FAB window. How about a hinged rod, or a room width rail. The 1st will open and sit against a wall, to be closed when needed, or one at each side. The curtains would be floor to ceiling and look gorgeous whether open or shut. A room width rail at ceiling height could sit the curtain to the left of the window when open, perhaps with a luxurious tie back and the curtain, when pulled over, would cover the entire wall as before. I DARE you to go for WHITE linen or, better still, WHITE velvet. Stunning! Bee

Wow! What an amazing space and fantastic opportunity to shape your new home. Which floor is it on in terms of needing privacy? I imagine there will be a requirement to do work to the ceiling to comply with fire regulations? If that is the case the windows will be recessed into the ceiling which may limit your options. Clearly with single glazed windows and no insulation to speak of on walls and possibly floors it would be ideal to save as much heat as possible escaping through the windows. I highly recommend Luxaflex ‘Architella’ pleated blinds. They make a huge difference. If privacy is an issue you could have day and night versions in one headrail. Good luck with this incredible project.

As you say shutters would be the most expensive so you are down to either blinds or curtains or both. If you are more contemporary with your choices then I would opt for blinds but if you feel as though you want something more fancy with texture then curtains fits the bill. I originally had curtains at my bay window but they were a pain to keep dragging around the corners of the pole so also invested in blinds which have been a godsend. We only use the blinds now at night but the curtains offer a 'frame' on the window as the lounge is on the front of the house so at least it looks as though we have something at the windows for passers by as you cannot see the blinds when they are up.

I’ve recently bought a large Roman blind from Blinds2go and it’s fab. The price was very reasonable, the service quick and the quality good. You can also order free fabric samples.
