The room was discovered during renovation work in a terraced house.

It appeared to have no corners. The walls curved subtly, meeting without angles.

The space felt smaller on the inside than its external measurements allowed.

Workers reported dizziness after standing inside for more than a few minutes.

The room did not appear on any original plans.

It was sealed behind plasterboard before the property was sold.

The current owners are unaware it exists.
