2. it is made of carefull selected quality components and appropriate materials.
3. it is aesthetically pleasing.
Space Planning - Answers Effectively utilizing the overall area that a project encompasses.
Space Planner/Residential Interior Designer - Answers This person's role is to be the liaison
between the architecture and function of the designed space.
Relative Size - Answers how big something is in comparison to something else.
Absolute Size - Answers refers to the literal dimension of a space or object.
Scale - Answers relates to size in that someone may say "This is a large scale room."
Rooms are often 'drawn to scale; on graph paper or blue prints using a scale of - Answers
1/4"=1 foot
Space - Answers The area in which shapes and forms exist, is most frequently a room defined
by the planes of walls, floor and ceiling.
Positive Space - Answers Solids or forms
Negative Space - Answers The area that surrounds the solids or forms
Proportion - Answers Eye-pleasing relationship between various parts and the whole. (Ex. Queen
Anne or Chippendale chairs are well-proportion because the seat, legs and back relate well to
eachother).
The Greeks - Answers Discovered that ratios that best serve our human needs lie between 1:1
and 2:1.
Pi: the most eye pleasing and useful ratio - Answers 1:1.618
Leonardo da Vinci - Answers Developed a system of proportions using the human figure with
outstretched arms and spread legs, with arms and legs touching a circle inscribed in a square.
Anthropometry - Answers the scientific study of the measurements and proportions of the
human body.
Ergonomics - Answers The study of workplace equipment design or how to arrange and design
devices, machines, or work space so that people and things interact safely and most efficiently.
,Textures - Answers The actual and perceived details on a surface and describe the relative
roughness or smoothness of a surface, the hardness and softness as well.
The Golden Ratio - Answers Seemingly magical relationship with the
Fibonacci Series turn out to relate directly to
natural phenomena such as the clockwise and
anticlockwise spirals on the surface of
pinecones and pineapples and in the centers
of daisies.
Radial balance - Answers Is based on a circle with elements arranged
around a single point.
Symmetrical - Answers The "Mirror" effect, or when one object is reflected across a plane to
create another instance of itself.
Symmetrical Balance - Answers Often associated with formal rooms or traditional interiors.
Consider this when choosing objects for a mantle.
Asymetrical balance - Answers distribution achieved by arranging non-identical elements on
both sides of an imaginary center line on the screen. (Associated with contemporary, casual, or
country interiors)
Rhythm - Answers involves the repetition of elements in space. Can provide a theme for a room
that the eye enjoys following. (Ex: Stadium Seats can create rhythm and balance)
Emphasis - Answers the focal point of a space or object. (Ex. fireplace or large window)
Structural Patterns - Answers Those usually created by architectural members or decorative
construction techniques and are three-dimensional.
Applied Pattern - Answers Typically a decorative design used on a flat surface and is almost
always based on the repetition of smaller design motifs.
Ornamentation - Answers Visual extras added to enrich a design.
Normal Traffic Pattern - Answers 24"-30", but 36" or more is best.
Comfortable range of distance for conversation - Answers 4 and 10 feet
Patterns - Answers Create perceived textures.
The most used materials for both structural
, soundness and interior enhancement are: - Answers 1) wood, both soft and hard, 2) masonry,
that is
stone and manufactured materials such as brick,
concrete block, tile, mud brick and gypsum block,
3) metals such as iron, steel, aluminum, brass,
bronze, chromium and copper 4) glass, which
can be transparent, mirrored or opaque and 5)
plastics, which are made by chemically combining
various resins or other ingredients with
petroleum, and 6) other new materials,
sometimes called hybrids, which result from new
processes of production that often combine
natural and man-made materials. An example
would be recycled rubber and cork mixed with
plastic to form floor tile.
Concrete - Answers a wet combination of cement, aggregate and water mixed together.
Cement - Answers A dry mix of chalk and clay ground into fine particles then heated until they
fuse together to form ball-shaped particles of cement clinker.
Aggregate - Answers materials are gravels and sands used to form the bulk in the concrete mix.
Aggregates are
classed as fine (sand) or coarse(gravel). Coarse and fine are often mixed together and are
called
all-in aggregate. Clinker, clay or pumice may also be used as aggregates.
Strength of Concrete - Answers primarily determined by the ratio of water to cement. The less
water
used, the stronger the concrete.
Steel - Answers Made by removing some of the carbon content of iron. Prone to failure in fire
when temperatures go above 550 degrees Celsius. Steel is coated with sprayed concrete or
