This subject introduces students to the concept of academic literacy in a higher educational context. Students will be able to study the relevant resources and explore strategies and techniques which will allow full participation in their new academic environment. The course will provide students with research skills (information literacy), critical analysis, writing and language techniques. Transferable skills including time management and teamwork are incorporated in the course. The aim of this subject is to provide knowledge and skills needed for Higher Education, to help students to manage their own success and to assist students in reaching their academic potential.

This subject is an introduction to the design process and its application to interior decorating and design. The student learns about design principles and elements and their place in the creative design process. Producing design concepts for an interior space through a series of exercises using creative thinking methods, e.g. brainstorming, trigger word, etc., the student uses experimentation to explore and challenge a range of different ideas. The production of sample boards and presentation boards is explored. During this subject the student acquires a basic understanding of sustainability, environmental hazards/risks, resource use and inefficiencies associated with the interior design workplace and apply those principles to the design studio environment.

Drawing is a rudimentary and essential basis for any design career. This subject introduces the student to the methods and techniques of basic photo imaging and drawing and professional visualisation in the context of interior design. Students explore a range of techniques and materials and their application in order to communicate design concepts and assist students in understanding the principles of design and their specific application to drawing. Both manual and digital methods of visual communication are explored.

In this subject the student learns how to develop and refine a range of techniques to produce technical and concept drawings. The student explores the way design drawing, both technical and concept, can be applied to interior decoration and design contexts where visual representation is required. The student learns how to produce floor plans, elevations, sections, isometric, and axonometric drawings relevant to interior spaces and furniture.
Both manual and digital methods and techniques are explored.

This subject investigates the evolution of interior design. It explores major art and architectural movements throughout history and the development of contemporary design and interior design by investigating significant turning points and historic milestones. This subject will focus on developing the students’ understanding of the complexities of designing an area (e.g. bathing, sleeping, food preparation, reception desk, workspace etc.) within a spatial environment whilst identifying and incorporating sustainable design practice – not only in materials and technologies but also in the longevity and adaptability of the final design solution. Students will integrate their research and knowledge of environments, identifying design related and environmental imperatives in the realisation of design briefs.

This subject introduces the student to research and specification of furniture, soft furnishings and accessories for interior spaces. The student learns how to interpret the decoration requirements from a project brief, research furniture and accessories and make the appropriate recommendations to the client. The student also learns how to assess soft furnishing requirements, research soft furnishing materials, window treatments, and soft floor coverings. The student is introduced to the application of Australian Standards, documentation and presentation of decorative recommendations.

In this subject the student learns how to identify the different types and features of hard materials and the hard material requirements for a project. The student carried out research on various hard materials and finishes and documents the recommendations for the client. The student furthers their knowledge of the Australian Standards and regulations and codes. The sustainability of a design is assessed and the student learns how to apply resources sustainably.

In this subject knowledge of structural components and systems is developed and the student learns how to interpret plans and specifications for interior projects. The student is introduced to legislative regulations, codes and standards and their application in residential design. This subject introduces the student to industry standard CAD software and its application. The student will learn how to set up CAD drawings, create and edit objects, add text and dimensions to drawings and plot or print drawings.

In this subject the student learns how to evaluate materials and construction methods used on a site in order to determine their impact on the interior design brief. The student will also learn how to manipulate 3D interior space and form applying the elements and principles of design in response to a brief. A project evaluation will be carried out by the student and they learn how to design the structural elements and the construction aspects of a design. They learn how to liaise with specialist professionals and prepare design documentation for a commercial project.

Within a commercial context, the student learns how to analyse the project brief, conduct project research, generate decorative themes and concepts, select and specify internal finishes, furniture, furnishings, lighting and object d’art. For this subject the student will present a fully resolved scheme and evaluate the client response.

This subject includes the development of the students own voice through exploring and experimenting with new ideas in making and/or interpreting work. The student will develop acquired skills, develop conceptual skills and ideas, evaluate their own work and research work opportunities. The student consolidates their knowledge of the design industry, design as a profession and the relationship between design and other industries.

The student applies industry knowledge to work activities, maximising effective performance and also gains knowledge of ways to maintain currency in design industry trends and practice.

The Work Integrated Learning subject is a core requirement of both Diploma (3rd Trimester of Diploma) and Degree students (4 th-6th Trimester of Degree). Degree students who have completed WIL at Diploma level will be considered as having fulfilled the requirement.

External Placement: offers students the opportunity to work within a professional design studio for an extended period of time. It encourages students to build long-term relationships with the design industry and exposes them to the rigour of applied design practice while building their confidence in adapting to new environments. It also provides a context in which to enhance their communication skills and work collaboratively in a professional arena.

Externally placed students will be matched to an appropriate mentor at the placement site and monitored by an academic in the discipline of study.

Internal Placement: students will engage with a similar range of professional experiences to those placed externally. Assignment to, and management of, WIL tasks may occur face to face or via a dedicated online platform managed as an extension of the Billy Blue Studio (subject to renaming).

Internally placed students will be directed by a project leader appointed within the Billy Blue Studio and monitored by an academic.

In both cases:

  • projects may vary in length
  • may be individual or group based
  • students may or may not see projects through to completion but may contribute to (and be assessed on) progress
  • students may be involved in the initial pitch to clients and/or supervisors for the awarding of the project
  • students may, or may not, be involved in presenting the project during its progress, or at completion
