Dr. Ralf Averhaus

Since early 2008, Dr. Ralf Averhaus has been a certified specialist lawyer for construction and architectural law. His professional focus lies on drafting contracts (construction and planning agreements), providing construction-related legal advice, and handling construction litigation. Beyond his legal practice, he is a co-author of a commentary on the HOAI (currently in its 5th edition) and has written a book on fee claims by architects and engineers. Dr. Ralf Averhaus publishes in professional journals and frequently serves as a speaker, for example, in the training of experts on architects' fees in Baden-Württemberg. He is part of the management team of the Berlin Fire Protection Forum, which will take place for the 14th time in autumn 2025. In 2024, Dr. Ralf Averhaus contributed to the expert report commissioned by the BMWK on revising the fee calculation in the HOAI.

Since 2020, Handelsblatt has regularly named him - most recently in June 2025 - as one of Germany's most recommended lawyers in the fields of "Construction Law" and "Real Estate Law."

Dr. Ralf Averhaus is a member of the Berlin Bar Association.
