ᐅ Quotation for Architect-Designed House, 150 sqm / 750,000 Euros

Hello, I would like to get your opinion:
Project: Detached single-family house on a 600 sqm (6,458 sq ft) plot (fully serviced, perfectly flat) in a suburb of Freiburg, Bauhaus style, 150 sqm (1,615 sq ft) living space, slab-on-grade foundation - no basement, underfloor heating with an air heat pump supported by solar energy, 2 modern bathrooms each with a shower, high-quality parquet flooring / porcelain tiles, two-tone triple glazing with electric external blinds, oversized double garage with electric sectional door, etc.
Offer from an architectural firm: total price €750,000 – WITHOUT land and WITHOUT exterior landscaping
…I am a bit shocked…

Me too! Are other architectural services included in the 750k?

...Architectural services levels 3 to 4 fully included!

What kind of materials are being used for around 5000€ per square meter (approximately $540 per square foot)? Even including the architect’s fee.

Wow! 🙂

This should actually be quite doable for half the cost. Is everything made of gold there?

...good, high-end fittings, without ventilation or air extraction, no technical gimmicks, a "luxury version" would cost around 850,000
