Gate construction

[adlib]

Hello!
We are considering building a gate for our backyard. The plan is for a gate extending from our shed (the white building to the left in the picture) to the gatepost you can glimpse in the hedge (to the right in the picture). You can naturally deduce the previous gate placement from the two posts, but we now want to create an "enclosure" for our cats, making the current intended opening the "easiest" to close.

The measurement from the corner of the shed to the gatepost is just over 140 cm, which makes the opening relatively wide. My plan is a gate similar to the one seen in the drawing, with approximate dimensions of 210x140 cm. The idea is to build the frame from 45x70 mm studs and reinforce the crossbeam with metal plates, like corner irons for corner constructions.
Furthermore, I then plan to chamfer the upper and lower edges (marked A and B) with a 15-20° angle so that rainwater doesn't remain on the construction.
Finally, the construction will be painted with the housing association's "outdoor paint," which is some acrylic variant if I remember correctly, and then net the frame with some strong variant of netting. We would like to have netting so that the wind resistance isn't too large and to see through.

Of course, the whole thing then needs to be attached to the wall... what's the most suitable way to do this? Hinges, I understand, but is there any specific kind recommended in this case, as the construction is fairly wide? Should more hinges be used to compensate? Since the frame of the gate itself isn't particularly wide, it's difficult to attach longer hinges, but perhaps long ones aren't necessary?

Any feedback and thoughts are welcome!
Thanks in advance!

Hello!
We are considering building a gate for our backyard. The plan is a gate that extends from our storage shed (the white building on the left in the picture) to the gatepost you can glimpse in the hedge (on the right in the picture). The previous gate location can naturally be deduced from the two posts, but now we want to create an "enclosure" for our cats, which makes the currently considered opening the "easiest" to close.

My plan is a gate similar to the one you can see in the drawing, with approximate dimensions of 210x140 cm. The idea is to build the frame from 45x70 mm studs and reinforce the crossbar with gusset plates, such as angle irons for the corner constructions.
Furthermore, I then thought of beveling the upper and lower edges (marked A and B) with a 15-20° angle so that rainwater does not stand on the construction.
Finally, the structure will be painted with the association's "outdoor paint," which is some acrylic variant if I remember correctly, and then mesh the frame with some strong type of netting. We would like to use netting so that the wind resistance doesn't become too great and so one can see through.

Of course, the whole thing then needs to be attached to the wall… what is the best way to do that? I understand hinges, but is there a specific variant recommended in this case, since the construction is quite wide? Should we have more hinges to compensate?

Three heavier hinges will be just fine, I feel spontaneously. The weight is quite low despite the width.
