The "state-of-the-art all-weather viewing shelter" has provided 73 direct and indirect jobs in the construction phase, Minister for Environment and Parks Roger Jaensch said.

"Now is an ideal time for work to start so that we can continue to deliver high-quality visitor experiences in our parks and wilderness areas into the future," he said.

"[The shelter] will offer visitors breathtaking views of the lake and iconic Cradle Mountain."

Construction of the new shelter is being undertaken by Devonport-based Vos Constructions, with the building designed by Cumulus Studio Architecture.

It includes a walker registration and information area, interpretive materials, a landscaped courtyard, toilets, and a bus shelter with a turning circle.

It is expected to be complete by mid-2021.

However, the Tasmania Parks social media accounts were flooded with hundreds of negative comments about the shelter when it uploaded the concept design and image of the construction site this week.

One of the shelter's critics is Bailey Henry, a Northern Tasmanian-based photographer who frequently uses Dove Lake and Cradle Mountain in his work.

He believes the shelter will interrupt the natural beauty of the spot.

"Cradle Mountain is a place to escape to the wild, the untouched - to experience the nature for what it is," he said.

"People don't go there too see fancy buildings, they go there to experience the freedom, wide open spaces and beautiful scenery.

"There is a huge community backlash [to this development]."

However, Mr Jaensch said the project - part of the $160 million Cradle Mountain Master Plan - would enhance the tourist experience of Dove Lake.

"Significant infrastructure projects like this are vitally important and will provide contemporary facilities for locals and tourists to enjoy, while supporting our building and construction industry through the COVID-19 pandemic," he said.

"[It will] offer visitors world-class facilities at the entrance to the Tasmanian Wilderness World Heritage Area."

The public consultation period on the shelter was in September and October 2018.

The Cradle Mountain Master Plan also includes a cable car at Dove Lake as well as a Wilderness Village and Visitor Centre, and will replace "outdated and insufficient" infrastructure, Cumulus Studio say on their website.
