Earlier this year the AJ Corus 40 Under 40 star walked off with first prize in the contest to design a new music and cinema building in Lerwick - to the frustration of fellow competitor Richard Murphy, who thought he had won after scoring the highest marks for quality.
Hoskins will work with local practice the Peter Johnson Partnership on the new 3,300m 2school project, which will cater for children ranging in age from three to 16 years old.
The building will replace an existing 1960s school and will provide 'cutting-edge' facilities for 20 nursery children, as well as 100 primary and secondary school pupils.
The architect saw off an impressive shortlist of names to land the Mid Yell Junior High School - including Atkins, Aedas with Mott McDonald, Gordon Murray + Alan Dunlop Architects, Edinburgh-based Nicholas Groves-Raines Architects, and Aberdeen's Mackie, Ramsay and Taylor.
Describing the winning scheme, a spokesman for Hoskins said: 'Any educational environment for children should inspire potential.
'[Our proposal] is an opportunity to create an educational environment, which balances a number of challenging aspects to create a place in which children, teachers and support staff can enjoy a stimulating and inclusive environment for learning.'
