How to Read a Floor Plan: Symbols, Dimensions, and What “Optional” Means on a Builder’s Plan

Couple planning home layouts while reviewing blueprints and discussing ideas.

A floor plan packs a lot onto one page: room sizes, closet locations, stair directions, and labels like “OPTIONAL GARAGE” that quietly affect your price. Learning how to read a floor plan is the best way to know exactly what you’re getting before you build. This guide walks through real Value Built Homes plans, label by label.

Key Takeaways

  • Room sizes are written in feet and inches. On the Value Built Homes Cardinal plan, “16’0 x 13’0” means a room 16 feet 0 inches by 13 feet 0 inches.
  • Use the printed dimensions, not a ruler. The Value Built Homes Cardinal and Dove web plans don’t print a drawing scale.
  • Abbreviations mark features and locations. W.I.C. means walk-in closet, WH means water heater, and DW means dishwasher, while “D” can mean door or dryer, so read it in context.
  • The level totals add up to the listed square footage. On the Value Built Homes Dove plan, the 1,200 SF main level and 584 SF upper level add up to the listed 1,784 sq. ft.
  • “Optional” means add-on. At Value Built Homes, if it’s part of the standard plan, it’s included; an optional garage or optional porch is an add-on.
  • Basements are never standard. At Value Built Homes, a basement is always an optional add-on, and plans show only where its stairs would go.

What the Labels on a Value Built Homes Floor Plan Mean

The labels on a Value Built Homes floor plan tell you a room’s size, where a feature is, or whether something is standard or an add-on. Value Built Homes floor plans range from 870 to 2,514 square feet, and this guide uses two as examples because together they show every label in the table below:

  • The Dove floor plan: This 1,784 sq. ft., 3-bedroom, two-story Value Built Homes plan has alternate Plan ‘B’ and Plan ‘C’ layouts.
  • The Cardinal floor plan: This 2,514 sq. ft., 5-bedroom, two-story Value Built Homes plan includes an option note showing how one choice changes another part of the plan.

Smaller one-story Value Built Homes plans like the Robin and the Sparrow use the same OPTIONAL GARAGE, OPTIONAL PORCH, and BASEMENT ACCESS PLAN labels. The table decodes each label as printed, with what it tells you as a buyer.

What Is a Floor Plan, and How Is It Different From an Elevation?

A floor plan is a drawing of one level of a house seen from directly above, as if the roof were lifted off. An elevation is a straight-on view of the outside, showing what the front, side, or rear of the home will look like.

The Value Built Homes Cardinal and Dove plan PDFs each include both, plus an options sheet:

  • Level plans: Each floor gets its own drawing, titled with its square footage.
  • Elevations: These exterior views are labeled by side, such as “FRONT ELEVATION” and “SIDE ELEVATION W/ GARAGE.”
  • Options sheet: This sheet shows the add-ons available for that plan.

How Are Walls, Doors, Windows, and Stairs Drawn on a Floor Plan?

Floor plans draw walls as solid lines, doors as gaps with a swing arc, windows as breaks in the wall, and stairs with an arrow pointing up:

On a builder’s plan, the labels matter more, because that’s where the price information lives.

How Do You Read the Dimensions on a Floor Plan?

Room dimensions are two measurements in feet and inches, separated by an “x.” On the Value Built Homes Cardinal plan, “BEDROOM 1 / 16’0 x 13’0” means the bedroom is 16 feet 0 inches by 13 feet 0 inches. Here’s how to decode the notation:

  • The number before the foot mark (‘) is feet, and the number after it is inches. On the Value Built Homes Dove plan, 13’6 means 13 feet 6 inches, and “9’0 x 9’8” is 9 feet 0 inches by 9 feet 8 inches.
  • Formats can vary within the same set of plans. The Value Built Homes Cardinal garage is printed 21′-0″x21′-0″ while the Dove garage reads 21’0 x 21’0. Both mean 21 feet by 21 feet.

To picture what those numbers feel like, see our guide to room sizing for your home layout.

Can You Measure a Floor Plan With a Ruler?

Not on the Value Built Homes Cardinal or Dove web plans. Neither plan PDF prints a drawing scale, and zooming or printing changes the drawing’s size. Rely on the dimensions printed in each room.

How Is the Square Footage on a Floor Plan Calculated?

