Sustainable building

Functional high-performance
design is our priority. 


What is a Passive House?

Layout of house maximizes solar exposure in the winter through smart window orientation, and provides shading in the summer with a carefully planned overhanging roof. 

Seamless insulation to achieve Passive certification and efficeint temperature regulation.

Triple glazed, Passive certified windows and doors can reduce heat losses by up to 70% compared to double glazed windows.

The Passive House Standard ensures a building is free from draughts, free from cold spots, and free from excessive overheating. Passive also provides a constant supply of fresh, clean air to the home.

A building standard that is truly energy-efficient, comfortable, affordable, and ecological at the same time. Passive House is not a brand name, but a construction concept that can be applied by anyone and one that has stood the test of practice.

Essentially, a passive house is designed to be extremely energy-efficient so that it doesn’t take a lot of power input to heat or cool. To be designated as a passive house, a building must embody a set of specific best practices that seal it from outside temperatures while maintaining a stable inside temperature and a high indoor air quality metric.


Our processes are intentional.  

environmental stewardship

The health of occupants within our buildings is supported by the health of the natural environment. We elect to work with products and companies that have a strong ethos for:

  • environmental stewardship

  • positive bio-feedback loops

  • zero waste facilities


The best of the best. 
Materials to last.

Carefully selected building materials with low pollutant emission profiles are the preference at Tree.


A focus on wood construction assemblies - including our insulation and an air-tight construction - are the complete solution for our passive houses. With perfect heat retention free from harmful substances, a naturally healthy home is achieved. Technology combined with ecological construction effectively contributes to a better quality of life.


Efficient building just makes sense. 
Simple as that.

Following simplified techniques and passive certifiable construction assemblies, the trifecta of Tree culminates with attention to detail and quality.


This quality is controlled through a careful apprenticeship program and training, along with long-term mentoring. Monitoring and managing all aspects of a project while utilizing our network of suppliers and trades maintains heightened attention to detail.

The air you breathe
and the chemicals in your house.

A healthy home is the foundation to a happy life. Holistic thinking and constantly innovating, our aim to have a 100% healthy home that can be air quality tested. The people at Tree know they cannot instantly change the world but want to make it better. Inhale, exhale, and enjoy life.


Design layout with
sustainability in mind.

Functionality, accessibility, and aesthetics: we're always using these design principles to create efficient use of space. Our floor plans are simple and effective in minimizing waste and maximizing comfort. We incorporate natural light as much as possible. Interior layouts and architecture go hand-in-hand with building orientation and window placement to maximize solar gains in the winter and avoid overheating in the summer.
