See the damage in the clip above.

Large accumulations of water, fungus and moisture.

This is what it looks like inside the old town hall right now, where housing is planned to be ready by the summer.

- I have doubts about the construction method, says Thomas Schultz, contract manager at Byggnads fackförbund and S-politician.

- It's nothing strange, we've dealt with it, says the construction company's operational manager, Martin Bernsten.

Byggnads has also received complaints about the working environment for the construction jobs, but they state that there have been improvements as these have been discovered.

For example, certain floors have had to be closed off, as they are considered dangerous to stay on.

No ceiling

The reason for the water damage, according to the construction company Kvalitetsbygg, is that the war in Ukraine and the pandemic caused late delivery times, which in turn meant that the roof was not in place in time for autumn.

- We would have liked to have finished at the end of the summer and we have had delays, which has caused us to get the autumn storms in, says Martin Bernsten.

"Responsible company"

It is what it is, he says.

Now they must clean up, replace damaged parts and dry what has been water damaged before the roof is put in place, so that no moisture builds up in the building.

- We cannot handle it in any other way, but we are a responsible company.

In 2015, Karlstad municipality sold the old town hall to entrepreneur Mikael Solberg.

The sale made headlines for years to come, as critics argued that it had not gone right and that the buyer had to pay an underpriced price.

It is still Mikael Solberg who owns the property, but the extension with three new floors has been outsourced to Kvalitetsbygg as a turnkey contractor.
