About Sebastian

Trusted by the world's most discerning buyers and sellers.

I began my career at Knight Frank's prime central London team before establishing my independent practice in 2007. What started as a focus on Kensington has grown into a full-spectrum advisory practice covering all prime London postcodes.

My clients include private family offices, international investors, sovereign wealth funds, and individuals seeking to make some of the most significant acquisitions of their lives. Every instruction receives my personal attention.

Three transactions over eight years. Each time Sebastian has demonstrated an understanding of our requirements that goes far beyond a conventional agent relationship.
