Historian Christopher O'Regan and Erika Åberg, building conservation counselor, help curious owners of old houses. House with exciting history.

At the same time, a building antiquity will find out more about the building's historical history, partly to provide advice and tips on how to renovate it, but also to conduct some building-related renovations that may make a difference to the house's character.
