Hi,
We are on the top two floors of a non-landmarked brownstone and I am considering having a balcony built on the back of the building. There is a lovely view and it would be great to have a place to sit. There are a couple of huge back windows on the back of the building.
Not sure if this is even doable and feel free to tell me if this is a complete waste of time!
The idea is to possibly later add stairs from the balcony leading up to the roof.
What sort of balcony could be built?
Thanks 🙂
CobbleHiller has a terrific one several floors up on her building so it’s doable.
You would more than likely want to do this out of steel. It could be hung from the building. Would need to see it to say more.

Thanks Dave, might be a daft question, but when you say posts to the ground, do you mean all the way down from our top floor to the ground?
Also, does anybody have an idea of a ballpark number for this sort of thing?
Cheers.
The rule of thumb for a cantilevered balcony is that the joists have to be sistered to the interior building joists 2x the depth of the balconey. You can also do a balconey with a ledger bolted to the building but that requires posts to the ground (and three feet footings). Anything is possible…I’ll let the engineers add to this or correct it.
