Offer for heating / sanitary / ventilation - is it realistic?

I did that myself, so the planning was done by Lüftungs.net. There I bought the shell components and laid them on the precast concrete ceilings according to the instructions.

Well, but the OP had a complete offer made without any personal contribution...

I also can't compare a self-built Ytong kit house in price with a turnkey one from the main contractor...

I understand that too. I only wrote what we paid for the trade. 10k€ sounds plausible, but with some craftsmanship skills, it can be done cheaper. I'll probably end up at around 6k€ in the end.

How do you manage to configure for €7500 at Reuters? Whirlpool tub or something like that included?

No, nothing special from my point of view. At most the Geberit DuoFresh maybe, but they will probably be removed, then the controlled residential ventilation has to handle the odor. Otherwise, I don’t find anything extraordinary there.

Hello everyone,

we have just received the offer for heating/ventilation/plumbing from the first craftsman contacted by our architect and are rather “not so pleased” about the prices :-(. What do you think, are the prices overpriced or okay?

Total gross price 59,300

The offer includes the following individual items (net prices):

[*]Air-water heat pump Viessmann Vitocal with connection package 14,770

Total net: 49,830

Sanitary fixtures are not included. You could get them yourself and have them installed for 1,800 net.

I would appreciate your opinion. Thanks!

Is okay, even rather on the affordable side. And the option with [Sanitär] will save you a lot of money, you usually don't get that!

Would definitely go for it, good offer overall

That's fine. It could be 2-3k€ cheaper in total, but the architect will get that for you in the price negotiation, 5% always work, possibly with a discount. And you have the huge advantage that you are allowed to obtain the objects yourself, that is a gift that should actually be factored in.
