how to frame a deck around a bay window?


There's LOT'S of examples of how to frame around a bay widow. However, NONE of the examples offer insight on how to frame around an ANGLED bay window, which, is what most bay windows are! Aside from the obvious use of skewed joist hangers, which aren't allowed with local code, how does one frame around and angled bay window and keep load ratings for the deck surface between the bay window and the "normal" frame? Thanks.

Cut the bay structure out under the window. Attach the ledger to the house and rebuild the bay to the deck.
Support as needed.

how to frame a deck around a bay window?


interesting...but the bay is cantilevered, and the beam sits below the top deck height. No cutting going on there...

Post a picture of the structure you have. Any bay can be restructured.

Fig. 35, add an angled joist to cut the corner with hangers: http://www.lancova.com/deckinfo.pdf

Not sure what the rules/laws are where you're at. But couldn't you frame the deck w/ your joists sitting on top of a twin 2x beam. Locate your beam at the face of the bay, then cantilever the joists the 2' or so back to the house? Work around the bay rather than reconstruct it. I'll come up with a sketch and post it if need be.

That can't be true. Never heard of such a thing before.

How wide is the bay?

Couldn't you frame around the bay window similar to how you would frame an opening in the floor for stairs? Double up on the joists adjacent to the window & connect them with another doubled up header to attach the joists in front of the window to.

Sorry for the crude sketch, but I think it'll clarify what I mean.

how to frame a deck around a bay window?


regarding the diagram shown in the last post, how would I attach decking material past the 2 2byX up to the window? I believe code allows 2" of decking to extend past a frame member? In my configuration, after installing the H frame around the bay, I'll have a 20" gap at the widest part of the triangle. The H Frame makes sense, I'm just wrestling with the angled frame members: I can find now skewed hangers that will work at the angles I have to work with. The simpson is only good for 40-50 and I'm at 30(L) and 60(R).

Just run some joists on an angle to close the space (mirror the bay window angle).

What's the problem then? You said code won't allow skewed hangers, now the code will allow? This is normal every day framing with bays and skewed hangers. I don't understand what problem you are having.
