The document discusses several key concepts in interior design including: - Color theory and the meanings associated with different colors like black, white, red, green, blue, and purple. - Design principles such as balance, scale, rhythm, emphasis, contrast, and unity. Symmetrical and asymmetrical balance and radial balance are explained. - Scale and proportion in interior design and how furniture should be scaled to the room. - Rhythm as the repetition of design elements in space. Emphasis is used to create focal points. Contrast and unity/harmony are also covered. - Common floor, wall, and ceiling finishes that can be used. - The typical stages of an interior design

1. Interior Design

14. Black - authority
White – innocence and purity
Red – passion, anger, and
appetite
Green – wealth, nature, relaxing
Blue – peace, royal
Purple – luxury, wealth,
sophistication

Emphasis
Contrast
Unity

17. Balance

18. SYMMETRICAL BALANCE
 Formal Balance
 Mirror Image
 Easy to appreciate and
create

19. Asymmetrical Balance
 Informal Balance
 Visual weights are equal
 Elements differ on each
side of the axis

20. RADIAL BALANCE
 All parts are
balanced and
repeated around a
center point.

21. SCALE AND PROPORTION
 Both are closely related.
 Relate to size and shape of things.
 Proportion refers to the relationship of one part
to another or to the whole.
 Scale deals with the absolute size, character and
visual weight of an object or space compared to
other objects in the same space.

22. Furniture should be scaled to fit the room. Always
consider human scale when planning an interior.
This bed has an odd proportion when compared to
the room.

23. RHYTHM
 The design principle of rhythm is based on the repetition of elements in
space and time.

24. Focus/Emphasis
• Emphasis in interior
design is used to create
focal point in design.

25. • Putting two elements in opposition to one
another.
Contrast

26. Unity& Harmony
• Unity is achieved
when all the
different elements
is a design work
together to create a
unified whole.

27. Finishing

28. FLOOR FINISHES

29. WALL FINISHES

30. CEILING FINISHES
painted ceiling
panels
wood strips
wood
glass ceiling
fabric stripes
bricks

 Concept
 Developed
 Technical
 Procurement
 Project Co-ordination
