Detail Floor Plan Explained (4 of 11)

The Detail Floor Plan sheet holds a lot of information. The home’s exterior footprint, openings and interior rooms are carefully dimensioned. Each room is clearly labeled along with things like attic access, ceiling details, and water heaters. This can sometimes look like a jumble of lines going this way and that. If you take a moment it is not hard to tell what is going on.




In the Detail Floor plan the walls are easy to see, and the doorways are also easy to see. The doors will have a sweeping arch line that shows which way the doors open. Windows are shown as breaks in the walls. And sliding glass doors are shown as staggered windows, you can see how they will slide across each other.

Dimensions are typically shown in feet and inches, however we can always convert the plan to metric. You will also see numbers in circles and letters in polygons. These refer to the window and door schedule.

Typically on the Detail Floor Plan there will be a Window and Door schedules. A schedule is just another name for a list. Each list has specific information on the style, size and even manufacturer of product. On our larger house plans we will often create a separate floor plan dimension plan and call out plan for simplicity.

Door Schedule

The Door Schedule will have at least 3 columns, the Mark, Size, and Description. The Mark will show what shape will be used in the floor plan. The Size is just that, but at first it doesn’t look like a number. For example a door may have a size of 2868 – the number alternates between feet and inches, first number is feet, second is inches, third is feet again and the last is inches. That makes that number 2′ 8″ x 6′ 8″. The first set of numbers, 2′ 8″ is the width, the second set, 6′ 8″ is the height. Sometimes there is an additional number like this (2)2080, this means it is a double door. It means Two Doors at 2′ 0″ wide by 8′ 0″ tall. The Description is fairly self explanatory.

The Mark is used in the floor plan. By each doorway you will see the Mark with a number in it. By matching the number in the Mark to the Door Schedule you will find the door information for that location. You will notice that door openings usually do not show dimensions, thats because the door dimensions are kept in the Door Schedule.

Window Schedule

The Window Schedule is about the same as the Door Schedule. There is Mark, Size, Remarks, Description, and sometimes Quantity. The primary difference is with the Size. We have a long and valued relationship with Andersen Windows. We have found them to be of the best quality and the most efficient. Because of that we list the Size in Andersen Window product numbers. You can go online and get all the information for each product number from Andersen Window.

Just as with the doors, each window opening on the floor plan will have a Mark with a letter in it. That letter will refer to the Window Schedule. The main reason we use window product numbers is because windows will have a lot of details. The casing, moldings, shape, type of glass, and the latching.

You are not required to use Andersen Windows, encouraged, but not required. You can have your builder or your windows person translate the Andersen Window numbers into other brands sizes and products.

The Area Tab

Typically Detail Floor Plans will also includes the square footage information. The is called the Area Tab. The Area Tab will show the most important square foot totals. It doesn’t show all the square footage. The most important thing is the Total Living, this number is what is used to estimate the cost of building the home.

In our next installment we will reflect on the Reflected Ceiling Plan.
