You should have a professional installer in your area take a look at your home so you can discuss what end result you are wanting. You may need to use an engineered wood. This is still an all wood product and is much more dimensionally stable than solid wood. This is a huge advantage if you are in an older home or in the midwest where humidity levels can drastically change from season to season. A solid wood will cup or curl if humidity and moisture levels are not managed. Your installer should do a moisture test before installation to make sure the installation does not fail. All warranties will be voided if this step is not taken. Also, your transitions will need to be considered. Is the new wood floor going to butt up to tile, carpet, or vinyl? The height difference in the two products will need to be taken into consideration. You will have a greater selection of thicknesses in the engineered woods. Engineered wood should be several plys, all wood. If you choose a solid wood, the hand scraped versions are fantastic for a high traffic area with children. Hickory, Red Oak, most Brazilian Species, and even Bamboo are hard enough to take everyday traffic and still look terrific. Good luck!

I would choose a wide plank, hand hewn product. Many manufacturers out there to choose from. It will hold up much better and should achieve your design your looking for. Good luck!

Your old gold chair color is a bit hard to match with today's color palettes which usually use a softer gold. Have you thought about taking a blue into the dining room? Blue and gold is a very elegant combination and will compliment the mahogany floor and table. You could look for a stripe or a damask for the drapes or a wallpaper that would incorporate your chosen colors. An oriental rug would be a good way to tie in colors.

Your room looks large and lovely but with an entrance at one end and a fireplace at the other can seem a bit long. Firstly take EVERYTHING out. This will show the room in the best advantage and get rid of clutter. Only put back things you absolutely love. I would put two sofas or a sofa and two chairs (they don't have to be a suite) in front of the fireplace OR get a solid coloured L shaped sofa as it seems you are orienting the room toward the TV. You could then put a nice rug under a light-feeling coffee table (maybe glass and wood to pick up your chimney breast) in the middle. This would allow you to get rid of the multiple small side tables. I would lighten up the alcoves alongside the fireplace, either paint or light wallpaper. Get a proper piece of furniture for the TV to stand on. TV stands are ugly. There's lots to choose from. Try IKEA. Take down the heavy curtains and put in Roman blinds in a print fabric you love (try to find one with at least 3 colours) and coordinate with your rug. You could then use colours in this to make/pick throws and pillows. At the end near the door you could put in a small table and your rocking chair and make it like a separate area for music or reading with a nice standing lamp. Get some inexpensive drum light shades to update the lighting and put in another standing lamp by your sofa, as mentioned above, and lower your pictures to eye height. Good luck!
