I have a whole wall that I need to block off with some sort of door. I'm thinking that a bi-fold door would be awesome. However, my husband kind of wants a sliding door. I just think how cool it'd be to have a whole wall made up of a door that could easily be tucked away when needed. This would make outdoor barbecues a lot easier. It would sure save me from having to open the door every time. http://www.superiorwindows.com.au/content/Products/BifoldDoors.aspx 

Hi Lesley, I would contact a couple of frameless glass door hardware suppliers like Feathers or C. R. Laurence and see if they have something like a clear plastic clip-on seal with an wide brush seal or fin seal. It might also be worth finding out if there is any adjustment on the door tracks which might be able to bring the sliding doors closer to the fixed panel.

Many many modern builds complain of upstairs being too hot and downstairs being too cold. I think a door is a good idea but I’d couple it with rethinking having one heating/cooling system for the whole house. Speak to an air con professional. Ducted downstairs and splits upstairs maybe more suitable.

I'm not a huge fan of the door. I'm thinking I'd prefer a timber door with glass panels of some description. Our two current couches are light grey but I'd like to replace them with a blue corner one in the near future. TV unit and bookshelf on the back wall are white. The walls in the room will be Dulux White Exchange Half and the skirting boards/trim will be Dulux Snowy Mountains Quarter. I'm unsure about having a medium-dark grey feature wall (either paint or textured wallpaper) for tv unit and tv to be wall mounted on - this is the wall to the left of the shelving in the image. Floorboards will be a bit lighter and more natural in tone - not as orangey as pictured.
