Here you'll see some of the bespoke stairs i have made & fitted, usually made to get into the new loft rooms i have created. I try to match them up, fitting them over the existing stairs, obviously to save space. Sometimes i make them on site or in my workshop.
I love the joinery side of my work, maybe you will see something you like or get some ideas.
These pictures are of stairs i have made, look close at the detail too.
