甲板改造

i want to redo my deck to build an outdoor kitchen with bluestone. I'd like for the stair case and corners posts to be grey stacked ledge stone. i'd ideally like for the deck to be plastic lumber so it wont age or need to be stained. i'd like for the deck to be light grey. In addition, i'd like for large storage bins to be on a track under the deck so i can store my outdoor furniture in the winter. ideally access would be on the left side. on The left side of the deck i'd like to have a white wood pergola that comes out from the bedroom above it to provide shade for the outdoor kitchen (built in stone bbq, sink and TV). The pergola would jut out from under the existing triple windows that i'd like to be french doors and a small balcony before the pergola starts.

Under the pergola i'd like to have a built in bench seating that hugs the railing of the deck.

i'd like for the posts to be stacked ledge stone in the main corners.

I'd like for the middle windows in the middle of the ground floor to become a passthrough window to the kitchen inside and for the current single door to be a sliding door.

All the way on the right side of the photo is a chimney between two large windows. on the back of the chimney i'd like to install a 1/2 bath that is accessible only from the outside.

Between the existing deck and the 1/2 bath i'd for a blue stone path and a fire pit.

The deck is 34 by 14.

i've included a real picture as well as rough drawing I did on my own explaining everything. Thanks. While the picture is included please know the house is now battleship grey with white trim. i want something durable and beautiful. thanks.
