Drawing For Interior Design

Convertions are an Interesting aspect of a plan drawings. As it is not possible to give the details of some elements which either to small, or otherwise too repetitive, such as doors, window, we use symbols.
DOORS AND WINDOWS
Doors: are shown open, their width to scale, indicating if they open inwards or outwards.
The symbol is simple, showing just the frame and the top the door (thickness may or may not me shown to scale.
Windows: (except fo the french windows) are shown by to perpendicular lines on the wall. They are usually shown shut.
CONVERTIONS REGARDING
LINESWhen you sketch, in a scale drawing the thickness of the lines must be consistent and regular, because they signify something. When you draw in ink, with instruments, the thickness is strictly controled.
A base line and contour
It shows and edge in the space, an outine, for example the top of a piece of furniture or the banister of the staircaase.
A thin line
This shows detail which are not structural – strips of parquet, motifs on the wall, elements in low relief.
Thin Dotted line
This shows the outline of large elements which are above the plan, such as a large beam, or the boundaries of the mezzanine or overhang.
The section line and the walls
When you draw a floor plan, in principle you show everything under a certain heigth. By convertions this is fixed at 1 meter from the ground, everything above is left out of the plan. On the floor plan these are shown cut off. To diference the section it is drawn with a Heavy Line.
The Stairs
You also shows what is under the stairs for example a small storage space. The banister is show by two lines and indicate the direction of the stairs draw a arrow, always indicating upstairs.
SHOWING FURNITURES AND EQUIPMENT
In general, pieces of furniture are not shown on the ground plan, since they are not permanent. But you can show them exactly or use some symbols.
Fixed sanitary ware is always shown (‘cause
there are not furniture). Kitchen is variable.
CHANGING AROUND THE FURNITURE
Get used to working on the floor plan laying out the different arrangements of furniture you could have in the same room.
ELEVATIONS AND SECTIONS
An elevation is a straigth- on view of a wall.
If you stand back, looking at the wall horizontally, you have a full- face view from the wall.
The principal is the same as the floor plan.
This can be called a Sectional Plan.
REARRANGING AN AREA OF WALL
Rethinking the layout of the flat doesn’t always mean moving interior walls. Rearrangings a wall panel, changing the decorations and objects displayed is itself an important modifications.
Design in modules
Take a measurement of the various elements to be included, and imagine the various different ways they could be put together.
MAKING A LAYOUTThe layout consist of producing a ground plan and elevations of a building, or one of its parts, after taking measurements on the spot.
There are thus two phases: Taking Measurements and Copying them on the documents.
Organisations of the layouts
We start with premilinary drawings on which we mark the measuments taken. Is the Stage between the sketch and the ground plan.
You can use some help, One to draw and take notes, and two to hold the tape when large areas are involved.
Sketch of the ground plan
Start by drawing a freehand plan and leave spaces around for for the measurements and notes.
The dimensions
They are indicated on a parallel line in the same direction, with small lines to indicate where the measuremnt runs and little bias to indicate that the measurement is not part of the drawing.
The amount of details required depends on your final intention.
The drawings in this stages show the progresive fine- tunings of the drawing as we sketch and verify the details.
