Build deck on first floor roof

[Mechanic724]

I'm trying to build a deck over the garage and first floor bump out which both would be a flat platform roof. I cannot seem to figure out how to generate this. Has anyone out there done this before?

 

Thanks for nay help,

Mark

It depends on what you are calling a deck. How will it be built? What will it look like?

Thanks for the help! Added signature, Home Designer Pro 2021 is what I just starting using this past week. I haven't been able to design the platform over the structures as of yet, so you have to imagine that I want a platform over the garage, for example, that would be second floor "base" so as not to confuse terms. I would imagine 2x12' floor joist that would tie into the existing house. On that same level, I would imagine that I would need some type of rubber roofing with a slight pitch to drain water. Within that area, I want and outdoor living area, so decking and railing around the perimeter. I should be able to change the 6" ceiling joist that are there now with a second floor platform. If I could create a second floor over specific areas with railings and no roof, that would go a long way for me. In the original attached image I sent, the "platform" goes over the places where the 6" ceiling joist are.

Is this an existing house you are adding to, or all new construction?

 

Do you need construction documents or is this just for visualization?

You already have a 2nd floor, so draw railing walls to define your deck -- just don't set the Room Type to Deck. Turn off the roof of the resulting rooms.

Yes, this is an existing house that I am planning to add onto, and put a crawlspace foundation in. It's on piers now. I will need construction documents as I will need to get some engineering done for the concrete contractor, as well, I'll need to have doc's for the city as well.

 

I did try to draw railings, but for some reason, they weren't showing up in my 3D view. Settings?

Did they show in Plan? When in a 3D view, did you check Layer Display settings to make sure railing walls are set to display?

 

You should decide on the level of detail you need for your roof top deck -- that is, once you have decided on how it will be built, then you can build the model to reflect this. 

 

Or, you may decide that drawing details using the CAD tools will work, and use the model for a visual representation, and not necessarily show accurate structure.

Thanks Eric, I did end up being able to design what I wanted by deleting the default ceiling joist over the garage and bump out and using the framing tools to place the proper joist. Then using exterior wall and specifying railings with no roof or ceiling.

 

I do actually want the all the framing details as I'll be framing the additions and hip roof myself after the foundation is in. The Designer Pro software is really helpful in playing "what if" scenarios which I went through quit a few, and most likely have more.

 

Next challenge will be making drawings I can send out to the concrete contractors for quotes.

 

Thanks for your help, and attached is a screen shot of where I was going.
