Residents of a north-west Tasmanian suburb say excavations for a state government housing project have caused their land to start slipping downhill.

Some of the residents are even blocked from accessing their own sheds.

Homes Tasmania says it takes concerns seriously and is working to remediate the situation.

Everybody needs good neighbours, but a state government housing project in Tasmania's north-west is eroding the foundations of friendship before a single home has been completed.

Residents of the Burnie suburb of Romaine say they have had access to parts of their own backyards restricted as land at the shared boundary has started crumbling onto the Homes Tasmania development.

Temporary fencing, complete with "KEEP OUT" and "DO NOT ENTER" signs, has been erected in the residents' backyards this week, following heavy rainfall, blocking some from even accessing their own sheds.

Homes Tasmania said monitoring was in place to ensure safety, and that an "alternative construction methodology" was being implemented.

Roslyn Avenue resident Geoff Dyke said earthworks started at his western boundary earlier this year.

He said there was now a two-to-three-metre drop off the edge of his backyard where the developer removed his existing fence.

Mr Dyke said the developer told him a retaining wall was going to be built to prevent further collapse, but he had been given no timeline for when that would be complete.

In the meantime, the temporary fencing blocks the pathway between his garage and western boundary.

"[We] mostly can't access the backyard, only through the house," Mr Dyke said.

Despite the hassle, Mr Dyke appears to be more bemused than annoyed by the ordeal.

Having lived at the property for more than three decades with his wife, he was optimistic the issue will be rectified.

"We've been here 30 something years … so another 12 months won't matter," Mr Dyke said.

He said there had been little information from the developer or the government about how the situation would be rectified.

Next door, Jacob Carpenter is more frustrated by the situation as he is concerned about safety issues for his children and the family dog in the backyard.

He has also lost access to a strip of land along his back boundary
