I think you could get the telly put over the fireplace. Might need a mantle to deflect radiant heat, not sure. But on the cables and power, I imagine they can get that sorted. Im guessing there is a wall behind you when you took the photos. I agree that a low corner modular sofa would look great. Just don't get it so long that it is up against the fireplace wall. Placed into that corner of end and piano walls . Then pop your cute chair where the sofa is now. Large ( big enough for the sofa front legs sit on it, I'm guessing 2x3m or even 3x4m) patterned rug to define the area. Can you move the piano to another room or against the computer area wall? Can you make the small windowed room the homework hub? Imagine a long bench against the window ( Ikea do a good cheap range that you make to fit your space). Ensuring the computers are in line of sight from the kitchen(?). Pull out the table to give it more space around it. Or flip it to run the other direction. Hard to tell from the pics the dimensions. Paint a lighter shade as mentioned before. A sketch of your floorplan would be really helpful :)

Hi there! Is this photo from Houzz? If so, you can ask a question directly on the photo and the professional who has uploaded it will get notified and hopefully be able to give you some answers :)

We used Bunnings flat pack shelving in one of our walk in wardrobes, I'm pretty sure it is Melamine and it is fine. There have been a lot of advances and improvements to these products over the years and they aren't the cheap nasties they used to be. Ours are a matte finish too so look much nicer and classier than a gloss. Have you asked the joiner for a sample of just what he is thinking? This should give you a good idea. Check out Bunnings flat pack products too. You could use just an MDF and paint it, but that is more work and the paint can chip or wear off on shelves. Unless you want to go to the expense of having all solid timber, you will find most products are MDF coated with a timber veneer or a product like Melamine. Going on what I have, and I know Melamine was used internally in my new kitchen cupboards, I don't think you will have any problems. If you are having shelving, do ensure you use adjustable shelving too - it is such a bonus in areas like this when your needs can change over the years and it is so easy to just add or subtract shelves or adjust the height. The wire systems are OK for some things but over the years the plastic coating cracks and breaks off and you could then have difficulty replacing the baskets. You are also more restricted with sizes.

Looking for advice of what the best dark colour (Matt finish) we could use for kitchen cabinets that would go well with a Black galaxy granite benchtop (black with bronze flakes through it). Thanks
