Very interesting.

What a lovely room you have. My first thought is to establish where your traffic area is. Each room has a natural traffic flow and you will find it frustrating if you have to divert around furniture. Breaking the room up into zones, i.e. tv watching, play space, dining area etc will make the room feel larger and you will use the space more efficiently. When it comes to tv placement, consider where the light comes in. You will want the screen placed where the light from windows won't fall on it, or where you can close a curtain. Also, whether you want to see the tv from the kitchen, or see the view the same time as watching tv. Consider if you want the space to be a conversation area, where the tv doesn't dominate, or be a dedicated tv watching space. There is a lot to think about and decisions will be based on your family's lifestyle. As for furniture, Ikea have some great items suitable for children and toy storage that are reasonably priced. For the lounge, choose the best you can afford, for the sake of comfort. Try getting one with washable slip covers. The same goes for the rug. A good quality wool rug will last a long time, comes up well with cleaning and can even be redyed at a later stage.

Hi J E, This is a common dilemma. Is there any chance you could view the tile under the light you are proposing to use? You have mentioned you are using White LED downlights. Do you know what colour rendering the LED downlights are going to be (eg: 3000k, 4000k, 5000k)? If your builder is specifying the lights then it would be to your advantage to ask to borrow one prior to installation. They usually have a plug on them, which means you could plug it in to a normal power point and view your tile beneath it. You may want to ask for different colour rendering options also so that you get exactly what you want. Hope this helps :)
