An enchanting private island with a variety of properties, event venues, beaches, land and beautiful nature on London’s doorstep.
Our collection of properties range from grand houses to cosy cottages and apartments and our event venues are historic and quirky.
Osea is an eclectic, rustic and extraordinary experience and a blank canvas for creating memories that will live on for years to come.

October 2024We recently hosted a learning retreat on Osea island and could not have asked for a better experience. The island is beautiful and unusual. The team on the island make our stay amazing and ensured everything ran smoothly.
