Interesting house construction offer? Experiences?

You only build once and should fulfill your wishes as far as possible. From experience, I can only say that it always gets more expensive. You can go through with it like this, but you need buffers or the possibility to build one up.

It is often the little things that add up over time.

For example, with electrical work, often only a minimal number of sockets are included and the rest costs extra. Sat included?

6 LAN sockets are just a minimal number. Please make sure they are at least double sockets. Also make sure that on every floor there is a socket somewhere central in the house for a WLAN access point.

I don’t have a single Landose and also live and can watch TV, I’m on the internet with 50 thousand speed and have a telephone. Sometimes theses are put forward here and dogmas propagated that simply are not true. Dogma one, a modern house must have a controlled residential ventilation system. Wrong, it must have a ventilation concept. Dogma two, it needs Landosen. Wrong, it only needs a fast DSL connection and a well thought-out WLAN. Dogma three, kfw 55 or better is a must. Wrong. The extra cost of these insulation levels is disproportionate to the slight energy savings compared to the Energy Saving Ordinance standard. Dogma four, we do the garden ourselves. Wrong, the landscaping of an area whose origin is a construction desert is overwhelming for most. Dogma five, it needs a garage. Wrong, it needs a storage space for this and that, but cars were designed and built to be outside. There are certainly other so-called dogmas that are not true when you examine them or are simply just fashion. Karsten

Is the offer now from Town & Country?

Additional costs seem to be reasonably calculated.

What does the electrical installation look like? Number of sockets, switches for lights, etc.
I miss floor coverings and painting work - quality of the interior plaster? Are the ceilings skimmed, wallpapered?
Construction site setup etc. pp. all included?

Keep furniture, moving costs, lamps for indoors and outdoors in mind.

6 Landosen are, in my opinion, reasonably placed - okay.
25 € per tile is not a bad price per se - the selection might just be smaller and maybe it won’t be 90x20 wood-look rectified tiles.

Notdlys regarding the LAN, I have to disagree with you. In 2018, LAN sockets belong in a new building. I didn't say it has to be a socket orgy, but it should be about 6 sockets. 2x for WLAN access point, TV, children's room, bedroom. And if you do it, then you do a double socket right away. That's nothing exaggerated, but in my view, the minimum standard nowadays.

Hello everyone,
thank you for your answers.
It is a Town & Country house, Lichthaus 152, without a basement.
It is a house according to the Energy Saving Ordinance 2016, so not a KfW55.

The standard heating is a Vaillant auroCOMPACT with auroTherm VFK 145 collectors. However, I have not dealt with this yet because of other concerns.

What does the electrical equipment look like? Number of sockets, switches for lights etc.

There is a detailed list of all sockets, outlets etc. per room.
Example: Living room: two single sockets, four double sockets, two ceiling outlets with series switches
Bedroom, child’s room, guest room, office each: two single sockets, two double sockets, one ceiling outlet with switch
Bathroom: three single sockets, two ceiling outlets with switches, one wall outlet
.. etc. In total:
24 single sockets, 16 double sockets, 14 ceiling outlets, 11 switches, 4 wall outlets, telephone socket, doorbell, smoke detector

If something is missing, I would simply do it myself. We have not planned this in detail yet, as feasibility is the priority for now.

I miss floor coverings and painting work

The bathrooms are tiled up to 1.20 m high, wet areas up to 2 m (here I assume patterned tiling). The floors in the bathrooms will also be tiled (25€/m²). Tile size up to 30x60 cm
For the other floors, walls and ceilings, we will do the work ourselves, although there is still the tiling package (see above).

Quality of the interior plaster?

The interior plaster is supposed to have a thickness of 2 cm, quality Q2 (whatever that means…?)

Site setup etc. everything included?

Well, the site setup etc. is included, but whether that is everything is exactly the question
