Trixee's Passive Solar Build Perth

What windows are getting the translucent laminated glazing? Ours was less than that by far. But it was also separate as we had all our windows laminated and the bathroom type windows upgraded to translucent.

Some of the upgrade quotes I've received so far. These are all E/O. Do they sound reasonable?

Boring stuff:
3-phase power for induction cooktop: $345
Additional soakwell: $1133
8m of Strip drains for alfresco and garage: $1080 (for black plastic) up to $3655 for fancy stainless steel

Exterior:
Porch hardstand: $1260 (still don't know if we want to deck or tile here)
Obscure glazing upgrade to laminated translucence: $1150
Glosswood porch ceiling: $2120 (this was supposed to have been included in initial contract but it slipped our minds and so we forgot to include it! Managed to remember the alfresco, but forgot about the porch )

Doors:
Gainsborough Enchant door handle throughout = Extra $25 each x 13 internal pull doors = $325
Omni Trilock with pull handle for front door = $454 each x 2 handles required = $908
Corinthian Deco internal doors. = $83 each x 11 internal = $913
Corinthian Deco Solid door (internal/garage) = $111 x 2 = $222
Frames upgrade to square edge: $434

Wet areas:
Floor wastes to Bermuda tile insert: $345

Is the quote for obscure to toughened translucent for bathrooms or other HIGE windows? I put in a large bathroom window and changed both ensuite and bathroom to clear for $60 or there abouts!!
