What is the most expensive house in Knokke-Heist?

In March 2025, the purchase of a luxury villa in Het Zoute, Knokke-Heist by entrepreneur Marc Coucke made national headlines. This deal is now regarded as the most expensive villa ever sold in Belgium, once again confirming Knokke’s reputation as the leading destination for exclusive real estate at the Belgian coast.

The record-breaking sale sparked widespread media attention and put the spotlight back on the luxury property market in Het Zoute. Meanwhile, strong rumors suggest that an apartment in the prestigious Finis Terrae complex also recently changed hands in a private transaction for a comparable amount – another milestone in the world of ultra-luxury real estate in Knokke.

As the leading real estate agency in Knokke-Heist, we can confirm that transactions above €20 million remain rare, but are by no means non-existent. On the very best locations in Het Zoute, land value alone often exceeds €5,000 per m². When this is combined with large plots, exceptional locations, or villas of historical and architectural significance, prices of €30 million and beyond are both realistic and already achieved.

Iconic properties such as the Manoir du Dragon, the legendary villa Fort Sint-Pol, or the exceptional residence Le Vieux Moulin represent the absolute top of the Belgian real estate market. These exclusive villas in Knokke – if they were to be put on the market today – could also be valued at €30 million or more.

Knokke-Heist thus confirms its position as the most exclusive real estate market in Belgium. Anyone searching for a villa for sale in Het Zoute or a luxury apartment with sea view in Knokke is entering a market where discretion, prestige, and quality set the standard.
