Services we
  • Sustainable Building Design - efficient, low carbon, durable, resilient, adaptable, livable - tangents of our designs
  • Energy Efficient - our personal goal is 8star Renovations, 9star New Builds
  • Low Carbon - material choices have an impact on the environment, and we like to consider where they come from and how they are made
  • Adaptable - you spend your life paying off your home; why make it only suitable for your needs and desires of today?



Based in South East Queensland, we work on renovations and extensions on housing from the 1880s to the 2020s, deep energy retrofits as well as off-grid/hybrid new home designs.

My goal is to design homes that you are proud to live in, with features that are livable rather than visual, that future generations can respect.

Esther James is 4305 Design’s Building Designer. 

Her job is to guide you through the process of finding out what you can achieve with the available construction budget, designing the best possible scenario for your scope of work, delivering a comprehensive set of detailed construction drawings, identifying the legal requirements for your project, and whose services you need to engage to move from concept idea to approved plans. 

Esther’s extracurricular activities include researching emerging approaches to sustainability in residential construction. She is an advocate of the building design profession, mentors building design students and is a member and volunteer with the Building Designers Association of Australia, working towards using the built environment as a solution to climate change.
