I think curtains mounted on the wall would be pretty and give a softer effect. When you want new windows, do have a look at our 22 members - all have to make their wood windows to our exacting criteria. The frames can be expected to last around 60 years, and they won't need a lick of paint for 8-10 year.

Personally I think when houses are attached you have a responsibility to the rest of the street to have a cohesive look- it’s bad enough that people choose different window styles that fit uncomfortably with the house but then adding a change to the palate of colours devalues the road in my opinion- the other issue is that when people personalise houses it green lights neighbours to do whatever they like and it ruins the road. So I vote white windows- you might consider just replacing the glass which would be a lot cheaper than starting again. The earlier comment about the garden is spot in- this will have a bigger impact on the curb appeal.

Blinds would be the better option and would help the room feel more spacious. Wooden venetian blinds are good for controlling the light effectively, and would suit that window perfectly. You could also go for roman blinds, or if you're looking to block out as much light as possible, a blackout roller blind. You can always order blind samples to see for yourself and decide which blinds you like best. https://www.makemyblinds.co.uk/wooden-blinds/ https://www.makemyblinds.co.uk/roman-blinds/ https://www.makemyblinds.co.uk/blackout-blinds/blackout-roller-blinds/

Venetian Blinds are so flexible. You can have the slats open to let in light, or slanted down just a little to get rid of any glare. You can also open them up completely when you want lots of light. Wider slats painted white or left natural and made of wood or mdf are very popular now. Like this
