dormer 2nd floor issue


Recommended Posts

client is wanting boys bedroom on 2nd floor. Egress will be thru dormer window after opening door. I cannot get the dormer thru automatice dormer to set in there. 

I would appreciate any help in designing a dormer to set in area landing. 


Thank you if someone can assist me.

I downloaded the plan and had a look at it.  The Ontario Building Code requires that 5% of the floor space in a bedroom be unobstructed window opening.  A window at the end of a hallway, such as in the dormer depicted would not qualify.  I realize that you are not in Ontario, but all building codes have some very similar elements, and I would suggest you look into code requirements before going too far down the design path.  The consequences of building something not code compliant can be very severe if anything goes wrong at a later date, or if the construction is flagged by a building inspector.  Doing work without a building permit often attracts court action by the municipality, if not for the contractor, certainly for the homeowner.    


I am not implying that this is what you are doing, just offering some advice for those who are not familiar with the constraints imposed by building code and the municipalities who administer them.

You did ok as far as ChiefArchitect.


You drew the line for knee wall. And appears to tried to place automated dormer.

The reason it did not generate because it needs to be in the attic. While you declared it the "Attic" room - it is not the attic. Attic room tells CA not to generate drywall, baseboards, etc.



1) Go level UP to the attic

2) Draw same knee wall in the same space using references

3) Hit automated dormer and click in between eaves and your knee wall centered in your space. The dormer should generate just fine.

4) Remove the knee wall in the attic.



As far as codes as long as the door is there it can NOT be a bedroom. (Art and crafts or remove the door?)

You egress has to be more than 20" wide and no more than 44" from the floor.  Thus windows have to be framed at like 40 to be safe.

      The red arrows point to the problem area.
      The outside wall and interior wall at the closet intersect with the valley where the two roof planes intersect.
      The interior of the room creates an attic wall (with exterior siding) above the closet (NOTE: Ceiling was removed to get image)
      The plan view shows where the roof planes intersect at the valley. I have the same problem on the other side of the house because it is symmetrical.
      The plan is too large (65MB) but here is the model (
      Any suggestion on how to fix this would be greatly appreciated.

      This bathroom is upstairs, tucked into a dormer. You can see the adjacent roofs in the mirror reflections.
      Reflections like these can be controlled in the Material Properties, and displayed using camera specifications. PBR views like this one do a good job representing reflections in mirrors, and also reflections on shiny surfaces like counters, porcelain, and even metal. Other benefits of this rendering technique are high quality shadows and lighting, all combined with real-time rendering. This means you can navigation your scenes in front of a client or home owner and it will look as good from each angle.

      You'll notice that floor plan Option 3 and Option 4 for the Paradise Rises project are quite similar. Both are a story and a half with matching structural walls and feature livable attic space. The attic in Option 3 has been left mostly unfinished. This creates an opportunity for a home owner in Paradise, CA, to rebuild a livable space for themselves with cost savings by not immediately finishing the upstairs. Once they are prepared to complete the project, residents to can choose to wrap it up on their own accord.
      Review the full design set to see how the attic spaces differ between architectural styles due to the location and placement of dormers.

      Hi Everyone,
      I am a newbie and using Architectural 2019.  I placed a railing on the outside edge of my front porch and would like to delete it.  But, every time I try to delete it, the roof goes down to the ground on the porch area.  Can anyone help please?
      Thanks, Darlene
