Children with sensory processing needs will now be able to engage with imperative therapy sessions at Woodlands Meed Primary School at Burgess Hill.
The special needs institution has been unable to provide sensory therapy to many young people who would benefit from them.
But thanks to a grant of £17,443 from the William de Warenne Lodge the two rooms have now been transformed offering a top-of-the-range sensory space.
Anna Hull, who supports with fundraising at the school, was ecstatic at the launch of the rooms on Monday November 6.
She said: “It is fantastic to see so many children benefiting from the room and some of those we have not been able to take care of can now be supported.
“It was a really happy occasion everyone was so grateful to the William de Warenne Lodge.”
The mayor of Burgess Hill Councillor Jacqui Landriani cut the ribbon officially opening the area.
Both rooms will offer a space to relax and calm down, as well as more practical activities including a sensory swing, climbing wall and atmospheric lighting.
Paul Gosling, from the Lodge, said: “Thanks to Chris Hunt for discovering this project. It has been humbling.”
