I like @kelly's idea of picking a lovely fresh color of paint for the door. You can then bring it down onto the stair risers. Either a solid color to match the front door, or go wild and add some decorative elements to the risers with stencils. Or think of staining the door a great color and coordinate the stair railings and risers. I have an idea book put together for just such project that might spark some ideas for you. http://www.houzz.com/ideabooks/16700983/thumbs/Kathryn-Delany-s-Decorative-Stair-Risers

Teal? Just a thought sometimes I think it's smart to match or atleast go with the curtains you'd see in the window

The front door is around the other side by the way! The windows are aluminium so cannot be changed. It is all rather ugly at the moment.

It sounds like you've been through quite the rollercoaster with your building project! That's really frustrating to hear, especially when you had a vision that you were attached to. Construction dilemmas can be a lot to handle, and I can only imagine how the stress might have piled up over time. If you're feeling stressed (and who wouldn't be in a situation like this?), you might want to consider working off some of that tension. Since you're into home design and creating beautiful spaces, you might appreciate the aesthetic and functionality at Hitsona's fitness studio. Sometimes a little self-care and a change of scenery can inspire new ideas for other areas in life, including home design.