On Value Built Homes plans, total square footage is the sum of the square footage printed for each level. On the Value Built Homes Dove, the 1,200 SF main level and 584 SF upper level make 1,784 sq. ft., and on the Cardinal, two 1,257 SF levels make 2,514 sq. ft.

Why Don’t Room Sizes Add Up to the Total Square Footage?

Room sizes describe individual rooms, while square footage covers the whole level. Four rules explain the gap:

Does a Basement Count in a Home’s Square Footage?

A basement is reported separately: the ANSI standard involves calculating and reporting above-grade and below-grade square footage as two figures. As Morley put it in 2022: “Living space that is below grade, even if it’s only a foot or two, is to be considered basement space.”

At Value Built Homes, a basement is always an optional add-on, which is why plans show a “BASEMENT ACCESS OPTION” or “BASEMENT ACCESS PLAN” for the stairs.

What Does “Optional” Mean on a Builder’s Floor Plan?

On a Value Built Homes floor plan, “optional” means add-on. If it’s part of the standard plan, it’s included. If it’s not, it’s an optional add-on.

Put simply, the physical things you can see in the standard plan are what you get, and if it isn’t shown, it isn’t there. Our list of what’s included in a new construction home applies this rule to the whole build.

Optional Garages, Porches, and Basements on a Value Built Homes Plan

Three add-ons appear on the Value Built Homes Cardinal and Dove options sheets:

  • Garage: The garage is labeled “OPTIONAL GARAGE” on the Dove and “GARAGE OPTION” on the Cardinal. A garage is included when it’s part of the standard plan; otherwise it’s optional.
  • Porch: Porches come in 6’0 X 6’0, 6’0 X 12’0, and 6’0 X 24’0 sizes with shed or gabled roofs. A porch is included only when it’s part of the standard plan and the roofline is built for one.
  • Basement: The basement access option shows where stairs would go. A basement is always an optional add-on.

How Choosing One Option Can Change Other Parts of the Plan

Options can affect more than one spot on the plan:

  • Option notes: The Value Built Homes Cardinal plan notes “BEDROOM 4 WINDOW MOVED TO SIDE WALL,” meaning one choice changes another detail.
  • Elevations drawn with an option: “FRONT ELEVATION W/ GARAGE” shows the home with that add-on. It’s a preview of the option, not the base plan.

Because the layout is set by the plan, your plan choices live on the options sheet, and finishes come from a curated set. That keeps decisions simple.

How to Read a Floor Plan When You’re Buying New Construction

When buying new construction, read the plan for how the home will live and what’s in the price, in this order:

  1. Check the level totals. Confirm the per-level square footage adds up to the total on the plan page.
  2. Read each room’s dimensions. Picture your furniture using the printed numbers, not a ruler.
  3. Find the abbreviations. Locate the W.I.C., WH, kitchen appliances, and laundry, reading any “D” in context.
  4. Circle every “optional” label. Garages, porches, basement access, and Plan ‘B’ or ‘C’ are add-ons.
  5. Read the option notes and elevations. Look for changes like a moved window and elevations drawn “W/” an option.
  6. Bring your questions to the team. Ask about anything unfinished or optional.

Frequently Asked Questions About Reading a Floor Plan

What does W.I.C. mean on a floor plan?

W.I.C. means walk-in closet. You’ll see it on Value Built Homes plans like the Cardinal and the Dove, and it’s part of the plan as drawn.

If something is drawn on a builder’s floor plan, is it included?

Not always. At Value Built Homes, anything that’s part of the standard plan is included, and anything labeled optional is an add-on. A garage or porch on an options sheet, or an elevation drawn “W/ GARAGE,” shows an add-on.

Why doesn’t the square footage match the room sizes added together?

Because they measure different things. Square footage under the national standard is measured from the exterior walls (per a 2022 REALTOR Magazine article), so walls, hallways, closets, and stairwells count toward it, while open areas don’t. Room sizes describe individual rooms.

Are the appliances shown on a floor plan included?

At Value Built Homes, the kitchen appliances are included: a refrigerator, stove, microwave, and dishwasher come with every floor plan. The “D / W” in the utility room marks where the dryer and washer go, but it’s a location only, and washers and dryers aren’t part of the standard package.

Can I change the layout of a Value Built Homes floor plan?

The layout is set by the plan you choose, which helps keep pricing and timelines predictable. Your choices come from the plan’s options sheet and from a curated set of finishes.
