Looks about right to me but your builder will have taken more detailed measurements.

If I were building it I would consider going "double oversize" on the tubes to achieve required stiffness given your relatively high weight and that it's a large frame.

I would also make the seat tube longer (and the top tube closer to horizontal) so you have less seatpost sticking out. (Unless you want a dropper post). It's fashionable to have a lot of seat post sticking out nowadays,.and it gives you a bit of suspension, but it puts a lot of strain on the top of the seat tube especially with a heavier rider. It will probably be absolutely fine I'm just sharing my thinking here! Maybe some things to discuss with the builder.
