Floor plans, are scaled drawings of rooms, homes or buildings as viewed from above. Floor plans provide visual tools for the arrangement of rooms, doors, furniture and such built-in features as fireplaces. They can serve as guides to planning, budgeting and choosing building materials for homeowners and remodelers.

Blueprints are more technical and detailed diagrams for construction or remodeling projects. Blueprints, also called building plans, provide specific information, including electrical and plumbing systems, that remodelers or contractors use to complete a job. 

Blueprints usually include the following features, which may not be in floor plans:

• Exterior elevation views of homes or buildings

• Grading & foundation plans

• Electrical & plumbing plans

• Cutaway views of framing

• Details of features such as foundation footings & staircases

Most local governments require complete blueprints as part of the permit application process.

Follow these steps when you draw tiny house building plans. 

• When drawing a floor plan by hand, use grid or graph paper and a ruler to ensure the measurements are exact.

• Traditionally, floor plans are drawn to 1/4-inch scale, with 1/4 inch representing one foot.

• Draw the plan using a pencil, making light marks for easy changes.

• Draw and label the room layout and architectural features. Standard door dimensions are 2 feet 8 inches.

• Note the building's north/south orientation and the directions the windows face. This allows you to consider when and where sunlight falls on the house.

• Indicate the locations of permanent outlets, switches, vent covers, etc. for furniture arrangement.

• Draw desired furniture pieces to scale. Consider cutting out paper furniture to arrange on top of the plans and determine placement.

• At the bottom right corner, provide a title block with the floor plan creator’s name, the homeowner’s name and the architectural scale

Make your process more efficient with these tips for drawing floor plans.

Use common floor plan symbols as seen in the graphic above.

• Allow 5-6 inches between exterior and interior walls.

• Make sure the plan is flexible enough to provide adequate storage.

• Arrange furniture to allow for traffic. Provide at least 18 inches between furnishings where passage is needed, such as between a sofa and a coffee table. Allow less space in areas where no passage is needed, such as between a sofa and an end table.

• Allow 30-48 inches of space for areas where two people may occupy the same pathway. Allow 24-36 inches for areas where one person will travel at a time.

• Allow at least 36 inches for spaces where wheelchairs must have access, and 48 inches where wheelchairs must make a U-turn. Bathrooms must have a minimum wheelchair space of 30 inches wide by 48 inches deep to meet ADA requirements.

• Finish the floor plan by erasing stray marks and mistakes.
