We've got two bay windows (one at the front and one at the back of the house). Each face has two panels, and they're approximately 1.8m in height total. Photo is of the front of the house, where we have half height cafe style shutters. Back of the house windows are currently bare.

We want to add blinds at the top to avoid morning and evening glare, but because we usually want as much light as possible (when it's not direct in your eyes!) we want to ensure we can open the blinds as much as possible - and expect to have them fully open almost all the time. The front ones would only need to cover the top panes, about 1m drop. The back window blinds would need to be at least 1.5m drop, and ideally the full 1.8m.

Roman blinds and roller blinds both fit the bill, but we don't like the idea of having three chains hanging down. The middle one in particular wouldn't really have anywhere to attach (for child safety).

So we're thinking that pull-down roller binds would be the way to go. As long as the mechanism isn't too bulky, they should be the least obtrusive option when open. But! We've struggled to find them. Nowhere online seems to offer good photos or dimensions of the mechanism (which we want to be as small and as minimalist as possible). We've actually got an old Ikea pull down blind in the children's room which we're very happy with but they don't do them anymore. The closest is the Liselott but although the mechanism looks fine we wouldn't want the pattern, and also the sizes aren't appropriate. We'd need approx 55cm and 100cm widths.

Does anyone have any recommendations? Many thanks!
