With a passion for environmental preservation and multiple sustainability awards, Croft Wootton Construction is your go-to eco-home builder on the Mornington Peninsula. Whether you’re doing sustainable home renovations or building a green home from the ground up, we’ll get the job done right with minimal environmental impact.
Our founder, Nick Wootton, has a special interest in passive house and green living principles and draws on decades of real-world expertise. From sourcing recycled materials to reducing on-site waste, we put the environment at the forefront throughout your build. Our advanced, eco-friendly, and green home design and construction techniques optimise energy efficiency so you can enjoy a cleaner, greener lifestyle for years to come.
As a passionate passive house builder, Nick leads the team in adopting these principles to reduce your energy expenditure. Some of our tricks of the trade include maximising wall insulation, installing double-u PVC-glazed windows, and constructing internal concrete walls to create thermal mass. In a previous project, we pulled off a 10++ star rating to create a comfortable 18-20C year-round temperature without any heating or cooling.
Of course, even the most energy-efficient homes still require some electricity. We offer premium Photovoltaic Solar Systems with high-capacity battery storage to complement your passive house home. This potent combination of solar and passive house principles has allowed some previous projects to achieve Zero-Energy Building (ZEB) status.







Nick has in-depth experience with Green Living building techniques and shares his knowledge with the team. Wherever possible, we use recycled materials sourced on-site or from the local area. Failing that, our team finds renewable, sustainable, or low-impact construction materials to minimise our carbon footprint.
Other green living techniques we adopt include water harvesting solutions, efficient appliances and fixtures, and drought-resistant landscaping. We also specialise in rammed earth construction, an eco-friendly building technique dating back thousands of years.
We can incorporate the most effective passive house principles to optimise energy efficiency in your home, potentially creating a comfortable year-round temperature without heating or coolin
Our comprehensive experience in the green living construction industry lets us minimise our environmental impact with every build.
Don’t just take our word for it. Check out our previous MBAV awards for Best Sustainable Homes.
We primarily use skilled full-time employees instead of subbies to guarantee quality and consistency. As eco-friendly house builders, they are masters of their respective trades.
We’re the most hassle-free sustainable home builder on the Mornington Peninsula. Transparent communication, clear costings, and regular updates put you in control of the process.
We’re a friendly bunch and always treat your residence with utmost respect. Many previous clients have told us they miss having the team on site.
Call us today for a no-obligation discussion with Nick to get the ball rolling on your dream green home.
A Passive House is a building designed and built according to strict energy efficiency standards, aiming to minimise energy consumption for heating and cooling. In effect your home should stay at a stable temperature 24/7 with no mechanical heating and cooling.
By using super-insulated walls and roofs, airtight construction, high-performance windows, and heat recovery ventilation, a Passive House drastically reduces the amount of energy needed for heating and cooling and makes the best use of the sun's energy.
Passive Houses offer significant energy savings, improved comfort, and better indoor air quality. They are also durable and require less maintenance.
While the initial cost may be higher than conventional construction, the long-term savings on energy bills and potential for tax incentives can offset the initial investment.
Conventional homes are typically less efficient and rely heavily on heating and cooling systems, leading to higher energy bills and environmental impact. Passive Houses minimise these needs through design and construction.
Yes, Passive Houses utilise materials that are high in insulation and airtightness, such as specialised insulation and high-performance windows.
No, Passive Houses are designed with a heat recovery ventilation system that provides fresh, filtered air while removing stale air, ensuring good indoor air quality.
Yes, you can open windows in a Passive House, although it's not necessary for ventilation due to the heat recovery ventilation system.
An airtight envelope is a barrier that prevents air leakage into and out of the building, minimising heat loss and gain.
Thermal bridges are areas in a building's structure where heat can escape more easily, such as poorly insulated windows or doors.
Heat recovery ventilation systems extract heat from exhaust air and transfer it to incoming fresh air, reducing energy consumption for heating.
Insulation helps to regulate temperature, preventing heat from escaping in the winter and keeping the house cool in the summer.
It's recommended to work with professionals who understand Passive House principles and standards.
Passive Houses tend to have a higher resale value due to their energy efficiency and comfort.
