The shrub you have is a winter flowering jasmine - jasmiine nudiflorum.It will respond well to being cut hard back now if you want to keep some of it.
You could plant a climbing Hydrangea - Hydrangea petiolaris
which like the jasmine can be cut back to keep it close to the wall and shaped around the windows. Bright green foliage followed by white panicles of flowers in May , yellow foliage in autumn and a tapestry of rich brown branches in winter. Takes some time before it clings to the wall my itself but grows quite quickly.
