paint the end door a striking colour, horizontal stripes on the ceiling, and 3 large pendant lights. not sure how adventurous you are, but you could consider painting different colour "zones"- 3 different colurs as you walk down the passage.....possibly even 3 short carpet runners. i love the idea of wainscoting-but you will lose precious centimetres. You can get paintable wallpaper wainscotting.

I would just LOVE a space like this in my home, for I would agree with dohraime above and keep the flow and view into your lounge space free-flowing. One can never have too many views to gaze at! I would make the space say "library" and: - keep the wall unit and include plenty of books - keep the gorgeous floor lamp - add 2 small lightish coloured, plain or patterned comfy chairs and a small coffee table underneath the stairs - add a complimentary console table on the wall opposite the stairs - add a large stylish mirror over the console table to bounce light around the fairly dark space - add a generously sized, patterned rug with some lightish colours in it, round or oblong, whichever you prefer. If the comfy chairs are patterned, ensure the rug coordinates with them Oh .... And a statement pendant ceiling light as well even though you have down lights already good luck!

Consider combining the concept of console with shoe storage. Check out this cabinet for example. http://www.mattblatt.com.au/Credenza-Storage/Bakbo-Tall-Cabinet.aspx?p19566c17#19568 It has a mid century modern feel and comes in both blond and walnut timber. While this style of cabinet is a bit taller than the average console or buffet it is still low enough for a mirror over the top. The advantage is it's a stylish piece of furniture that has shelves for shoes, hidden behind doors. Although the entry/hall is long it is already full of doors so try not to fill it up with furniture. A single cool looking piece of furniture on either walls #1 or #3 with some fabulous artwork on wall #5 and whichever of #1 and #3 doesn't have the cabinet on.

Hi, We also break up a long hallway with zones, and often do it with the ceiling and shallow nib walls / feature recesses. You have the width to do a few things. When the hallway is straight we create short length dropped bulkheads and 'frame' areas that lead into specific locations... eg the entry can have a small dropped bulkhead at the end of it that feeds into a feature protruding wall combined with a different ceiling height. That wall might sit out by a couple of hundred mm and that allows anything from a series of recessed boxes (shelf like) to a feature frame for large artwork. We also change ceiling heights through sections to zone off eg the living end vs the bedroom end or place features such as light wells in them. Cheers
