Hi Chris, Wow, your place sounds fab, I'm v. jealous! There are a couple of different ways to dress a corner window in a modern home - I'd think about a panel track system of sliding floor to ceiling blinds for a clean lined look, try Panel Track by Levelor or the affordable panel curtains from Ikea. Another option would be to think about vinyl mesh roller blinds, mounted above the window and long enough to run to the floor; again Levelor is a great option.

If you'd like to go with custom drapery there are ceiling tracks that can run around a corner. Often called 'hospital' tracks, most custom drapery firms (like Drapes & Sew Much More in Toronto) should have access to them; though I would keep the fullness down to a minimum to keep the drapes from looking too trad (no pinch pleats and maybe 1 1/2 times the length of the track, rather than the standard 2 1/2 times), and definitely run the drapes floor-to-ceiling.

For placing your bed against the window, either keep the headboard at or below the sill height (think about a upholstered headboard), an inch or two in front of your drapes. Or why not consider having a narrow false wall built to the ceiling and placed a few inches in front of the window treatment, to set the bed against - that could look ultra modern!

Cheers, Arren
