Offer Single-family house City villa

Offer and construction service description reads at a glance like any other construction service description (or offer) from a relatively inexpensive but solid provider. Our construction service description was certainly very similar. The house works, but sometimes more would be better. For example, one should think about it when a ventilation concept is missing and it is pointed out several times that the house should not be built better with a ventilation concept.

However, that is the problem: no one can just tell you in between exactly where the gaps are, which you either upgrade expensively during construction or regret in the medium term for not having paid attention to.

Since as a builder you have the option to either join the Association of Private Builders or another association or get information from consumer protection, which does cost something but is also professionally sound, I would have a professional take a look for 300 in your place. He can then also question you whether, for example, you want the 30/60 tiles laid in a pattern. There is a gap in the construction service description that says nothing about that, so it is included. The electrical system also has to be massively upgraded. These are things I see as a layman. Also, the soil report might say that you have to dig deeper than 30 cm. As a former builder, I would also reconsider Q2. It is pointed out several times that painting services are not included. I’m not going to check again now, but that also includes, for example, the roof sheathing, not just the walls. So as a layman I see a lot of potential for costly upgrades that I would ask about in advance.

When it comes to checking the technology I’m out – I’m not an expert!

Edit, (also above)... but I would want to withhold at least 20,000 for sample selections (depends on the floor plan, where the tile work ends or begins)

We definitely want to remove the bathrooms because the standard (we want large tiles) is not sufficient for us and the heating should also be redone as a result. The soil survey is already being arranged by us. In addition, we will have the contract reviewed in advance and bring in an expert from DEKRA. We have not dealt with the ventilation concept yet. Does it bring such a great added value?

We haven't dealt further with the ventilation concept yet. Does it really bring such a big added value?

This forum is full of the pros and cons of controlled residential ventilation - just sit back, scroll, and read

We definitely want to remove the bathrooms because the standard (we want large tiles) is not enough for us and therefore the heating is to be done as well.

Sanitary has nothing to do with the tiler though

In addition, we will have the contract checked in advance and get a DEKRA expert on board.

Very good!

For the painting work, I only say: watch out. This is not an amateur drama group. The drywall spackling is not easy; I don't dare to do it, and I've already managed a lot myself quite well. Also, not everyone can roll larger surfaces evenly. You must not forget the primer either. For example, my wife and I painted the roof overhangs ourselves with Consolan. That's easy. For a bungalow. For a city villa without scaffolding, hardly possible. You then have to catch the right moment when there's still one there because of the roofing. Karsten

You really have to shake your head when you see the price list.
Simply the statement that solar thermal is legally mandatory is plainly misleading or incorrect. For the 12T€, I would have a controlled residential ventilation system installed; you get much more value for the same money.
The surcharge for a heat pump is simply cheeky. However, what’s interesting is the small surcharge between an air-water heat pump and a ground-water heat pump; it is quite low considering that drilling is required for 200 sqm of living space. I would further safeguard this, for example by having the drilling depth determined by a specialist planner (no, that’s not Drill-Udo), otherwise they won’t drill deep enough and the system will be uneconomical.

But overall, affordable. Or even cheap.

The soil survey is already being arranged by us.

Go to the construction company with the soil survey and say that you want a quote based on this survey. This way, you will avoid overpriced additional charges for the groundworks.
