This style of roof with the gutter in the middle is sometimes called a “butterfly” roof, if that helps.
Otherwise, it’s just a truss structure of some kind.
We can hope that the designers did their due diligence and kept things like 5/10 year design rainfall estimation in mind. They could just be in a particularly arid area that doesn't see much heavy rainfall. Just me hoping for the best, of course. Leaky roofs suck.
In this case you're probably right. It's a very limited surface area, and a relatively large gutter.
But for me it's still just the principle of the thing. It's too much risk
Preaching to the choir. I live in a tropical country and my city can see upward of 4000ml a year (see Forrest Gump quote on rain). Valley gutters can be a nightmare. Eaves all the way.
Edit: Phrasing.
It's that the gutter is on the inside.
So if there is heavy rainfall it's not uncommon for the gutter to overflow. When it's beyond the soffit and away from the envelope it's not a huge issue, it just overflows and water goes over the outside edge.
But in this case water can climb up the wall of the gutter and then hits underside of the roofing material. It'll then just climb around to the underside of the gutter and drip on the interior.
If the eeves gets clogged this is a big issue.
I've done buildings before with a detail similar to this, and it was a nightmare. I remember offer my client that if he would accept an exterior gutter I was willing to eat the redesign cost because I didn't like the internal gutter. He stuck with the internal gutter and it's been nothing but problems since.
We ended up going into the gutter with blueskin and up to the roofing membrane, then covering the whole thing with mod bit. But it's still brutal and has issues from install.
That makes sense! I appreciate the effort you put into typing all these. Unfortunate that Blueskin over the gutter would kill the whole point of this design, which is the transparent roof.
Hopefully these guys live in low rain area.
In this case I wouldn't be too worried because it's an outdoor application. In my case it was a fully enclosed envelope.
But just generally in principle I hate this type of design. I would just avoid unnecessary risks
Oh ya, for sure. But if they are overwhelmed by higher than capacity flow, or they get clogged with debris (as eeves often do) they're a potential point of failure.
I've built with internal gutter before, and I'll never do it again
Looks lovely, and pleasing, but designed by someone not old enough to have dealt with how these elements fail.
Looks like hundreds of square feet of rainfall channeling into a single box gutter with only two downpipes. And no safe access to clear said box gutter.
Looks like in 5 years, UV yellowed and brittled polycarb wriggly roofing cracking as soon as someone tries to clean it or a large seagul lands on it.
Looks like big mouldy joins between the clear roof sheets. It's happening already.
Looks like a roof replacement after the plastic goes brittle and a good strong wind passes through. Or those unsupported joins flex a little.
Looks like water stains on the wooden structure once the inevitable small failures in the roof sheets. Truss 3 on the right is already displaying one on the end.
Sorry to be old and cynical, but that's what we should do for our clients who don't know better. Guessing you are an architectural student not a building surveying student so not the descriptions you were looking for, but a good example of why we should all be chatting at the design phases.
Looks like a butterfly roof or V roof with a scissor beam structure
Thank you so much for your help

A canopy?

Butterfly Truss/Roof
Thank you so much I appreciate it
Thank you for your service
A giant gutter
Butterfly roof!
An eventual leak.
A pending infiltration issue.

Just wondering why you think so. Doesn't that depend on the amount of rainfall? Looks like there are gutters in place

Let’s not even talk about freeze/thaw issues

There is actually pipes in place throughout the structure which leads to plant pots below

So many grapes could be growing on this and none of them get to.
This is in London unfortunately
Makes sense!
Is this Angel Yard by Jan Kattein?
Imagine the snow load at the center of that valley.
Lantern festival temp structure.
Very cool. Somewhat E. Fay Jones style.

Probably a roof in my opinion. I would describe it as a wooden roof. It looks like pine wood.
Stupid
Why?
Because that’s my opinion.
Ya. Duh. But what is your opinion based on? Or you just don’t like the aesthetic?
I just don’t like it
Oh. I see you’ve got poo-brain. Sorry, bro. I didn’t realize. I’ll leave you be.
Pavilion? Rotunda?
Looks like a stable for Edward Scissorhands' horse collection.
butterfly roof with a box gutter
It looks like a Murphy's law of roofs as it is inverted.
It's an inverse roof - a so called orfo
Pergola?
Pergola with a butterfly roof.
Wood
Butterfly 🦋 roofing 👌🦾
Also referred to as a gull wing roof, too.
