Patio--assume not too high of ground. If high, then rules requiring strong railings apply. In any case, Aluminum railings will have narrower posts than Vinyl as well as narrower railings. This could be extremely sturdy if extended railings could be inserted as the cement is poured, but can be done by using cement anchor bolts on a flange plated posts if being done after the fact. Some of the railing types have very thin posts. These are acceptable for a patio within a few feet of the ground, but I would use 2"+ posts on a tall raised deck. I would want at least either a thin post every six feet with a "leg" extender railing between each post or a post every five feet. (definitions: extender post two screws, real flanged post, 4 corner bolts into base) No form of railing is strong enough for that long a span without serious anchor points in between. Gates require anchors at both sides so this and end posts is enough for short direction if gates not too close to corner, but long direction needs some support.

you need to work with a pro who has a little creativity because your objections really shouldn't be a big deal. To keep the p/t lumber from being visible, use a stainless steel grommet in the ipe post trim with a hole bigger than the one holding the cable in the p/t post. for the cap rail, do a metal cap rail to meet code, then router a channel in the ipe and mount it to that. Done. It'll take a little bit of design time to ensure that all your proportions are right and everything ties together appropriately and structurally, but there are definitely ways to get the look you want while satisfying the permit store. Obviously not dimensionally accurate or really thought through in terms of attachments, but here's the gist.

I hate the posts were removed as there was something I wanted to reply to. I don't remember what was posted! LOL I do know it was mentioned about door chimes. We have an alarm system and we have door chimes. We leave ours off as it is just the two of us and no need, but if you needed to know if someone was leaving the house, it's a good option. Also, my dad had a pendant when he was in assisted living. He could, of course, call for help if he needed it, but they could also keep track of where he was with the pendant. We have another relative using one now. Really, this type spamming does not bother me. Sometimes it's actually nice to have some of the old threads revived. Otherwise, I just ignore the spammer.

IMHO, this does not look good at all. I would not except this solution. It looks like you just slapped up a piece of molding. It needs to be integrated more with the existing chair rail and base molding. If you move it over to start under the chair rail, it would be too close to the boxed out trim. If you want it to look like it is meant to be this way, he really needs to move the trim under the chair rail and shorten the width of the box so the spacing is the same as the distance between other boxes. Also, the trim piece should not stand proud of the base piece. You need someone that knows how to rework this to look professional.
