Yep, it sure adds up doesn't it! It's a lot of money for perhaps not an equivalent amount of value gain. But it's not necessarily the builder's fault or issue here. Their pricing here is not surprising, but to clarify not sure how you can isolate the kitchen or what exactly does 30K mean? Is it joinery only, is it including fittings? Is the balcony upper or main level. The question is, is this actually the best way to spend your money? Considering how much you're spending, should you be considering getting proper value for the money and getting more for your money with potentially a different design?. Are you happy with the design? It's going to be super? Is it worth $400K to you for what you're going to get? If the answer's no then a design rethink is possibly in order. Where are you at in the design/doc process? have you used a drafty, designer, architect to help you with the process? What people often get quite wrong with renovation projects is the distribution of budget in regards to HOW it's being spent (you WILL spend it one way or the other), and it always comes back to the design/layout as to how well or not it's spent. Really need to see actual plans to be able to assess and comment further with more accuracy otherwise just speculating on in all. Depending upon your finishing decisions this sort if thing could easily nudge the $450K mark.

I had polished concrete put in my basement a couple of years ago and it’s held up pretty well. The cost for me ended up being around \$5 a square foot, though that can swing a bit depending on whether you go with a basic matte finish or a higher gloss with stain. I didn’t get too fancy, just a medium gloss, but I’d say the biggest thing is making sure the sealer is done properly, it makes a huge difference in how easy it is to clean and how well it resists marks.

Are you planning floor plan changes or renovation of bathrooms/kitchen or cosmetic/decor refresh? How much help do you want? Having a clear scope, a clear list of wants versus needs, and a clear idea of outcomes will give you the best return on investment. Will also narrow down what category of assistance you need.
