RIEDEL THAN: Merger in the new-build sector
Two strong brands. One shared goal.
RIEDEL’s New-Build Sales division and the property development consultancy Dr. THAN Immobilien are combining their expertise within the newly established RIEDEL THAN GmbH. The aim is to create clear added value for property developers and buyers by offering an unrivalled range of services in the design and marketing of high-quality new-build projects.
“The partnership between RIEDEL THAN creates a new strength in the design and marketing of new-build projects. Ron Than’s consultancy expertise and his flair for marketable concepts are of great value to property developers – through our reach and market presence, we provide the decisive edge for even greater success.”
Markus Riedel, Managing Partner, RIEDEL Immobilien GmbH
Design expertise meets marketing excellence
As a consultant to discerning property developers, Dr THAN Immobilien has set new standards with the marketing of projects such as The Seven, the Lenbach Gardens and, most recently, the Mandarin Oriental Residences in the Falckenberg Ensemble.
RIEDEL THAN brings together more than 90 sales professionals with industry-leading digital reach, comprising over 11 million contacts per month, 153,000 website visits per month and currently 76,000 active client enquiries. The result: 325 properties sold in Munich in 2024, with a total value of over €600 million.

“The merger to form RIEDEL THAN offers property developers a comprehensive package that goes far beyond the consultancy and marketing services previously available. What Markus Riedel and his team achieve through their access to solvent buyers and their strength in marketing and sales is exceptional.”
Ron Than, Managing Director of RIEDEL THAN GmbH
Two family-run businesses, a clear stance
The merger of RIEDEL and THAN brings together not only expertise and strategic vision, but also shared values. Both companies have enjoyed success in the premium segment for around 40 years; they are family-run in their second generation and characterised by a strong commitment to their values.
Together, the partners embody a new approach to service. Their aim is to bring properties offering an exceptional quality of life to the market, thereby creating lasting added value for developers and buyers.

“RIEDEL THAN stands for clear principles and a culture centred on values and consistency.”
Martina Schumacher, Managing Director of RIEDEL THAN GmbH
A leadership duo with expertise and vision
Under the leadership of Ron Than and Martina Schumacher (previously Head of New Build Sales at RIEDEL), the industry’s most comprehensive range is being developed – all from a single source.
RIEDEL THAN – the comprehensive partner for property developers
RIEDEL THAN supports property developers from the initial concept right through to targeted marketing to the high-end buyer segment in Germany and internationally – thereby positioning itself as a comprehensive partner for sustained success.
