Margrave's house (The Witcher 3: Wild Hunt)

Stuck on the passage of Dijkstra's quests. He sends to the house of the margrave, there is a cleaver's refuge nearby. I found the house, I need to inspect it by sq. I can't get inside in any of the three moves. Two doors are stupidly closed, and the entrance from the backyard, clogged with boards, does not break through the sign of Aard. What to do?
