ᐅ Single-family house construction planning for approximately 170–180 m²

Hello everyone,

I am currently planning to build a single-family house of approximately 170-180 m2 (1,830-1,940 sq ft).
Here are some preliminary details:

• Plot of about 850 m2 (9,150 sq ft) located in the triangle between Munich, Augsburg, and Ingolstadt
• Development plan requires a pitched roof with a slope of 30-45 degrees
• Required rooms: living and dining area, kitchen, bathroom, guest toilet, 2 offices, 2 children’s rooms, utility room
• Garage with two parking spaces

I have already spoken with several architects, and next week I will be meeting some prefabricated house providers.
After the first discussions, one architect told me to expect costs of around €3,500 (approximately $3,750) per m2. For 170 m2 (1,830 sq ft), that would be nearly €600,000 (about $645,000), and that doesn’t even include furnishing. I was quite surprised since I have often read on this forum about prices of €1,500 to €2,000 (approximately $1,600 to $2,150) per m2. Has the price really almost doubled in the last 3-4 years?

Since I have not yet decided between a prefabricated house provider and an architect, I wanted to ask if you think my project is feasible with a maximum budget of €450,000 (about $485,000)?

I know this depends on many factors, but I would still appreciate a rough estimate from experienced home builders.

Thank you very much in advance.
