Have you ever thought about the size of walls? When planning and designing your home, walls are an essential component. Walls support, they separate rooms, determine their size and characterize the respective building.
Walls can be categorized into exterior and interior walls . The exterior walls are defined as walls that separate the interior of the building from the exterior. The inner walls, in turn, are assigned the task of dividing the entire interior of a building into rooms of different sizes.
The planning and placement of walls therefore play a key role and should not be missing in any floor plan. In the following you will find some helpful tips so that you can plan and design the walls of your construction project independently and according to your wishes without much effort.

How do I plan and design exterior walls?

Before the interior is designed, the outer walls are defined and designed. Many interior rooms have at least one, and often several, exterior walls. These rooms therefore border on the outside area of ​​the building. When designing the exterior walls, there are a few things that should be considered. External walls must be drawn to scale so that the floor area of ​​the building can be measured precisely when designing the floor plan. They are also the eye-catcher of the building, serve as decoration and protection at the same time and should be preserved as long as possible. Outer walls are not uniform, they differ in their shape, arrangement and construction. There are few limits to the imagination and unique structures can be created.
With regard to the design, outer walls are drawn in as straight, thick lines. The thick lines are interrupted to make cutouts for planned windows or external doors.

How do I plan and design interior walls?

After planning the outer walls, the inner walls can be defined and designed. The different rooms are separated from each other with inner walls. Especially with regard to the interior design, the planning of the interior walls should be given an important role. In addition to the room layout, interior walls are essential with regard to thermal insulation and noise limitation.
In terms of design, interior walls are marked with straight, thin lines. As with the planning and design of the exterior walls, interior walls are drawn to scale. In this way, the room sizes can also be defined immediately and, if necessary, adjusted. Recesses are also made for doors or entrances, which are shown as an interruption in the drawn lines.

Do I have to specially mark load-bearing walls?

Load-bearing walls can be both interior and exterior walls. As the name suggests, they play an essential role in terms of statics, as the walls support the building. When planning load-bearing walls, it must be taken into account that they may not be demolished at a later point in time without appropriate measures. The marking of load-bearing walls is absolutely necessary in a construction drawing, but not in the floor plan.

What options are there for drawing walls?

There are two options for drawing a floor plan or building plan with interior and exterior walls. Each of these options has its advantages and disadvantages.
Would you just like to create a rough floor plan so that you can roughly imagine the building or roughly estimate rooms? Then you can draw the floor plan by hand. This is clearly the cheapest option. For this you need a block of graph paper, a sharp pencil, a set square and a very steady hand. Draw the lines straight and depending on the thickness (inner or outer wall). Disadvantages of this method are the high expenditure of time and the amount of work required if walls have to be adjusted or changed again afterwards.

However, are you looking for a detailed, professional-looking floor plan or building plan? In this case, you can create the floor plan or building plans with what is known as CAD software. This enables you to create a plan with just a few clicks of the mouse and change it without any effort. CAD software can make building planning much easier for you, and you can also discuss and adapt the plan with other partners, such as architects. The plans are becoming more realistic and more precise, especially in the 3D view. The biggest disadvantage here is the cost factor, CAD software is rarely free.
