@ hollielambrose...I am of the turn of mind that if somebody just loves things natural and oif "driftwood" or old wood...or even new twigs and branches... and can envision what can be made from those pieces of nondescript nature...these are all very acceptable in any kind of home. I do not like homes that are show pieces in themselves, musoleums to one's existence so to speak, but i definitely do like homes that are turned into artifacts by everything hand made and recycled/repurposed. Thes items have soul! They express the idea of "home...where the heart lives" and the creativity and zest for living and beautiful things of those who have made them or purchased them for their homes. Every one of the Pictures above is an inspiration to me! To me a hand made item from any kind of wood or twig that has been designed to serve a practical purpose is something of wonder compared with some of the stark concrete sleek dwellings that are in vogue today. A HOME never dates. A HOUSE does.

^^ Chalk paint will get the job done. If you're comfortable with DIY then mix up your own, or if not, it's worth going to a specialist store and getting some advice, even just to build your confidence. There are lots of online tutorials for chalk paint as well, so jump on youtube first so you know what you're dealing with. That brick wall could look really great painted, but maybe even better with some panelling over the top.

I've not seen that one in Australia but I'd look at Robert Plumb and Domo furniture. Not sure if Mark Tuckey does an outdoor range but worth a look.

Go with your plan to feature colour Wall A and mount mirror on Wall A and place beachy art work on Wall B. My suggestion is to maybe consider using a paint colour for the featured wall that is tonally similar to paint on Wall B and not too dark so as to give room depth but not close it in with a dark heavy contrasting shade. Offsetting the hanging of the mirror closer (to the plant) could also add interest (and work with the shorter end of the sofa). Often going with you intuition is the best advice!!!
