The photo is to feature bench top and table by Timber Revival. Maybe contact them (Website, Facebook or on Houzz) to find out about tiles in the picture? They may be able to tell you, or find out from one of their clients. They really are beautiful tiles.

Consider combining the concept of console with shoe storage. Check out this cabinet for example. http://www.mattblatt.com.au/Credenza-Storage/Bakbo-Tall-Cabinet.aspx?p19566c17#19568 It has a mid century modern feel and comes in both blond and walnut timber. While this style of cabinet is a bit taller than the average console or buffet it is still low enough for a mirror over the top. The advantage is it's a stylish piece of furniture that has shelves for shoes, hidden behind doors. Although the entry/hall is long it is already full of doors so try not to fill it up with furniture. A single cool looking piece of furniture on either walls #1 or #3 with some fabulous artwork on wall #5 and whichever of #1 and #3 doesn't have the cabinet on.

This isn't a personal recommendation as I have not yet purchased anything from this company, but I've been admiring the timber floating shelves on their website. https://shelvingshop.com.au/product-category/floating-shelves/wood-effect-finish/ Or you can buy the brackets and have the shelf custom made in whatever material and size you want. https://shelvingshop.com.au/product-category/brackets-2/floating-shelving-brackets/  I think hardware stores also sell brackets by themselves. I was thinking of going the custom route because that means I can ensure the brackets will be attached to the studs. I believe you can paint melamine after proper preparation of the surface, but I doubt if you can stain it.

my sister had to originally put her washer dryer at one end of the kitchen, european style. She actually found it way more convenient, and so when she got to upgrade and do over the kitchen, one end of the galley became the butlers pantry with washer and dryer in there as well. maybe it could work, but given all the advice above, I think avoiding moving walls is going to be important. Gosh, hopefully everyone's advice helps! Don't worry and take your time, I have been in my old house a year and I think i came up with 4 different floor plans before i realised what I needed to do. keep thinking it over and one day it will just hit you what needs to be done.
