Creating Interior Walls for Kitchen, Laundry, Closet and Furnace Area Using Precision Offsets and Trims

Learn to build accurate interior walls for key home areas using offset, trim, and fillet tools—step by step guidance for kitchen, laundry, closet, and furnace layout.

This article provides a detailed guide on how to structure the interior walls of a house, specifically focusing on the kitchen, laundry room, and front entryway closet. It details the process of calculating and executing precise offsets for each wall, ensuring symmetry and accurate distances.

Key Insights

  • The article offers an in-depth guide on how to calculate and execute precise offsets while constructing interior walls. This includes maintaining uniform distances from exterior walls to interior walls, and between interior walls themselves.
  • It uses specific examples from a house design, including the kitchen, laundry room, and front entryway closet to illustrate the process. The tutorial involves precise measurements, trimming, offsets, and fillets to ensure a symmetrical layout.
  • The article also discusses how to handle door openings in the design, providing two potential methods - breaking the line into two and then using fillets on each side, or simply extending and trimming.

Let's zoom in and work on the kitchen, laundry room, and the front entryway closet. If we zoom in, let's first look at the kitchen.

We can see that the kitchen is a fairly simple u-shape here, and the offset distance is going to be nine foot two and a half from the exterior wall to the right side of this interior wall. So that means that we can offset this line and this line a distance of nine foot two and a half to generate both lines for our kitchen wall. Let's do that now.

O, enter for offset, nine feet two point five, enter. I'll grab this line to the left and this line to the left. Let's hit ENTER to say that we're done.

And there is one more offset here for this small furnace, but for now we can see that the line of garage, which is this edge here, in fact it's these two lines, continues up to meet with this horizontal wall. We need to know the distance of that horizontal wall, and we can see that inside the laundry room right here. If I look at the handout, I can see that it is ten feet three and a half inches from the interior wall to the interior wall.

Before I make that offset, I'm going to zoom in. Tr, enter. I'll just trim out this so that now we're offsetting only this line.

So let's do our offset. O, enter. That's ten feet three point five, enter.

From inside to inside, enter to say I'm done. Enter to go back in. Six, enter.

Here and up, enter to say I'm done. Now we can fillet this corner. Fillet, here to here, enter to go back in, here to here.

Now we can extend these lines up to those corners, and we can use fillet. F, enter for fillet, here to here, enter to go back in, here to here. Now of course these lines continue past, but we can always use fillet to extend lines as far as they need to go.

So the next offset is for that closet here, and that's from this edge over a total distance of two feet ten inches, and then we'll bring it back six inches. So let's go offset, two feet ten, enter. From here to there, enter to say I'm done.

Enter to go back in. A distance of six, enter. Here to here, enter to say I'm done.

Now let's clean all of this up with fillet and trim. I'll start with fillet, here to here, enter to go back in, here to here. Now this can easily be trimmed.

I'll go T, R, enter, T, R, enter. I'll start by just trimming those ones out the side, and now I can jump in and do quick trims inside all of my wall joins. Enter to say I'm done, control S to save.

The last wall we need to create is this small little piece for the furnace. That offset distance is going to go one feet nine and a half from this edge to the inside over here. Let's go O, enter for offset, one feet nine point five, enter.

Here to here, enter to say I'm done. Enter to go back in, and from the bottom edge here, we need to go down three feet six inches. Three feet six, enter.

Bottom edge down, and click. Now let's do our six inch offset, enter to say I'm done, enter to go back in, six, enter. This line's going to go up, and this line's going to go to the right.

Enter to say I'm done. Let's finish with some trims, T, R, enter. I'll trim out these, then I'll zoom in and get my wall joins.

And finally, you can see that the front of this is open. Now technically, this is a door opening, but we can take care of it right now. First things first, this line needs to go away completely, so I'll hit delete.

And again, we can't use fillet, because if we fillet this, it'll remove the line from the other side. We can do a couple of things here. We can break the line into two lines, and then fillet on each side, or we can simply extend and trim.

I'll quickly show both as examples. If I go modify, break, and this is the break at point. I'll pick my line and break it right here.

Now these are two distinct lines, and I can go fillet, F, enter, this side, and this side. Okay? I'll undo it, and this time, I'll extend and trim. So I'll go extend, this line and this line, enter to say I'm done, T, R, enter to enter into trim, and then I can trim out that line.

Enter to say that I'm done. Please use either option to finish this workflow. I'll do zoom extents, control S to save.

And we've created all of our interior walls, and there's only one more thing we need to do before we create our door and window openings, and that is to add in our fireplace up here. I suggest you open your A202 PDF handout, as it has a zoomed in detail view of the fireplace, and you'll be able to find accurate dimensions from there. I'll see you in the next video.
