As far as I can see, they want to move the garage into the basement --> underground parking garage

Now it's day, sorry! So, the house is supposed to have an L-shape. However, the basement should be a rectangle. I tried to sketch it in Paint, black for the house, blue for the basement. Unfortunately, we only came up with this last week, so there are no plans yet. We will get them in a week.

Attached below the houses are a granny flat and heating room. "Next to the building," as you nicely said, space for the cars. Above that, we would like a terrace and maybe a part of lawn planting...

It is our first house and for me as a construction layman, it is incredibly difficult to realistically estimate something like this. I already know that it is basically not possible to make accurate estimates at this level of detail. I also have no problem if we are off by a few tens of thousands of euros... I just want to avoid going to the architect with my ideas, him drawing and drawing, days and weeks passing, we think about it daily, and with a detailed calculation we are then told that everything considered is financially miles out of reach for us and we are back at the beginning... I also understand that an architect does not want to carry out 10 cost calculations and therefore first creates plans and then calculates.

That is why the question whether there are somehow more detailed cost rates with which I can work myself and calculate whether it is realistic or not.

Example:
Living area high standard: 380€/m³
Granny flat medium standard: 350€/m³
Basement area (heating room and workshop): 350€/m³
"Underground garage": 280€/m³

maybe also a normal garage for comparison: 100€/m³

Hello,


Now I've finally got it, thanks!


Attached you will find a roughly comparable plan for NRW as an example; however, it is a bungalow with a ground-level granny flat + partial basement, with a usable basement of 100 sqm. This "little house" costs as KfW 40+, double garage brick-clad 6.00 x 9.00 m and with all the trimmings – ready to hand over the keys and move in, EUR 645,000.

For what you have in mind, we're not talking about just some EUR 10,000 more or less. If it is implemented as shown in the sketch, you should reckon with a really fat "8" _in front_.

Rhine greetings

Are the stated 297 sqm of ground floor and upper floor areas living spaces or gross floor areas?
