Hello again,
first of all, thank you very, very much for the numerous replies. You really helped us with that, and meanwhile we are trying to approach the whole thing a bit more structured.
The following has happened:
We have meanwhile spoken with the municipality.
The land price is absolutely non-negotiable. However, the municipality has committed (in writing after the purchase commitment of the land, but BEFORE signing) to cover the costs for the removal and disposal of the grass and shrub growth (which is probably about 2 meters high) and for the retaining wall.
In the meantime, we have also spoken with two architects.
The first architect is building three plots next door (yesterday the excavator arrived and started with the excavation). The couple is building with similar ideas (he showed us the floor plan on site and explained it), so with 170m², a basement and driveway to the 2m elevated garage in split-level construction. All in all, i.e. move-in ready including land, incidental building costs, photovoltaics and architect’s fee, the couple comes to just under €600,000. Their plot, however, is 150m² smaller (so for us +€30,000). The building ground itself is soil class 6 and excellently load-bearing. According to his own statement, he does not need a building ground report, it would be wasted money. Except for this confusing point, a really very, very likeable person.
The second architect was recommended to us by the municipality itself. He planned a multi-family house on the first and second plot next door, which in a way could have been built at any time. However, the investor found no buyers, so had to discontinue the project and is currently trying to resell the plots.
That means this architect (both are actually retired for some time) knows the conditions on site very well. In a first phone call, the architect spoke this morning of a very difficult slope to build on (soil class 6 - he had a building ground report prepared for the two plots). It is difficult to assess where one will hit solid rock during the excavation (then chiseling would be necessary), so he expects additional costs for the excavation here that cannot be calculated in advance. Otherwise, we would have to agree (especially with regard to age) on the many stairs (just under 40 to the ground floor).
We have arranged a first meeting with this architect for next Friday.
We both have meanwhile created a floor plan, which we initially discarded again and again. Now we are at the point where we would like to present it to the architect.
We have discarded the driveway to the garage; instead, we would like to build the basement on the garage, then the ground floor stepped back to the rear and again stepped back the upper floor on top of it. Many stairs, yes, but later a small goods elevator (60x60x100) from the garage upwards, initially only the empty shaft (cost about €10,000).
Unfortunately, I don’t have a scanner here on site but will submit the floor plans the day after tomorrow.
Next Friday we have appointments with VR Bank, Sparda and Sparkasse. We now reckon with 2.5% effective annual interest at 2% repayment and 20 years term for €625,000. Added to this are almost €35,000 equity. There have been no talks with L-Bank or KFW yet.
Somehow we are currently oscillating somewhere between "We’ll try it!" and "Come on... let’s wait a bit longer before building!"
I think on Friday we’ll be a good deal wiser again...
Thank you very much for reading!
