Architect Costs in Germany: A Comprehensive Guide


At Aron Studio, we understand that determining the cost of hiring an architect can be a crucial factor in your construction project. This post provides an in-depth overview of the architect costs in Germany, including how to estimate them and the role of the Fee Ordinance for Architects and Engineers (HOAI).

Estimating Architect Costs:

To estimate the cost of hiring an architect for your project, you need to consider the total construction costs (excluding the price of land). The architect’s fee is typically a percentage of this amount. For a standard single-family home, the architect’s costs average around 10% of the construction cost, with multi-family homes being slightly lower.

HOAI – A Guiding Framework:

The Fee Ordinance for Architects and Engineers (HOAI) serves as a fundamental reference for calculating architectural costs. It divides the architect’s services into nine well-defined phases, each with its associated cost percentage. These phases include:

  • Basic Investigation (2%): This phase involves taking stock, defining the scope of work, and initiating documentation while considering the best-suited contractors.
  • Pre-Planning (7%): Architects move from basic investigation to further analysis, sketching, and client-focused communication. This phase is crucial in laying the groundwork for a successful project.
  • Design Planning (15%): Architects develop sketches into detailed designs, ensuring that data is collected for precise scale drawings.
  • Approval Planning (3%): In this phase, concepts become practical, and architects deal with legal requirements and permits.
  • Execution Planning (25%): As your project progresses, this phase is where concepts become tangible through detailed construction drawings and coordination with partners.
  • Preparation of the Award (10%): Allocating areas and managing costs is the focus here. Architects compare budgets, check offers, and find the right experts for each task.
  • Participation in the Awarding Process (4%): Architects play the role of manager, coordinating and mediating throughout the awarding process, ensuring that expenses align with projections.
  • Property Monitoring (32%): This phase involves close monitoring and adjustment of project details, keeping costs in check, and addressing any minor defects promptly.
  • Property Management (2%): Even after construction, architects can assist with maintenance and problem-solving, ensuring your property’s integrity.


In summary, the cost of hiring an architect can be estimated by determining the appropriate service phases required for your project. The HOAI is a valuable tool for transparency and understanding architectural costs.
