It’s important to figure out the walls in your plans as they determine the spatial layout of your apartment.
Structural walls: These walls are probably the first thing that you’ll notice in a floor plan. They appear as thick, solid lines and cannot be hacked away or modified with given structural concerns.
Non-structural walls: Walls that can be hacked away on the other hand, appear as a pair of lines with an empty space in between.

2. Doors

There are many symbols representing the different types of doors. Keep in mind that the location of your doors can be changed or customised as long as they are constructed along hackable (non-structural) walls.
Non-included doors: Door symbols which are drawn with dotted or dashed lines refer to doors that are not provided by HDB. Do note that HDB only provides you with doors that uses solid strokes in your floor plans.
Swing doors: Swing doors appear as a quarter circle in floor plans, with the rounded and straight line indicating the size of the swing radius and the actual door respectively. Avoid placing or building anything within the swing radius.
Folding doors: Folding doors are represented by a V or zigzag shape in floor plans and they are commonly found in bathrooms and service yards, with each line referring to one sliding panel.

3. Windows

Similar to doors, windows also have numerous symbols that represent their different types. They are however, trickier to figure out given their smaller sizes on floor plans.
Casement windows: These windows operate similar to doors in the sense that they open on hinges and pivots. Likewise, their symbols resemble that of swing doors, with the exception of a straight line across the swing radius.
Top hung windows: Small top-hung windows are those small openings that you usually see at the top of bathrooms. Their purpose is to provide ventilation to bathrooms. You’ll find them drawn as a dashed line that is sandwiched by two other solid lines.
Sliding windows: Sliding windows are represented as thin, jagged lines in between the walls, which can be difficult to find at first. As they do not have a swing radius, you can place objects directly in front of it.
