VCD YEAR 10 AOS 2
Design a cool
Tiny house.
How can living small save the planet quicker?
In this task, students will use the Define, Develop, and Deliver stages of the Design Process to understand audiences and users and to develop and resolve design solutions for a Tiny House using manual and digital-based methods. They will investigate users and their housing needs and use that information to inform the development of design ideas. They will learn how to document design concepts using the conventions for environmental design in two-dimensional drawings. Students will learn how designers deliver design solutions using two- and three-dimensional methods. They will practice divergent thinking to develop ideas and convergent thinking to select, resolve, and evaluate design concepts and solutions.

VCD Design process
The VCD design process is a framework that illustrates the process designers use. It is based on a model conceived by the UK Design Council in 2003. There are four stages to the VCD Double Diamond design process. Discover, Define, Develop and Deliver. Each uses different kinds of thinking. Sometimes designers need to think outside the box. Thinking outwards is called Divergent Thinking. At other times, they are trying to narrow and refine their ideas. This is called Convergent Thinking. The design process structures everything a designer does, from generating their first inspiration to delivering a design solution to their client.
Areas of study in Target Learning VCD emphasise different stages of the VCD Design process.

The VCD Double Diamond design process. Note the positions of Divergent and Convergent thinking.

Solving the housing crisis
In this section, students will explore and gain insight into the housing needs of contemporary audiences and users. They will learn how understanding audiences’ and users’ needs and requirements informs the writing of a communication need. They will also research various existing designs and regulations for towing trailers.

Discover
Use Divergent Thinking to challenge assumptions and explore design problems and opportunities.


Define
Use Convergent Thinking to analyse, evaluate and present information for Human-Centred design.

Background
The current ‘housing crisis’ is caused by several factors. These include Australians’ preference for large blocks of land with enormous houses known as ‘McMansions’. These dwellings are expensive to construct and use excessive amounts of land and resources for building, heating, and cooling. Expanding the already sprawling suburbs is simply unsustainable.
One way to contribute to solving this crisis of unsustainable unaffordability in housing is to build relocatable tiny houses. These frequently ‘off-grid’ housing solutions offer all the space and comfort a couple needs without consuming large areas of land. They can be adapted for permanent, transient, or temporary accommodation. This task will explore the benefits of tiny houses.
The Tiny House
A tiny house is a small, often relocatable housing solution. They often incorporate environmentally sustainable features such as off-grid electricity and water collection systems. They provide an alternative to the ongoing consumption of land and resources caused by endless urban expansion in new suburbs, which suits a more minimal lifestyle. Tiny houses use less land and material than traditional housing. They can help address Australia’s housing crisis. This task will explore the benefits and design of tiny houses.

Needs, constraints and expectations
Tiny houses are full of features that their owners prefer. Features or specifications for designs are known as 'constraints'. Some of these are physical features, others are features for sustainability and lifestyle. These are the expectations users have about their homes.
Here are some links where we can find out about Australia’s best tiny houses:
Defining a communication need
A communication need is an open-ended statement that outlines what a designer is required to do. However, it does not specify what a design solution looks like. It is deliberately open-ended to allow a designer to work creatively. Here’s an example communication need for this task:

Develop design ideas
In this section, students start to resolve design concepts. They learn how to present their ideas in a collaborative design critique and provide constructive feedback to their peers. They evaluate and select design concepts for resolution and documentation.

Develop
Use Divergent Thinking to challenge assumptions, test and explore ideas with unexpected results.
Visualise design ideas
When designing a new product, designers start by creating numerous sketches. Remember, the objective of the Develop stage is to think divergently. That is, creatively and without limits. In this stage, students will produce A3 pages filled with drawings of potential ideas for a tiny house. They will utilise line techniques through the manual method of freehand sketching. Some visualisation sketches are shown below.

Select and resolve design concepts
The next step in the Develop phase is for student to evaluate their work and select the concepts that might be best to refine. ‘Refine’ in VCD, means to improve.
We will use a mini critique method to help get feedback and select the ideas that might best suit our users’ requirements and address the communication need. After students have selected their best ideas, they will start improving them in more formal drawings using colour to represent materials.

Development of concepts includes beginning to use conventions for environmental design. Ariella Rivo.

