Custom bedroom wardrobe or standard furniture?

if you look at the providers, you can quickly see what it costs - and then you have to assemble all that crap yourself. Otherwise, it quickly gets really expensive. Our living room furniture would have been significantly more expensive online - but maybe that was because of the different depths, etc. Just plan what you like with such a provider, complete with interior fittings of course, and then go to the carpenter and have him make an offer.

So it really only works well with a carpenter. In particular, they can shine with on-site consultation. There are really individual solutions, but also approaches.

The other alternative was also mentioned. Ikea Pax elements; then adapt the whole thing with drywall/shelf accordingly.

Who will get to enjoy the "design" there for several thousand euros? Pax in (or something else off the shelf) and do the rest with drywall, then it will be flush. Or intentionally leave the gaps, a ironing board fits well behind there. No one will see it anyway. You can get Pax to fit in 275cm, right? Pretty annoying to have forgotten 9cm of space in the planning.

Based on our experience with carpenters, I would estimate the cost at around 5000-6000€, which is quite a lot compared to a Pax and some drywall. You just have to consider whether it's worth the money to you.

@TE: your 2.91 means, however, that the sliding door is already in the passageway in front of the dressing room.

The left wall is even a bit shorter.

The sliding door will probably not come.

It is best to give it to a carpenter who consults on site, takes measurements, and then manufactures individually.
