Like you said, you obviously have a light issue in the room due to the addition of the corner ceiling light and the need for sheers. Maybe paint the ceiling white. Definitely replace sheers with white plantation shutters and add your beautiful chosen pendant lights over the table. As the table is long maybe you can have the light above the window (and if there is a third one further along) moved in to have them over the table. If the pendant is very large have only one or two and remove the extra light/s altogether. You could also possibly add two wall sconces to the wall opposite the windows depending on the overall room. If you physically can't electrically fit lights on the walls now consider battery candles in the glass flutes. This would give lovely mood lighting. Have the white plantation shutters with no additional curtains but have a very large striped rug either the same red as in your photo with creamy beige to blend with lighter wall; or a light blue and white/ creamy beige rug. The light blue stripe would give a relaxed sense to the room. You may need to have these rugs made up. On the table, change to a larger silver tray and look to improving its content holders to silver and glass, light blue china and one low wide rounded fresh flower vase in silver. For dinner, remove your tall vase of roses and replace with a couple of large glass fluted candle holders with silver base rims with pillar candles either side of the tray. Best wishes.

Well, it has been a long (and sometimes painful) process but we are nearly at the end of the extension/renovation. We ended up going with a building designer (Dalecki Design) who made a few changes we really hadn't considered (including moving the existing bathroom) which may have cost slightly more but completely changed and improved the master bedroom space. Without the pool it will be close to the upper end of our original budget but still within what we were hoping for so fairly happy with that. Overall the new living area is amazing and filled with light compared to the old design. Will throw in some photo updates once we have finally converted the front yard from a sand pit and finished off the driveway, garage door and fencing.

I also like mixed timbers, it can look very stylish, particularly you don't want your furniture the same timber as your floor, we had a lot of jarrah and mahogany timber furniture in our last house with light bamboo floors, I loved it. In this house we have jarrah boards on the floor and with all our dark wood furniture it looked dark and austere, so I have painted some of the furniture and on sold the antiques (I felt would be a crime to paint) and I have also purchased some sofas with light oak waxed legs to go on my jarrah floors in the room my favourite mahogany furniture is still with us. I am loving how it is coming together ..work in progress

The renovation is calming in comparison to previous kitchen. The colours of kitchen and the flooring will definitely last the test of time. Well done to you and your clients.
