Our Profile

Legal Advice

Our main focus is on providing extrajudicial advice in the drawing up and drafting of contracts and other legal relationships.


We specialise in the following areas: private construction law, plant construction law, areas of law covering architects and engineers, developer law, residential property law, commercial tenancy law, real estate law, and real estate transaction law.


Our law firm advises and represents investors, property developers, building contractors, architects and engineers who are nationally and internationally active. While the majority of these are proprietor-run companies we do of course also represent builder owners.

Judicial Representation

If a legal dispute cannot be avoided, we are on hand to provide decisive and competent legal representation both in court and in arbitration proceedings, bringing twenty years of legal process experience to the table.


Mediation is a valuable, interest-oriented alternative to classic dispute settlement procedures.


Mediation processes can help to sustainably resolve a dispute in a way that saves both time and money. We’ll verify if your particular problem lends itself to mediation as a solution. If this is the approach decided on, then we’ll be ready to structure and moderate that mediation – whether we act as mediator or as your representative in the process.

The corporate philosophy of our law firm

Professional expertise and mutual trust

We put great value on building personal, long-term client relationships. The reason why our clients stay with us over time is that we combine our considerable professional expertise with a business relationship based on mutual trust and reliability.

Solution-oriented approach

The focus of our work depends equally on thorough expert analysis of the legal issue at hand, and finding solutions that are adapted specifically to your business and/or personal goals. We’ll deal with your legal issues with the greatest of care, regardless of their financial worth.

Building law and real estate law
