Eligible costs | Fee

Hello everyone,

is there a rule of thumb for the eligible costs similar to the ancillary costs (15 to 20% of the construction costs)?

I am unfortunately somewhat surprised by the fee offer from our architect.

The planned house comprises approx. 160 sqm.
The construction costs (turnkey) he calculated as follows:
160 sqm * €1,500.00 / sqm = €240,000.00 (gross)

From the €240,000 he deducted the VAT to present the eligible costs, approx. €201,000 net. So he assumes about €200,000 as "eligible costs."

Unfortunately, I do not understand this, because according to §4 of the HOAI he must apply cost groups 300 to 400.
Tiles, bathtub, etc. are included in the €200,000.
However, I cannot find these items in the cost groups.

Am I missing something?
I would be very grateful for any hints!

Best regards
Jan

Hello Allgrind,

surely you are already further ahead. I am also somewhat puzzled about the fee offer from the architect and structural engineer. The construction sum for us is also about €250,000 and the house will have a living area of about 180 m². Overall, he offers his services up to the submission of the building application for €9,900 net. How did it turn out for you?
