside
the building regardless of the external temperature.


Heat Recovery Ventilation

Helps control internal air temperature at 20-25 degrees and
effortlessly bring fresh air into the home. This system reduces
pesky pollutants, odours, CO2, and controls humidity levels.

The result of these efforts?
Your passive house requires 90% less energy, maintains a comfortable 20-25 degrees
year round, and you can enjoy fresh allergen free air, all of which contribute to a
healthier, more fulfilling lifestyle.
