Design and construction of a house involves:

The home owner Architect Designer Contractor Banker Various Tradespeople

Members of the team communicate through house plans.

Architectural Drawings

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

Architectural Drawings

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.

Architectural Symbols

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.

Schematic Drawings

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

Presentation Drawings

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

Construction Drawings

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

Math Matters

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

Math Matters

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.

Determining Square Footage of a Home

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.

Drawing to Scale

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

Floor Plan






Grouping by Functional Zones

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 Kitcheno Laundry Areao Utility Roomo Garageo Workshop / Sewing

Roomo Home Office

Social Area: Entrances Dining Rooms Living Rooms Family Rooms

Space Planning: Zone Types

Public Zones (or Social Area)

Private Zones (or Quiet Area)

Service Zones (Work Area)

Transitional Zones (or Circulation Zones)Commercial / Nonresidential Floor Plans

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.

Public Zone


In non-residential interiors, this zone includes offices, restrooms, libraries, and similar room settings.

In residential interiors, this zone includes bedrooms, bathrooms, and home offices.

Private / Quiet Zone


Service zones (or other work zones) are those areas where work is done.- In residential interiors, this zone

includes the kitchen, utility room, workshop, and the garage.

- In nonresidential interiors, this zone includes workrooms, mailrooms, kitchens, maintenance areas, packing areas, and shipping rooms.



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.



Today’s Activity
