It was 2015 when the prices were much lower than today, but I still remember the savings.
I went to one of the project bureaus and for a 3.5m x 2.35m x 0.65m built-in closet, they asked 1200e, with the fact that they would only prepare for installation, and I would assemble it myself.
I didn't want to accept that, because if I assemble it myself, I will also design it myself and give measurements for cutting...
Material came out 650e...
Is that I worked a little hard, since I brought all the material and assembled it myself, but the savings were so great that I could also build a kitchen with the rest of the money.
It's a bit busy in the kitchen now, but I'll take a picture anyway, so you can understand why it had to be custom made. It's a tiny space...
PS. I would be happy to help you, but considering that it is already getting dark in your place and you are about to open the champagne, I think you are far from Europe, the plane ticket is expensive...
That's a pretty good saving I think, and the reward of having done it yourself is solid too.
