I would suggest your plumber links the hot and cold fill pipes to the supply UNDER the sink - this gets rid of unsightly pipes and while he's there get him to move the taps to the L side of sink. I would then create a broad drop down counter top to create a place to sort your laundry ready for hanging out to dry or to fold ready for ironing This drop down counter top to be hinged to R side of washing machine and ensuring the taps are not impeded. If you can't do the drop down version then create a free standing top made out of a piece of MDF/laminated board to put over the sink and washing machine for clothes sorting & folding. This free standing top can 'live' at the side of the washing machine when not needed. I would then put shelves above the folded back counter top to store washing powder and sundries. I would store the washing powder etc in colourful or white boxes to keep the place looking tidy and uniform. Handles on the boxes for ease of access. Oh I do love organising - can I pop round and do this for you? Hope all goes well with the changes.

How about butcher block instead? IKEA and the big box stores sell it for countertops, the price is decent, and you won't have as many issues with buckling, water damage, or what to do with the edge as you would with the ply. If the edges of the ply get wet, or if any seam around a sink gets wet, the plywood will "blow" and you will have to replace it all, anyway.

Lighting - pendants over the servery bench should be another feature that complements your chosen kitchen surfaces. So whilst I love the copper pendants in picture 1.. They could work depending on the rest of your decor and would be a highlight in a neutral white/timber kitchen = Good! If you choose copper you would complement it with a couple of copper bench top items. These are beautiful! (I collect copper because I love it, my kitchen pendants are silver, I renovated to sell in the next 3-5 years) You will see a picture starting to form in your mind and there is nothing wrong with making a statement with your lighting. I found that when I wasn't sure I would get a very strong sense of what was right and what was wrong for a space, then common sense or passion would determine the outcome! Here are another couple that might work, look her on Houzz under lighting, search pendants, then have fun looking!Timber tones with black or white to complement your cabinets... or Statement white pendants for a bit of quirky fun! Your personality can be reflected in your lighting and accessories creating that point of difference from the predictable white on timber look. Plus don't forget the power of greenery to punctuate the theme!

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.
