How To Interpret A Blueprint For A House?

The floor plans (also known as house plans, house blueprints or house blue prints) — and all of the other drawings in a plan set set — are drawn to scale, often one-quarter or one-eighth of an inch, meaning every one-quarter or one-eighth of an inch on the blueprints equals one foot in actual size. The simplest method for translating scale measurements into their actual size is to measure them with a scale ruler, which will indicate the conversion directly on the ruler. (Scale rulers are available at any crafts store and at many drugstores). Alternately, you can figure the conversion in your head. On plans drawn to a one-quarter of an inch scale, for instance, two inches equal eight feet of true space. Each page of the drawings should be labeled to indicate what size scale the architect or home designer used when drafting the plans.

Some measurements, such as room dimensions, will be labeled directly on the blueprints with their actual size. These measurements are indicated with dimension lines, which consist of a solid line with a mark at either end. The space between the two marks equals the distance noted next to the line. (Some vertical measurements may also be indicated with dimension lines. A cross-section, for instance, will usually include a dimension line that notes the height of the ceiling in a room.)

Usually door swings are noted as a short straight line linked to a short curving line (the swing or arc of the door). There might also be pocket doors, which are indicated with a thick wall line intersecting a short thin line across an opening. Kitchen and bathroom sinks, toilets, and some furniture will be shown. Stairways will have arrows and the words "up" or "down" to indicate which part of the stair goes in which direction. For example, the plan shown below, includes door swings, sliding or pocket doors in the pantry, all sinks and toilets, and the stairway with up and down arrows.

You will probably also notice a number of circles, triangles, or hexagons with numbers inside of them. Placed next to windows and doors — and sometimes next to other elements, such as lighting or plumbing fixtures — these notations correspond to those on the window, door, plumbing, and electrical schedules found at the back of the plan set. These schedules indicate the size and types of the doors and windows to be used, and sometimes even the manufacturer and model numbers, as well.

When reading the floor plans, you will probably notice a few circles with numbers and letters inside of them. These symbols are used to indicate a cross-section of that particular room or space that can be found elsewhere in the blueprints. Often, a single page of the blueprints will include two or three cross-section drawings. The number in the circle indicates which page the cross-section is located on, while the letter notes which cross-section on that page is being indicated. Sometimes, the circle will also include an arrow on one side that points in the direction of the view depicted in the cross-section.

And finally, while the symbols used in house blueprints are too numerous to mention, you should be familiar with the most standard. Thick, solid lines are used to indicate full-height walls, while thin, solid lines indicate other built-in structures, such as cabinets, bookshelves, or plumbing fixtures. Thin, dotted lines indicate overhead features, such as wall cabinets in a kitchen or a special ceiling treatment or an archway in the living room.
