dha secure 17 unique holiday cottages on Osea Island

Osea Island is one of those unique places – a truly tranquil and wild location, but in the South East. The island is in the Blackwater Estuary and has a history of being used as a retreat. It is private property and has an atmosphere that is much intensified by the fact it is completely cut off at each tide.


DHA have obtained planning permission for 17 new build holiday cottages in the context of countryside planning policy restrictions, high value international wildlife designations (RAMSAR and SPA), and designing within the setting of listed buildings. The island has a hamlet in the middle and is otherwise wild shore or is managed under low intensity agriculture including fields in stewardship for bird migration.  For visitors with children it is a safe car free place where children can be as free to play as they were in the 1950’s.  

When the navy pulled out after WW1 and later after WW2 it left the main house, the chapel, houses and other buildings built by philanthropist Frederick Charrington and the old Osea Farm, whichare now derelict. The proposed single storey holiday cottages are sited in this cluster of existing buildings. They are naturally energy efficient.  A modern former corn store more recently used for boat building is to be converted for fitness and an indoor pool. DHA Transport advised on the causeway access which is used at low tide. Environmental studies were provided by MLM Environmental.

Stiff and Trevillion Architects produced a very well designed proposal suited to this tranquil setting, which will be appreciated by those who value the natural environment of Osea Island. For information about the history and celebrity links of Osea, visit
