Addendum sliding door 11.5 cm masonry

Hello everyone,

we have just bought a new-build apartment, and since the non-load-bearing walls have not yet been built, we decided to make a small change.

I would be grateful if you could briefly assess this additional offer,
originally a normal passage was planned and at this point we want to provide a sliding door that disappears into the masonry.

Here are the additional costs from the main contractor:

1. Delivery and installation of concrete lintel (11.5x11.5x250cm) + masonry work: €338
2. Sliding door unit for an opening of 90cm: €910
3. Embedding the sliding door unit, double plasterboard on both sides + plastering work: €498
4. Sliding door: €395

Prices are without VAT. I find especially the price for the lintel and the plasterboard very high..
Is it generally possible to negotiate such offers or do you think the price is justified?

Many thanks

Yes, €200 less would probably be nice. But you can't do anything about it anyway, except give it up or produce it yourself afterwards.

Price looks OK. The price for the drywall panel is incl. labor. Good work should also be fairly compensated.

Drywall construction is now precisely the most cost-effective trade in terms of material + labor relative to the finished area.

The question that arises for me: previously, the passage was apparently planned as a ceiling-level lintel / load-bearing concrete ceiling? Why do they now want to insert a lintel? They should only build up the opening at the top and on both sides with drywall. A stable stud frame is more than sufficient for the installation of the (not room-height) sliding door.
