I know you said no Ikea but here's what we found for what it's worth. We trawled the second hand market and had a look at some of the draw packs that could have been adapted. There's some smart storage ideas for bedroom from companies like Sharps that could have some really good crossover use for climbing kit. The important thing for us was functionality.
In the end, after pricing up sheet material and all the faff to get the various parts, we ended up at Ikea as the alternatives couldn't beat them. Using their system we were able to maximise the small spare bedroom and get all our kit organised into open fronted carcasses. The boot drawers, steel mesh draw packs and hanging options have been fantastic.
We've had it 2 years and getting kit ready for everything from sea kayaking to all the various climbing to all the hiking and camping is now so much easier. I just wish we could have found something else as I absolutely hate Ikea. Will be interesting to see if you find something better.
