My specialties
Construction law
The construction and real estate sector is an anchor of stability and a driver of growth for the German economy. At the same time, it fulfills an essential function for society as a whole: it creates a liveable living and working environment. Construction and real estate law is characterized by a particularly high number of legal standards, whereby the boundary between legal and technical regulations is fluid. In addition, digital and sustainable solutions are also playing an increasingly important role here and are politically prescribed. In this complex environment, we provide you with comprehensive, targeted and specialized advice so that you are prepared for the legal challenges that arise in construction projects.
Building Smart
Building is technically complex. At the same time, it should be sustainable. The set deadline and budget targets should be met. At the moment, construction projects too often end in disputes over supplements or defects and none of the targets set are achieved. At the same time, the world is becoming more digital. A rethink is therefore necessary. Smart building is the order of the day and we provide the necessary legal tools.
Real Estate
We deal with all important issues relating to real estate and advise our clients in particular on real estate transactions, project developments and asset management. Our team is proficient in the development and management of large-scale real estate projects – from planning to execution and sales through to realization.
Planning & Project Management
Technically demanding projects require professional planning and implementation. Creating the optimum legal framework for such projects and being able to successfully accompany such projects requires a high degree of understanding of the given technical and economic contexts. We claim to understand something of what moves you in relation to your projects. That is why we are at your side in the best possible way.
Public procurement law
As specialist lawyers for public procurement law, we provide our clients with comprehensive support in all legal matters relating to tenders above and below the EU thresholds. We support the public sector and other clients in the design and implementation of procurement procedures. As lawyers for public procurement law, we also support companies that apply for public contracts as bidders and, if necessary, ensure effective legal protection – not only in review proceedings.

I fulfill this task by analyzing the problems together with our clients and discussing various approaches in order to ultimately find a solution that meets their needs.

Compliance
Companies, their executive bodies and employees have to know and observe a large number of sometimes complex rules. If violations occur, there is not only the threat of criminal and civil law consequences, but often also reputational damage and business losses. The scope of the rules, their complexity and the level of sanctions have been steadily increasing for years. At the same time, companies are losing money because they are not taking advantage of business opportunities due to excessive caution. With our many years of experience, we help you to identify and objectively assess risks without ignoring or over-dramatizing them.

I support you with the right consulting strategy to solve your legal issues sensibly without losing sight of your strategy.

Bartsch Rechtsanwälte at the EXPO Real in Munich
From October 4 to 6, the largest real estate trade fair EXPO Real took place again in Munich. Investors, project developers and construction companies from all over the world met to exchange experiences.
Our partner, the Karlsruhe TechnologyRegion, was also represented there with its own stand and we had many opportunities to talk to clients and interested parties and share our experience and knowledge.
This year in Munich, around 1,900 exhibitors from 36 countries presented their services to 40,000 participants with a focus on sustainability, digitalization and the transformation of the real estate industry.


Advoselect webinar, topic: Energy and heat
Energy security, energy supply and energy prices are not only an economic issue, but also present us with legal challenges.
The law firms in the Europe-wide Advoselect network of lawyers have therefore taken up this issue. In five short articles, you will learn interesting facts about rental and lease agreements for solar and wind power plants, about intra-European energy trading, but also about an important topic for local authorities and investors, namely the possibilities accelerated by politics to designate areas for wind power use.
Our partner Alexander Hoff spoke about this (in the video from minute 41). We look forward to receiving your suggestions.

More about me
The focus of my work is on supporting complex construction projects and Europe-wide procurement procedures. I advise (public) clients, investors, architects and engineers as well as companies on projects and, if necessary, also in court or before the public procurement tribunals. He has particular expertise in sustainable planning and construction, so-called green contracts. I also have many years of experience in awarding IT and construction contracts, particularly in the medical sector.
Professional contract drafting combined with a feel for possible developments makes exactly this possible: the risk of cost-intensive and time-consuming disputes can be significantly reduced through forward-looking advice.
Providing forward-looking advice is my strength, and I use this to my clients’ advantage. Because even in legal disputes, those who act with foresight and do not react reflexively have an advantage.
Career
I studied law at the Universities of Freiburg and Uppsala (Sweden). After my legal clerkship in Baden-Baden with stations at an international law firm in Stuttgart in the area of public law / real estate law and at the German Embassy in Copenhagen, I joined Bartsch directly in 2012. I have been a partner in the firm since 2017.
I am a specialist lawyer for construction and architectural law as well as public procurement law and have successfully completed the specialist lawyer course for administrative law.
