There's no fear of a new Antarctic base slipping into the sea - it's being built on skis so it can be moved away from any danger zones.
The base, for the British Antarctic Survey, will be built on an ice shelf by London company Faber Maunsell and Hugh Broughton Architects.
Previous bases have not been able to withstand the harsh conditions.
The current one has been there since 1956 and is in danger of drifting into the ocean if not replaced soon.
The current base
The building materials for the new base will be shipped out from the UK and assembly work will start in about 18 months' time, during the Antarctic "summer".
Important scientific work is carried out at the base.
The new building should provide a comfortable place where the staff can live and work while temperatures outside plummet to -40C.
