Designed by Bradford-based architect Rance Booth & Smith, the project is part of a wider regeneration and restoration of the 36ha West Yorkshire park.
The practice's single-storey Interpretation Centre, which was submitted for planning in August, will feature a curved dry-stone wall and a glazed public area for events and exhibitions.
Councillor John Ford, the leader of Calderdale Council, which is also funding the parkland revamp, said: 'The council is delighted that the heritage of Calderdale is being preserved and made more accessible for future generations.
'This grant means that we can conserve the park and its structures and provide the public with the opportunity to learn about Shibden's history.'
Other proposed work in the park includes the remodelling of the medieval Shibden Hall and museum, the refurbishment of the rangers' barn and the reconstruction of the boathouse.
