Floor-Plan Symbols

Introduction

Floor plans for a proposed home:• Provide the owner an opportunity to

evaluate the design in terms of livability and suitability

• Quickly communicate overall construction requirements to the builder

• Reduce likelihood of errors if they are easy to read

Floor Plan Materials

Identified on the floor plan with:• Notes• Characteristic

symbols• Key symbols

Room Titles on Floor Plans

Rooms are labeled with a name on the floor plan

Other Floor Plan Symbols

patio, and driveways Attic Access can be placed in a closet

or hallway 22” x 30” 4” Floor Drains

Wall Symbols

With CAD, walls are draw to the exact thickness

No sheetrock included Studs are vertical construction members

• A 2 X 4 is actually ____” x _____”• A 2 X 6 is actually ____” x _____”• Frame 16” o.c.• 92 5/8” Studs

Opinions vary with regard to how walls are drawn• Exterior walls• Interior partitions

Wall Symbols

Room Components In AutoCAD Exterior walls – 3 1/2” or 5 1/2” Interior walls – 3 1/2” Interior plumbing wall – 5 1/2” Hallways - 37” minimum (38” if 26 door at end) Bedroom Closets - 25” deep by 49” wide min Base cabinets – 24 1/2” deep Upper cabinets – 12 1/2” deep

Wall and Partitions

Walls are shaded so they stand out from the rest of the drawing

Solar Tubes

Appliance Components

Water heater - 18” to 24” diameter

Refrigerator - 36” wide and 27” deep• Plan for 39” opening

Schedules• Numbered symbols on the floor plan key specific items to charts (i.e.,

schedules)– Set up many different ways– When doors and windows are described they must be keyed

Kitchen Cabinets

Bathroom Cabinets

&Simplified Method

of labeling

doors and windows

Plumbing Components

Double kitchen sink - 32” x 21” • (Need 36” wide cabinet)

Bathroom sink - 19” x 16” • (Need 24” cabinet)

Stairs

Stairs

Stairs• Width between 36” and 42”• Tread/ Run =width

- 10” Minimum• Riser = height

- 7.75” Maximum• Spiral stairs must have adequate headroom and

all risers must be equal height and smallest portion may not be smaller than 6”

Stairs on the Floor Plan DN = Down, UP = Up, R = Risers Rise is one riser and Run is one tread Always one less run than rise Stair length = tread length X number or runs Landings are at least 36” x 36” Stairwell opening can cover up to 1 ½ steps without

having to angle Calculating the stairwell opening required:6’-8” = 80”Max rise = 7.75”80/7.75= 10.3 or 11 risers11 x 10 runs = 110” or 9’-2”

Typical Stair Detail

Hallways on Floor Plans

Hallways provide access to various areas• May be long or short • Length and number should be minimal• May be a unique part of the design• Minimum finished width should be 36"

CAD Symbols made easy!

Floor-plan symbols can be placed using the AutoCAD Design Center or Tool Palettes

Use correct layers when inserting symbols