Identify, describe and evaluate
As students develop their drawings, they need to reflect on their successes and identify areas for improvement. Students record their reflective (convergent) thinking by writing annotations beside their drawings. They should identify the features, design elements, and materials they have experimented with. They should also evaluate the effectiveness of their designs.

Document Design Concepts
In this section, students learn the conventions that environmental designers use for formal two-dimensional drawings to communicate information to clients and building practitioners. They learn about the concept of scale and practice creating correctly proportioned views of form and space at different sizes. They learn about the actual sizes of objects used in homes and how to draw them accurately in the scales they will use. Students conclude this stage by creating manual two-dimensional drawings of their selected Tiny House.
Two-dimensional drawings: Plans and elevations

Completed plans and elevations for a Tiny House at a scale of 1:50 on an A2 sheet.


Environmental designers, such as architects, use a special kind of two-dimensional drawing to depict information about buildings and environments for their clients. These kinds of drawings use conventions (rules) for how they are drawn and to enable them to be read accurately. Conventions include aspects such as views, scales, symbols, dimensions and labels. We will learn how to incorporate them in our drawings.
The drawing above shows a completed drawing for this task. Let’s work out how to get from freehand sketches to here.
Scale
Before we start resolving (improving and perfecting) our design, we need to understand how big things in a tiny house are in real life, and how big we should draw them on a sheet of paper. Consider the following information:
A tiny house typically measures about 6 m in length and approximately 2.5 m in width. This size will not fit onto a piece of paper; we will have to draw it smaller than its real-life dimensions. Environmental designers utilise a scale to maintain proportionality when creating designs on paper. Builders comprehend ‘scale’ when interpreting a drawing. A scale is represented as follows:
- 1:50
This is said ‘one to fifty’. It means the drawing (1) is shown fifty (50) times smaller than the real thing. Environmental designers use several different scales, including:
- 1:100
- 1:50
- 1:20
- 1:10
Scale table
Let’s explore how large we should make things at 1:50. This means we will divide the real size by 50 to determine the size on the drawing. I have created a list of items and their sizes in real life. Fill in the sizes in the table at 1:50. Oh, and by the way, architects use millimetres, not centimetres.

Measurement can be quite challenging, especially if students have little prior experience. Let's try a couple of exercises to help students become more familiar with it.
5.1 How big is 'how big is it'?
Imagine some dimensions, such as 50, 200, 600, and 450 millimetres. Use your hands to visualise these sizes. Have a partner check your estimates. Familiarise yourself with how these sizes appear.
5.2 How big is it in scale?
Here, it gets more difficult. In this task, we are working at 1:50. Practice converting all the sizes we tried above to 1:50. How do we do it quickly? Simply divide the number by 100, then double the answer. Try some numbers now and write them down.
5.3 How big does it look on the page?
Now, measure and draw three rectangles at a scale of 1:50. The sizes you need to create are 1 m x 2 m, 2 m x 4 m, and 6 m x 2.5 m in real life. Draw them at the scale of 1:50.

Resolving our design
Plans
Now that students have an idea of how big a tiny house and its contents are, when drawn at 1:50 scale, they are ready to resolve their initial ideas. In the task below, students draw a ruled plan of their tiny house at scale. This might not be their very final design, but by using the scale, they will become closer to drawing things in proportion.

Elevations
An elevation is like a side or end view of a building. Elevations also follow conventions in how they are drawn. They can portray the outside (exterior), the inside (interior), or depict a slice through (section) of a house. Elevations provide information about what things look like when viewed from one point in two dimensions. They are dimensioned in the same way as Plans. When drawing elevations, one must be mindful that lines shown in one plane coincide with the same lines in the Plan view.

Note: how to draw an elevation by extending lines from a plan.

