ᐅ Terraced House on a 240 sqm Plot – Fundamental Questions / Feasibility?

I have been following the forum for a while now, but this is my first post. After several years of searching in the Stuttgart metropolitan area, we suddenly have the opportunity to buy a relatively small plot of land on the edge of a new residential development.
Plot: 12m x 20m = 240sqm (2583 sqft); floor area ratio 0.4; max ridge height 9.5m (31 feet); max eaves height 6.0m (20 feet); roof pitch 35°-40°; 160,000 EUR
The plot can be built with a terraced house; to illustrate, I have attached the site plan.
To be able to roughly estimate the project overall, we have a few basic questions. Thank you very much in advance, your help would mean a lot to us!
1. Our budget is 560k. Is that realistic for a 135sqm house? Very roughly calculated: 170k for the plot, 50k for the basement, 300k for a solid masonry house from a builder (2,200 EUR per sqm x 135 sqm), 40k additional building costs. Is this estimate rather generous or tight? (We do have a buffer available.)
2. Does it make a big price difference whether we build 1.5 or 2.5 storeys?
3. Regarding the floor area ratio, is a 9x10m house plus a garage/parking space of 30sqm feasible? From what I understand, ancillary buildings may exceed the floor area ratio by 50%. 90sqm house < 0.4 x 240 + 30sqm < 0.5 x 0.4 x 240
Is there anything fundamental regarding costs for terraced houses that we might have overlooked?
Thank you very much in advance!

That means the concrete wall probably provides better sound insulation than if 36cm (14 inches) Ytong blocks were used. I think so, since the concrete wall involves a lot of "mass," which means good sound insulation.

What fire resistance rating (30, 60, 90, 120 minutes...) does your fire protection wall in the townhouse have? We built in Baden-Württemberg, so according to the General Implementation Ordinance of the Ministry of Economic Affairs related to the State Building Code (LBOAVO) -> §7:
"
(1) Fire walls are required
1.
as building separation walls when these walls are built at or with a distance of less than 2.50 meters (8 feet 2 inches) from the neighboring boundary or with a distance of less than 5 meters (16 feet 5 inches) to existing or legally permissible buildings on the same property, unless a distance of at least 5 meters (16 feet 5 inches) to existing or legally permissible future buildings according to building regulations is guaranteed,
"
Which fire resistance rating to choose here -> no idea 🙄 The construction contract and building application only mention "fire protection wall."
Hi everyone,
I’ve attached our plan including the execution details. In the end, there are no major special features here except for the following:
- Our 30cm (12 inches) YTONG wall was built in the usual way, and the visible part was plastered.
- Between the adjacent garage and our house, 2–4cm (1–1.5 inches) separation joints made of soft fiberboard were used.
- According to regulations, no windows are allowed, so the wall is considered a fire-rated wall.
-- Others in the street have installed windows here as well, using fire-rated windows, though I don’t know the protection class.
Regarding noise levels, I can say I don’t notice anything.
