Parapet Wall w/ Overhang 1

[Afullilove]

I was wondering what the constructibility would be on something like this in the sketch. I have a concept for a building with a parapet wall at the front which includes an accent overhang of 2-3'. I've seen this look in many modern projects but its usually tied to the main structure of the building. Would this be possible with traditional stick or metal framing? Thanks

...but its usually tied to the main structure of the building.

That would be an important consideration for me considering that:

1) This thing is going to catch wind as though it were designed for that purpose.

2) Wind on this thing has the potential to vibrate the main building and annoy its occupants.

3) In light frame wood, I'd have to think that this thing would need to be tied to the main building for stability.

4) With the main building roof lower than the parapet -- and sloped relative to it -- tying to it laterally could be complex. Maybe cantilevered posts strapped into roof drag struts etc.

I would like for the parapet wall thing to be either self supporting or of a lateral stiffness competitive with that of the main building. And that is a feat that I suspect would be easier to accomplish with hot rolled steel, mass timber, or concrete.

Concrete would actually be my preference for this. It would have excellent lateral stiffness and might be sellable based on it's ability to produce a very thin eyebrow element. That said, I recognize that selling above grade concrete on non-concrete buildings is somewhere between difficult and impossible.

OP, your last sketch is exactly what I was trying to show. The intention is for the posts all to be located within the walls shown in the sketch at the top.

The points about wind loads and connecting to the main building are definitely valid. I was merely trying to show a gravity system which could work with stick framing. I’ve used similar framing for residential projects with architectural features like this.
