 The home owner  Architect  Designer  Contractor  Banker  Various Tradespeople Members of the team communicate through house plans.

 An important part of house plans contains information about the:  Size  Shape  Location of all parts of the house.

 Standard rules of drafting determine the types of:  Lines – (phantom, visible, hidden, center, dimension, extension, break and section)  Symbols – (plumbing, electrical fixtures, doors, windows, etc.)  Location of dimensions These are used in Architectural Drawings to insure that everyone in the team understands a house plan.

 Door and window symbols show the type of door or window and the direction each opens.  Mechanical symbols indicate plumbing, heating and air-conditioning fixtures  Electrical symbols include switches, wiring receptacles, light fixtures and appliances.

Freehand sketches of a proposed plan the designer uses in refining a design.

 Refined drawings or renderings to use for publication or for showing the design to a client.

 Drawings with detailed instructions to the builder to obtain necessary permits and erect the structure.

 Often a house plan or description refers to the total square feet in a home. Square footage is used to compare homes in terms of size. The higher the square footage, the larger the home will be.  Square footage is the total amount of living space (area) in the home.  You can determine the total living space by adding together the square footage space from all rooms. Determining Square Footage of a Home

 The dimensions of each room appear on the floor plan.  Note that closets, other storage space, and garages do not count toward the square footage of a house.

 Once you find the dimensions on the floor plan, use the following formula to determine the square footage of each room: Area = Length x Width  If a room is 12 feet long and 10 feet wide, the square footage will be the following: A = 12 ft. x 10 ft. A = 120 sq. ft.  To calculate the total square footage of a home, complete the calculation for each room and add them together.

An architectural drawing that is either smaller or larger than the actual object.  Drawings for a house are normally drawn at a scale of ¼” = 1’.  One-foot measures on the house equals one-fourth inch in the drawing.  Scale can also be written as: ¼” = 1’0”½” = 1’0” 1/8” = 1’0” 1/16” = 1’0” and so on...

How to Draw an Interior Design Floor Plan

 As you look at floor plans, you will notice that certain rooms of a house are usually located next to one another.  This is because certain rooms serve similar purposes, or functions.  Grouping rooms together by functional zone is an efficient way to organize space.  3 zones encompass most of the space within a house: private, work and social area

Grouping Zones by Function Quiet Area: Bedrooms Bathrooms Den / Library Work Area: o Kitchen o Laundry Area o Utility Room o Garage o Workshop / Sewing Room o Home Office Social Area:  Entrances  Dining Rooms  Living Rooms  Family Rooms

 Also known as social zones, they are used for activities and entertainment.  In residential interiors, this zone includes living rooms, game rooms, family rooms, entryways or foyers, as well as patios and decks.  In nonresidential interiors, this zone includes waiting rooms, reception areas, break rooms, conference rooms, and atriums.

 Transitional zones (or circulation zones) are semipublic or semiprivate spaces used for circulation and flow of traffic between the major zones. - Transitional zones include entryways, exits, hallways, and designated passageways within the space.
