I'd suggest a shallow bench underneath the window and flank the windows with a base cabinet on one side and a desk on the other. Then open book shelves above the base cabinet and desk. I can't tell what the dark wall is on the one end. The steps need to curve from the door to the wall. A smallish sofa would be great for viewing a flat screne TV and a square table and 3 chairs up against the dark wall would be a great place for puzzles and games. Put a pendant over the table.

Being able to build your own house is a wonderful opportunity, and when you should be able to customize it best to your own personal needs. So you'd need to be more specific about your family & lifestyle .. how many bedrooms & bathrooms do you want/need? How old are each of the family members? Will the house be detached, semi-attached or attached .. which controls window placement? Do you have a casual or formal lifestyle, want individual rooms, or open concept? Does family do a lot of cooking, and have activity revolve around the kitchen? Does that "triplex" include a basement and/or garage? Bottom line, is that "the best ever designed plan" might be totally different for you, than me, so a designer needs more details from you!

HI RinaI do agree I love jewelbox rooms, but I consider them more cosy ... and with a grey marble floor it goes all Versace Italianate! I am trying to balance the colours by bringing in a pattern on the covers rather than plain. I feel this will bring colour without overpowering the room. In the pictures I showed above, the rooms are basically neutral but the colour is brought in via pattern - I think this might be the way to go...Ideally a green or blue on a subdued grey would be the best, but I dont know what the market is like for Sumit...Cushions can do a lot to tie in the other white/grey elements.Shelley - navy is a good suggestion, but as Sumits area is quite tall and thin, trying to keep the general area light Any more suggestions most welcome. These are just ideas after all and Sumit will choose what works for the room in the end ;-)

Draw a measured outline of your space and note any window locations and where your electrical and plumbing are currently located. Then take this plan to a company that sells cabinetry. They will have a computer program that uses the standard cabinet sizes and will be able to draw you up a plan and price it out for you.
