We explain each of these in more than detail below.

Remember That House Plan Blueprints Are Drawn to Scale

When looking at the impress drawings, recall that they are drawn to a calibration then that if any specific needed dimension is missing, the contractor tin scale the cartoon to determine the correct measurement. The main flooring plans are generally drawn to ane/4" scale, which means that every 1/4" on the program equals 1' in bodily length. Other details, such as framing layouts or built-in details, may be fatigued at some other scale as ane/8".

Dimensions may be drawn betwixt the walls to specify room sizes and wall lengths. These plans will aid you visualize the unabridged interior layout of the domicile from where the master chamber will be located to the open layout of the kitchen and living room.

Solid lines in a floor program point structures in walls (shelving, fireplace, etc.) and on floors (cabinets, kitchen islands, appliances, sometimes furniture, etc.), and dashed lines in a floor plan usually bespeak something three-dimensional that tin can't be seen in outline on the flooring, such every bit a vaulted ceiling, tray ceiling, beamed ceiling, or overhead doors in a garage-door opening.

A swing door is typically shown as a straight line perpendicular to the wall, with a curved arc line that connects the line to the wall. The curved line shows how the door swings open, correct to left or vice versa, and into which room it opens. Other doors are shown differently:

  • Folding doors: drawn as a little "V" shape (shown in partially folded position)
  • Cased openings in walls (no door) will unremarkably be indicated by dashed lines

Windows (double-hung) are usually shown with iii parallel lines in a wall, which is easy to remember: think ii walls and pane of glass. Casement windows may be shown with three lines just with the addition of a swing arc line like that used to evidence doors or with a pair of windows shown partially open.

You'll also see on the floor plan locations of plumbing equipment like sinks, water heaters, furnaces, etc. Amidst the walls and dimensions, you will oftentimes find notes to specify finishes, construction methods, or fifty-fifty symbols for electrical or to reference cantankerous-sections.

Exterior Elevations

Elevations are a non-perspective view of the home. These are drawn to scale then that measurements can be taken for whatsoever aspect necessary. Plans include front, rear, and both side elevations.
