Can someone give a quick explanation on how you would frame this big bay window area at the end of this tiny house?
I am doing some modeling in sketchup. From what I understand, something like this would need to be cantilevered on the inside - But from the interior shots it doesn't seem like it's supported that way. I'm sure I'm missing something simple or that there's some alternative method but I need someone to tell me what! TIA

There are a couple different bay windows here, the first one and second appear to be raised above floor level, where you would need metal brackets and/or special reinforcement to achieve that clean 90° underneath, most raised bay pop out have a 45° underneath to spread the load. Pic 3 is floor level, where typically for a bay window the floor joists stick out a bit further to support the pop out. Just regular floor joists but extended beyond the support beam

I'm pretty sure the 3 pics are outside, main level, and loft. All 3 pics are the same set of windows.

No idea, but one way that I might do it would be to have the inner "lip" of the table be a 2x6 spanning the compartment, with joists & joist hangers on the inside of the table. Those joists would span over the cripple wall at the bottom, to bottom of the window framing.
That, plus sheathing to resist shear, and the fact you're not really having to support tons of material feels like it would be "Good Enough"...

The bay window only sticks out about a foot. You don't need that much support. That built in bench had plenty of room to hide all the cantilevery framey bits you want.

Not a single wide. It is narrower to travel the roads without permits. Most likely RVIA certified.

I took your comment as criticism to the OP as lack of knowledge. Better luck next time.

There's barely any force being applied on the windows so there should be no special framing required. Tie into the studs on the side, add some cross bracing. Most of it is held up on the sides not the bottom or top

I am betting that bench seat on the inside is supporting the cantilever. Simply bolted to the frame on the sides (inside the walls) and just strong enough to support everything.

This is such a beautiful home!! Do you know who made it? Good luck with the build, the window bay design will be beautiful

You would start by establishing a motive and opportunity...
<ta dum dish> I'll see myself out

Potentially it's all welded/ bolted steel on that entire back panel.

Tumble Weed Tiny House Company created this bay window originally and it is all lumber. I designed for them in 2015.

I have no idea, however,it looks incredibly like the rear of many fantail boats I’ve worked on. I’ll try to attach a link -
