GILROY College students will provide hours of fun for the pupils of St Gabriel's School for Hearing-Impaired Children.
Thirteen students built a cubby house during their construction classes this year to donate to the primary school.
Gilroy College's leader of learning, Stephen Bushell, said students learned the same skills and techniques they would have if they had built a house frame.
"We just did it all on a smaller scale," he said.
"It has the framework, a gabled roof, it's clad with marine plywood and we painted it green and gold for the Aussie cricket season."
Student Aaron Wilson, 17, said: "The kids were pretty happy — they loved it."
Ella Kelly, 6, is among 70 pupils who will enjoy the gift next year.
"It's so much fun," she said.
"I like it a lot.
"We can play shops or peek-a-boo".
The head of campus at St Gabriel's School, Dianne Hooke, said the school was thrilled to accept the donation.
"A cubby provides the most delightful opportunity for pretend play and for students to practise organising their ideas," she said.
