Let's keep it nice, I don't think EthanWes is as precious as you may think and it is a forum for personal opinions after all. I also thought the comeback was unnecessarily aggressive & unwarranted. I would keep whatever you put there quite subtle and simple in colour so it doesn't draw the eye. You've got a nice retro/scandi feel from the look of it, see it as another way to carry this through?! So some ideas: - a small succulent in a low 1-2" pot, possibly including a trailing one such as Silver Falls (though don't let it get too out of hand!), will help make it look less compartmenty. Or even Ikea http://www.ikea.com/au/en/catalog/products/40349079/ - a couple of neutral coloured cookbooks stacked horizontally. - a nice low serving dish in a soft grey - but make it one you will actually use, not just for aesthetics! ; D I have a similar one to this https://www.countryroad.com.au/shop/home/kitchen-and-dining/serving/60209668/Tiro-Salad-Bowl.html https://www.countryroad.com.au/shop/home/kitchen-and-dining/serving/60203911-9084/Tapas-Salad-Bowl.html and use it a lot. - or, if you like your tech, it could be a great place for a small wireless speaker. Expensive example, but something like the Bose Soundlink Mini If you're looking for more ideas, 'open shelving' should provide lots though you are constrained with the very low height of the shelves.

Can I suggest that as most of your proposed project comes under the umbrella of landscaping that you consult an experienced landscape designer in the first instance. Someone who is experienced with pools and outdoor rooms. Also someone who has a network of other professionals that they work with such as pool builders, architect or architectural designer and engineers that may be necessary for the permits and build once the overall conceptual design is realized. All of your wish list will need to flow together and be cohesive to function well and a good designer will be able to work with your design brief and guide you through this first stage which is critical if you intent to carry the work out in stages. All the very best with your project. Lynn

They may have shaped the end of the exposed ceiling joists to imitate a decorative add-on known as dentils, which are popular in the UK. They are small shaped blocks attached to the soffit/ eaves and are usually made of wood, GRP or polymer. https://www.canopyproducts.co.uk/shop/dentils/ The effect can also be replicated in brickwork, stonework and plaster, etc.
