With $3.5 million in the kitty, Katherine Town Council has revealed new plans to focus all its spending at the Katherine Terrace park.

There would be new toilets, shade sails, a cafe, sculptures and even a new town clock.

Plans show all the existing structures other than the trees would go.

The latest project design has little in common with the first plans unveiled by architects Ashford Consultants in May last year.

That original brief states: "The principal objectives are to master plan for and deliver the first stages of the revitalisation of the Katherine CBD so as to provide it with a beautiful, inviting and functional street presence for locals and visitors and to establish it as one of the best township CBDs in Australia."

The NT Government handed over $5 million to the council in July 2018 for the CBD upgrade, $1.5 million of that has already been diverted for the hot spring project repairs.

Those plans were heavily criticised for being unaffordable and some elements, including elaborate shade structures over the pedestrian walks, were seen as dangerous.

Council will vote in the latest plans at its monthly meeting tomorrow night.

Council documents show a revised design brief from late last year which focused heavily on Railway Terrace was dropped because of the original intent to upgrade the town's CBD.

Some of the planned parks and water features in Railway Terrace were also found to "encroach" on native title claims.

"A new project brief was compiled focusing on the town square."

Given the cost blowouts on other projects, such as the hot springs and the sportsgrounds redevelopment, council is keen to keep spending under control.

"Designers were advised that the total cost of the project must not exceed the approved budget.

"A budget will be finalised once initial design concepts have been considered," council documents state.

Ashford Group Architects, which has been paid almost $400,000 for the design work, will continue as lead designers for the new project at the town square.
