Bay window floor joints - opposite way to cantilever

[cascas]

I have a bay window with upstairs bay above.

Usually I would extend upstairs joists out into the bay to cantilever the floor out. In this case the main house joists run the opposite way (across the bay, not into the bay)

How should the joists/floor be framed into the bay area in this instance.

New build or existing?
What supports the bay walls?

 

[cascas]

Existing. Bay walls are timber framed secured to floor joists.

Im still not 100% with you.. was there not floor there previously?
Actually im only about 20% with you.. may need a sketch or photos.

This is quite common.

The floor has little load, but the main bay relies on support from the frame below and fixings to the main house walls

Hi,

apologies in advance for my sketching skills (or lack of)

The bottom diagram is from outside. The vertical studs of the wall under the stairs window do not rest on anything.
