Torren Bell Building Design is an award-winning building design company with a strong background in single, multi-dwelling residential and commercial projects. At the heart of the practice is a commitment to quality, form and function – a philosophy that has earned designer Torren Bell an ever-increasing base of clients attracted to the unique liveability and beauty of his design.

The practice was established in 1996 and over the past 20 years has designed custom buildings across Australia. We offer a number of services throughout the design and construction process, including building design, detailed documentation, liaison with relevant councils and other authorities, interior design and finish selection.

In practice, building sustainability means living in harmony with the natural environment, considering the social, environmental and economic aspects of decisions, and reducing our footprint through a less energy, water and material intensive lifestyle. Social sustainability is also important and working towards a healthy and safe community is often interconnected with economic and environmental endeavours.
