Explore the technicalities of wall sections and details in architectural drawings, from their representation in relation to building sections to the specifics of sound insulation and fire safety. Learn how these intricate details are conveyed and interlinked across different sections and pages of architectural designs.
Key Insights
- A wall section, larger than a building section, details the components around a wall system, including specific features such as air gaps and layers of gyp board for sound insulation and fire safety.
- Details within the wall sections are marked out for reference, such as roof slope, insulation, and specific areas of interest. These are hyperlinked to their respective detailed drawings on different pages, creating an interconnected web of information within the architectural design.
- The scale of representation varies across different sections - building sections might be depicted at a quarter inch equals a foot, wall sections at half an inch equals a foot, and details at larger scales. This facilitates the focus on intricate details within the design.

The next pages I'd like to review will be our wall sections and our details. I think we all understand that a plan is a horizontal slice through a building. A building section is a slice through the entire building.
A wall section is a limited component of a building section, which is normally confined to the area around a wall system itself. If, for example, the building section is drawn at a quarter inch equals a foot, a wall section is twice as large. So it's going to be drawn at half inches equals a foot.
So since it's twice as large, it can show a whole lot more detail. You can see that we have three typical sections here. This party wall section is not relevant for our particular plan, but for another of the houses built in the neighborhood, they have some party walls because they're duplex units.
And then we have standard wall sections for the houses themselves. If I, for example, look at the wall section for the party wall, you're going to notice a couple of things. You'll see a whole bunch of detail as far as how information has to be framed.
You'll notice that I have some vertical studs here and here. You can see that I have an air gap between the two suds. Believe it or not, that air gap with the combination of the multiple layers of gyp board and the air gap, I get really good sound insulation so that the neighbors cannot hear one another.

You'll also notice that the two layers of gyp board go from the floor all the way to the roof. We have two layers of gyp board here, two layers of gyp board here. This is a fire rated wall.
So this way of fire in one side, if it were to happen, could not go on to the other side of the house. The combination of the gyp board, the wood studs, the insulation and the air gap gives us a sound transfer coefficient, which is what's required to make sure that neighbors cannot hear one another. Now, one thing you'll probably notice too, is that when we have been working on the floor plans, we've had keynotes everywhere.
It is very typical to have keynotes on the larger plans. But when you start getting into wall sections and most typically details, rather than having keynotes, you will see the information spelled out. On this wall section over here on the left, what you'll notice is that I'm showing the roof coming down here.
I'm showing the 5 and 12 roof slope right here. I have my call outs of what these are pointing to. So fiberglass shingles, this call out here, you follow this line and then down to this arrow here.
So it's calling out that that's a fiberglass shingle. I have the insulation. What I'd like to bring to your attention though, is this area right through here.
You can see that it is bubbled out. You can see that this will be a detail, which will be detail number one on page A9.2. And it's coming from page 9.0. Again, I have a bubbled out area here. And the detail number for that will be detail four on sheet A9.1. And it's coming from A9.0. You can see that I have some structural information here, but you can also see that the information that's being called out is saying dimensions per structural.
So again, we're dealing with a structural reference in this area. We are not calling out the specific dimensions here, but rather we are saying to go on and look at the structural pages to find that information. Now, on this wall section, I have a couple of fun things happening.
I'm showing my roof slope. That's five and twelve. This ceiling here is the vaulted ceiling in the living room.
So I'm telling it what the slope of the roof is inside. So it's a five and twelve outside. It's a two and a half twelve on the inside.
You can see I have a bubbled out area here. And that bubbled area is detail number two on page A9.1. And it's coming from page A9. You'll notice a break line happening here.
So I have a break going on in this area and a break going on in this area. And I'm simply saying, hey, in order for this detail to fit within this area, I need to go on and not show this component of the wall. And because I'm breaking it, I'm also saying the information that's in this area that I'm showing you right now is not all that critical.
Because what I really want to show is references to that detail, references to that detail, and references to that detail. So again, we have building sections. We have wall sections.
And we have details. And you can tell the building section might be a quarter inch equals a foot. The wall section at half an inch equals a foot.
And the details might be at an inch equals a foot, three inches equals a foot, inch and a half equals a foot. But again, as I zoom in on details, I'm going to be zooming in more and more on the different information that's conveyed there. So this is the wall section page.
