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.

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.

overlapping comments and questions!!..i would have less glass in the room but more carefully positioned but have the walls already been built? and you said the joiner wanted 1500mm on either side of the heater and with the heater, say 900mm+ 1500 + 1500 =3900mm leaving only 700mm for the window seat along that end wall so don't think the corner position works any better but, assuming that the window seat is essential for seating crowds, i suggest that the western window could be shorter with bookshelves on sides and above the window leaving north and south walls for the couch and heater (although the heater and couch in my first suggestion could also be swopped over) but it's difficult to be precise without accurate window sizes and the orientation and direction of best views ....to have pendants for dining tables would make it impossible to rearrange furniture so i would have ceiling spotlights evenly distributed around the room with pendants only over the island...and i'm wondering about the room outside the living areas (an entry foyer perhaps??) and other options for the heater and piano but we need names and measurements of all the other rooms to make any other suggestions and/or could you use a heating cooker positioned in the kitchen?
