I love your outside entertaining area. It does need a color that would complement but give the area a focal point. I like the darker red,orange colors you may find in natural. You could dress up the table with accessories and place cushions in a complimentary color on the benches. Colored potting containers would also bring it all together. I like the uplighting here in the photo you could place along the back fence to add drama. Your area reminds me of Modern mediterranean landscaping.

Try wood and glass. Consider hanging the mirror vertically and about 5" from the sideboard top. You could also move the table under the light fixture, change it out for a chandelier, and put the sideboard and mirror on the clock wall where the mirror could double the chandy which should hang 36" or less above the table top.

Awesome Houzzers, thanks for the responses. Overwhelming consensus seems to be that they dont work (at least without distressing the table, which sounds complicated). I am now thinking maybe I move the sofa upstairs and buy it a new coffee table along the lines suggested by maureen and lee lee (thanks). In the living room, I could then leave the oak coffee table, together with the armchair that works with it (it has a similar oak frame and is covered in natural linen). Then I can find a new sofa to match the coffee table. Any tips? The coffee table is 1200 x 1200mm. You guys seem to think that is ginormous - how big would the sofa need to be to look proportional? I am thinking of an L shaped sectional. Possibly also in some kind of natural linen fabric? The living room is big (5m x 8m?). Thanks again - much appreciated!

You can of course have a furniture repair business add material and refinish. Or you can add a center accent piece of tile, or wood inlay. If you're going from a narrow rectangle to a square, you would need to disassemble the table anyway, might as well do something fun with it.