CAUTION

Good to know
Paraline and perspective drawing
The paraline planometric and the two-point perspective methods are fantastic ways for students to learn how to represent the form of their tiny-house designs. Students will be required to use these methods in VCE Units 1 and 2 VCD, so it is preferable to introduce them to these systems during Years 9 and 10. However, they can be complex methods for teachers to teach and for students to learn and demonstrate. Target Learning recommends that teachers use their judgment regarding the level of independence they expect from their students in the following tasks. In some circumstances, it may be sufficient for students to reproduce a drawing,
Planometric Drawing
Drawing Plans and Elevations in two dimensions are a good way to ensure that a building is made exactly as it is designed, but it isn’t such a great way for a designer to communicate the look of a building to a client. The best way for to show their client is with a realistic, three-dimensional drawing. One easy method of drawing in three-dimensions is called ‘planometric’ drawing. It is easy to do and using a 45/ 45 degree set square allows people to keep things in proportion as they can measure along the sides of their drawing with real measurements. The drawing below is a planometric drawing of the Tiny House designed in this assignment. A planometric drawing can be easily done manually or digitally, on Adobe Illustrator ®.
For further information on planometric drawing, visit the page linked below.

Planometric drawing of the exterior of Tiny House

Process
Students should follow these steps to draw a planometric drawing of the exterior of their Tiny House using a 45/ 45 degree set square:
- Draw a V shape near the bottom of your paper using both sides of your set square
- Draw the plan of your Tiny House, rotated at 45 degrees. Draw it at the same scale as your plan. Don’t draw the interior details. You don’t need them for an exterior view
- Raise vertical lines about 100 mm from each corner of your drawing
- Turn to the Elevation you drew and measure the heights of walls
- Measure up the vertical lines from each corner and mark the tops of the walls
- Join the points at the top of each wall
- Add details like windows and doors
- Add 3D details like the inside of window and door frames
Here is a step by step video of how to construct a Planometric drawing with a manual method. You can also find it on the Planometric page, linked below.
One-point perspective
Perspective drawing is used to give a more natural representation of form. One-point perspective is often used for interior views. Teachers may find they need to spend some time introducing and teaching the fundamental knowledge and skills for one-point perspective before their students can undertake the task of drawing an exterior view of their tiny house. Information on one-point perspective can be found on the page linked below.
Manual method
Use a pencil, rulers and paper to construct a two-point perspective drawing of your tiny house.
For further information on one-point perspective, visit the page linked below.
Digital method
As an extension exercise, teachers may instruct their students to use Adobe Illustrator ® or an equivalent digital media to construct a one-point perspective of their tiny house. As a guide, students can follow the steps below to complete their drawing. It is easier than it looks.

Note how there are three kinds of lines in a one-point perspective view: vertical and horizontal lines (shown blue) and receding lines (shown red). The receding lines converge (meet) at one point, directly in front of the observer. This point is the vanishing point.

Step 1: Prepare a plan and elevation of your tiny house.

Step 2: Create a rectangle the same proportions as your elevation.

Step 3: Determine the position for the vanishing point. This does not have to be in the middle and it is at a natural height for an observer.

Step 4: Project (draw) lines from all of the corners of the features in the elevation back to the vanishing point.

Step 5: Estimate a size for your back wall.

Step 6:Divide your plan into quarters using diagonal lines.

Step 7:Divide the floor of your perspective using the same method.

Step 8:Project points for the width of each object back to the vanishing point.

Step 9: Referring to your plan, determine the depths for each object.

Step 10: Determine the height of your first object by finding a top corner on the elevation, then project it to the nearest wall, then project the height back to the vanishing point then to the rear of the object.

Step 11: Project lines upwards from the corners of your first object.

Step 12: Project lines forward from the vanishing point, through the top corners on your object to define its height.

Step 13: Determine the front of the object.

Step 14: Clarify the object.

Step 15: Establish the height and width of your next object. I am doing the kitchen unit on the right. Project a line back to the vanishing point from the height at the front on the elevation and the bottom corner.

Step 16: Rise lines from the corners of your object you have found by projecting lines to the vanishing point.

Step 17: Establish the top of the object.

Step 18: Clarify the object.

Step 19: Define your last object, if you have one. I have crated this one.

Step 20: Clarify the object. This is a couch so I have cut into the crate.

Step 21: Trace the height of the window from the front to the back of the box.

Step 22: Trace the width of the window from the front to the back of the box.

Step 23: Clarify the window.

Step 24: Set the heights for the side windows by tracing and projecting from the back window.

Step 25: Set the depths of both side windows the same.

Step 26: Clarify the windows.

Step 27: Add depth to the windows.

Step 28: Clarify the windows.

Step 29: Clarify the drawing.
