Alright then, since it's now 2/3 finished, I think I can give away what the top two levels will be
So, a friend of mine (also into fairly similar interests) got me into, of all things, doll collecting, specifically, 1/6 scale (Barbie sized) fashion dolls!
Their suggestion came from my interests in cosplay and fashion, and figurine collecting, and they suggested trying the Japanese 'Jenny' line since these are similar to Barbie but with a much more Japanese emphasis, and consequently are more anime-like in some regards.
Well, aside from a couple of those on the way from the East, there were a couple of mainstream fashion dolls that caught my eye here in the UK, matching my preference for goth/punk style fashion; Moonlight B.B from the LOL Surprise 'OMG' line, and Emi Vanda from the Rainbow High line.
However, there was one glaring issue; I could display these on a shelf, but that would be tricky in a room with limited shelf space, so I turned to creating a shelf unit above my stairs (as previously noted) to fit them, and other things.
In the end though, I was tempted to buy one of the various pre-made 1/6 scale dollhouses, figuring I should have a dollhouse for them of some sort, as opposed to a shelf, in order to do the hobby properly, so to speak.
Big issue was (almost unsurprisingly), most pre-made doll houses tend to lean towards pink colours (which I didn't want), and none were of the right size to fit the space I had, so I decided to do the next best thing, and make 2 levels of the proposed shelf unit into a doll apartment, hand-built and furnished by yours truly
As such, I retooled the middle and top levels of the unit to be partly taken by the rooms for this apartment, retaining space for storage too, and of course a dedicated level at the bottom, in line with my Plarail bridge, for a reversing loop to be added.
So, my project was to create a totally bespoke storage unit/doll house, and if I do say so myself, it's going rather well

As you can see, it's unfurnished at present but I have furniture and decorations on the way, and obviously the top level needs the rest of its walls added, but it's definitely taking shape. The plan is to furnish it in a contemporary, realistic style, with electric lighting and other features.
I admit I'm rather proud of the lift, as it was designed to engineer past several problems I noted with the Barbie and competition equivalents, those being a lack of motorisation potential (my lift will be motorised, connected to the lighting circuit of the apartment on a 12v supply), and in the case of several, not compatible with the Barbie wheelchair - A small detail, but as someone with very strong feelings about inclusive design, it was an absolute must that the lift be able to accommodate the wheelchair (and occupant) as easily as a standing occupant.
In addition, it uses a metal drawer runner (mounted vertically) as a guidance system, giving it a very smooth and level motion compared to the simple friction systems on commercial houses.
Tl:dr, Barbie Dreamhouse, eat your heart out, because I knew I could engineer better
For the record, this whole build, including tool costs, was still about £100 less overall than a Barbie Dreamhouse currently costs in the UK, although that is before decorating, but that's worth thinking about especially when considering how this bespoke solution is much better and fits the surroundings much better, IMHO
