Engineeered retaining wall - ~10 feet high

Hi All,
We are about to purchase a house and requested an estimation on extra work required from the builder. The house, as is, has very small yard and we wish to have a bigger yard, leveled with the current small yard, and plan to use an engineered retaining wall in order to achieve this goal. The builder has plenty of excavated land/gravel to fill in the planned yard, basically from a neighbour lot.
We don't have the exact measurements , but based on the lot size - the wall will be around 100 feet long, and 10 feet high, more or less.
The estimation was shared with us and was also added to the overall house price. It is $35000, and seem outrageously high to us. The sales manager claims this is a risk, since the actual estimation might be higher, and he will also need to pay his engineer around 3K for certification.
Since additional lots have the same problem, the builder has done it before. I am attaching a picture similar to what the neighbours have in place.
Please help me to understand if the price is correct, and how complicated is it to do it ourselves after purchase - the permits, the fill, and the headache.
Really appreciate your help, Thank you!
Sam

Go with terraces and multiple walls, and space for plantings, even if it is just 'Pompas Grass'... terraces have a better safety margin and looks much better than a huge wall of stone, brick or concrete...

Depending on exact measurements this doesn't sound outrageous to me. Be careful, that is not a homeowner project. Geo grid, drainage, engineering etc.
good luck with it, remember your lowest price is normally not your best decision!

That's a good price. You don't want to try that on your own

I would prefer this solution, but since this is the only place the kids will be able to roam outside - need a flat surface. Might consider later to cover the wall itself, or incorporate it in somekind of a green design, but do need the leveled wide yard...

Thank you for your advice!

Completely agree this is not a homeowner project, thank you for your advice!
Since the builder is doing the work / builder's subcontractors, etc , and they have the access to all the filling materials -didn't expect such an uptick in price...
Thank you!
Quan

Quan, the heavy costs are in the wall materials and labor not the fill . I understand your sticker shock, we experience that with pretty much all new customers when I ask what they have budgeted for stone work and their proposal from us is significantly higher.
Good luck with the project.

A $35,000.00 play yard for kids,,, because they shouldn't have to play on a slope... an interestting idea,,, might be that the existing hillside would cause children to develop muscle tissue...
Of course the little butterballs are more likely to 'bounce' after a 10' drop-off, so I can see how this wall would be a 'safety feature'...

Smallaxe raises a good point. I hope the installer has a fence built into the price, because when one of the kids go long, they could take a heck of a header off the wall
