On the outside the house is boarded up and derelict but Substormflow discovered a section of the culvert underneath it had collapsed and a large hole had appeared in the interior floor.

Rossendale council and the Environment Agency said they have been working together on the issue, but they say the culvert is the responsibility of the landowner.

The EA confirmed they have developed a contingency plan to mitigate the flooding risk if the culvert collapses further.

The culvert is said to be the responsibility of the landowner

"It's not every day you get to see up into somebody's front room from a culvert," he said.

"Occasionally you find older culverts that have a deformed profile or a few blocks missing.

"This is the first major collapse I've come across and it's certainly unique with the building being straight above," he continued,

"The rest of the culvert appeared to be in reasonable condition though.

"The rest of the culverts along the river were fairly typical though there was a stone weir further upstream which made a good spot for a photo."

An Environment Agency spokesperson said: "The Environment Agency has been working with Rossendale Borough Council on this issue. The culvert is the responsibility of the landowner.

"The Environment Agency will look to implement works to manage the risk of flooding at the site once it is safe to do so.

"We have also developed a contingency plan to mitigate the risk of flooding should the culvert collapse."

Substormflow says the house is a 'unique find'

A United Utilities spokesperson said they have no responsibility for culverts, adding: "We have previously attended to check our sewer within this location which is in good condition and free from any issues."
