How expensive was your conscription / hidden costs?

The electricity bill for drying the screed was a real shock. Wow, that was a really big amount. You should clarify that beforehand - but you can't change it afterwards.

In our construction area, some already have photovoltaic panels on their roofs and apparently use the photovoltaic electricity for drying the screed? I haven’t spoken to anyone about it because we haven’t started yet... But I would find that very clever if that’s the case - especially if it already yields a good amount in the summer... Of course, you have to have created the necessary conditions for that.

But of course, you have to have created the prerequisites for that.

First, the photovoltaic system must generate enough power for it (and the screed heating consumes a lot), and second, the heating runs 24/7, so at most, you only get a fraction of that.

That the photovoltaic system including the inverter is installed already during the shell construction phase, I can somehow only imagine to a very limited extent. Having panels on the roof doesn’t automatically mean that everything is wired inside. At least for me, that wouldn’t have been technically possible at all.

Without having tried it: Can't you find the cheapest tariff on Verivox etc. and then register the construction electricity meter with the respective provider?
That way you would at least get away from the usually expensive basic supply tariff...

Of course you can. Construction site power is exactly the same kind of supply point as in a house.

The rate was not the problem - the quantity was.

Even with an architect and a basically well-thought-out cost/budget plan (ready to move in) with a buffer, quite a few additional costs have come up and are still coming up for us. I have listed the biggest items and want to distinguish between

1. caused/upgraded by us:

[*]Raffstore on the south and west side instead of blinds (approx. €2,000)
[*]more expensive floor coverings (approx. €3,000, beware: this adds up quickly!)
[*]more expensive bathroom fittings and equipment (approx. €1,500)
[*]hidden hinges on interior doors (approx. €1,000)
[*]use of dehumidifiers and fans (approx. €1,800 rental plus electricity only)
[*]forgot shower doors (approx. €3,000)

2. botched by the architect due to not being considered/forgotten or due to insufficient acceptance:

[*]central controlled residential ventilation not considered (approx. €400 recalculation by structural engineer)
[*]corrections due to insufficient acceptance/site supervision (approx. €2,000)
[*]plastering and painting work of the garage not considered (approx. €2,500)
[*]attics not considered (approx. €5,000)
[*]interior (hardware store) and exterior window sills not considered (approx. €3,000)

I don't even want to start with the outdoor facilities. Despite prior agreement about the work, we are currently at three times the budgeted costs here. Apparently, no concrete offers were obtained beforehand. Now we have to tackle the work little by little, whenever we have liquidity.

Therefore, I can only urgently recommend to everyone, whether with a general contractor or an architect, to check all offers themselves and to ask the offering trade directly in case of any uncertainty.

By the way, we have meanwhile terminated the contract with the architect.
