How to Draw a Blueprint for a House

Creating a home blueprint can be an easier way to plan out a house to exact specifications.

According to Make Your Own House, it "can cost nearly $2,000" to have it professionally done, so drafting plans yourself saves money and gives the added benefit of complete control. Drawing correct blueprints can be a little discouraging. With a little help and the right tools, you'll be on your way to creating the blueprints for that dream home.

Determine what areas of the house will have the most traffic. For example: the mud room, living room and kitchen may be the rooms with the most people in them at any given time. These areas need to be large enough to accommodate people, so plan on making those rooms bigger.

Determine the general size of the rooms. The living room might be 14 feet by 18 feet, the dining room might be 14 feet by 14 feet and so on. Write out all the rooms and measurements on a sheet of paper.

Use some paper and begin sketching the rough draft of the home. Organize the rooms in a way that are most efficient. For example, put the front door into an entrance way that is open and unblocked, with few or no walls around it. Add the living room near the entrance. The bedrooms need to be farther away, usually grouped in the same general location. The kitchen and dining room need to be relatively close and if plans include having an "eating area" or a "breakfast nook," it needs to be in the kitchen. When done with the rough draft, move on to complete the first real draft.

Use the scale ruler to begin with the outside walls and construct the perimeter of the house. Make them an one-eighth of an inch thick by drawing a second line 1/8-inch away from the first line drawn.

Draw the inside walls of the house. Keep in mind that if designing a home with a second story, the walls in the first story need to be close enough to support a second story. (For example, do not add a 50 foot by 50 foot room with multiple rooms above it, because the ceiling will collapse unless beams are added on the first floor). Consult an engineer with building load questions, if necessary.

Add closets to bedrooms and include bathrooms off the bedrooms that need it. Decide how many bathrooms the entire house will have. Include symbols for wiring and plumbing in the appropriate rooms.

Finish by visualizing a walk through the house. Ensure hallways are at least wide enough to get through (and wider to increase the resell value--four feet is considered small). Also make sure doors all open easily without hitting other doors or walls (see Resource 1).

Things You Will Need

  • Scale Ruler
  • Pencil
  • 18 x 24 inch paper
  • T-square


  • Understand the basics: the house needs to be drawn to the correct scale. Usually, houses are drawn on a 1/4-inch to one foot scale, meaning that every 1/4 of an inch on paper will be a foot in reality. Draw this accurately using the scale ruler.


  • Consider making doorways and hallways, as well as toilet fixtures wheelchair accessible. Homes that are multifunctional have better resell value.
