Duplex offer assessment?

Good evening everyone,

I came across the following offer on the internet and wanted to hear from people who know a bit about it what they think.

This semi-detached house is supposed to cost 130,000 euros.

My question is what other costs I would expect such as connection fees, etc.?

---------------------------------------------------

Living area: 113.00 m²
Plot: 500.00 m²
Usable area: 15.00 m²
Location: Bremen

Property description:
In the "Am Bodden Süd" development area, 8 high-quality semi-detached houses are being built on beautiful south-facing plots.
This development area is ideal for young families, as it is located at the end of a dead-end street and the little ones can play relaxed with their Bobby cars on the street.
There is also variety for playing on the newly designed playground 100 m away.

So far, we have built 2 semi-detached houses in this area, which are already occupied.
These two semi-detached houses are being built on the south-facing plots No. 5 and 6 of the site plan.

With us, you do not buy a standard house, but your unique house.
You acquire the plot directly from the owner and conclude a builder contract with us for your individual semi-detached house.
We hope you like our company philosophy and look forward to your inquiry.

Location:
The "Am Bodden Süd" development area is located between Schwanewede and Bremen.
The distance to the center of Vegesack is about seven kilometers, the distance to the center of Schwanewede is about three kilometers. In Vegesack and Schwanewede, as well as in the surrounding area, there are numerous shopping facilities for short- and long-term needs. The highway access point Frage an the A 270 towards Ihlpohl (access point A 27 towards Bremen, Bremerhaven and Hamburg) can be reached by car in less than five minutes. The direct highway access Schwanewede to the A 27 is about seven kilometers away. Kindergartens, schools, leisure and sports facilities are also numerous in the nearer and farther surroundings. A nature reserve and a newly created playground are directly adjacent to the development area.

Equipment:
All houses are standardly and without extra charge equipped with high quality:

- Branded gas condensing boiler
- traditional solid construction "stone by stone"
- colored plaster of your choice
- underfloor heating in the bathroom
- generous plastic roof overhangs
- tile selection up to €30 / m²

Further advantages:

- including handling of all official procedures
- coordination and submission of building applications
- construction time: 6 months
- regional construction companies from our region
- implementation with own craftsman team
- mediation of necessary insurances
- mediation of financing offers

The price and then high-quality equipment, plus a relatively large plot. Either the location is poor or..?

So from my point of view, the price is only for the house. The land is extra..

In terms of the equipment, I can't see anything high-quality.. a simple gas boiler.. only underfloor heating in the bathroom.. which tiles up to 30,--? What amount for the rest of the floors? Which windows, which insulation? Plastic roof overhangs are also cheap, which color plaster? What equipment do the bathrooms have, is there anything left to do inside.. which electrical system, how many switches and sockets, network, etc.. all missing information and that's with 1 minute of thinking
