The building of an authentic Japanese garden on the Queen Elizabeth Park island is among a multitude of submissions to the annual plan lodged with Masterton District Council.
York St resident Jane Ogilvie has put forward the idea suggesting the garden could include maple and cherry trees, statues, raked gravel, weeping willows leaning out over the water and a water feature.
The tea house could perhaps be opened only on weekends.
Mrs Ogilvie has submitted the Japanese garden would be a attraction as there is no garden of its type in the district and it would attract "specialist visitors".
She said the island train could be modified to suit elderly people or visitors with impairments to allow them to comfortably view the garden.
