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.

Shutters sound like they would be a great addition to your new almost at the beach house. Is it an open concept? If so while you can change things up a bit you'll want to repeat some element and ensure that everything looks great together. Even the rooms you're thinking of putting drapes in might benefit from shutters or wood blinds for both looks and light/privacy control. Also be aware of how these windows will look from the outside. When choosing fabrics look at your existing furniture for inspiration or a piece of existing art or if buying new furniture think about the windows as you do. Everything in the room ties into each other. Ideally you would have swatches and samples of every finish in the room from flooring to window coverings and everything in between including wall colour, area rugs, bedding ect to help make your final decisions easier.

As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

Get the professional sander guys in to repair the living areas and kitchen but don't go too dark with the stain as it will kill the lovely grain in the matai. I'm thinking a couple of tones richer than the timber knots showing in your photo, definitely no yellow tone at all. In NZ stepping on to carpet especially in a kiwi winter is so much nicer than a cold floor board shock!!! A nice area rug for the lounge and you're done.
