Advice? New build preliminary ideas

So I am at the point that I can start some plans towards a new tank build. It is going to be an in wall tank on the main floor. The sump etc will all be in the basement almost directly underneath it. I am thinking it will need to be a standard dimension 125 gallon glass tank. I'd like a 180 but I think the extra depth will interfere with space in the pantry behind it, which is the original intent of the project and would be vetoed by my better half. Anyway, I won't drone on about the pantry details just that plumbing must be self contained within the tank dimensions or on the single end closest to the outside wall as a Herbie overflow weir. Personally I think I'm going to just go the standard corner overflows as I'd prefer that to only using a narrow weir on one end of the tank. I'll have doors above of some type on the front side so I can access the tank both front and back. Anyone that has done an in wall build before have any thoughts. I have a great carpenter helping me with this but he hasn't done any in wall tanks before so is basically relying on me for how I want it done. For your entertainment I have included my sophisticated 2 minute CAD model of what this will look like.

 

Ill have to see about ideas on making the tank hang out the front about 6 inches or so. I dont have a lot of room to work with either side but maybe theres a way. Id like a low profile overflow but I think only having the weir on that one narrow end wouldnt be great for filtration. Maybe Im too concerned about that.

 

So I think the bump out idea will work. Now, I am thinking I want to do an acrylic tank. I've never had one before other than as a sump. If I can find a good priced glass 180 drilled for a bean animal or undrilled that I can get drilled I might consider that. I dont have a strong preference one way or the other but given I'm doing this job mostly alone I think the lighter weight tank is going to make adjustments easier and reduce how much floor reinforcement I do.

 

Oh I thought a glass 180 weighed a lot more than that. Yeah I was planning on reinforcing but that was with me guesstimating a glass tank was closer to 400 lbs. I've got support now for a load of around 1800 lbs but want to be extra sure. Do tuxedo urchins damage acrylic? Because they have eaten all my coraline in my 75 gallon. I suppose the real decider is going to be who can get me a 72x24x24 tank bean animal drilled on one end or undrilled first for the right price.

 

And to be clear I planned on reinforcing the floor, just that since I am close I don't think I need to go nuts with it like I would if it was several hundred pounds heavier than that.
