I would like a room built inside another one of my rooms for sound proofing. It’s going to be a music room.

Hi, I’d like to soundproof the partition wall between my house and the neighbour. Total price to be discussed. It’s a townhouse made of hebel. I don’t really hear them talking, but can hear when they walk upstairs or slamming the door, probably structurally/frame bonded. The option im after is decoupling the wall. Installing a new wall on the existing wall with insulation in between. Are you able to provide the quote for 4 walls. 2,4m ceiling, one large wall on ground floor 5m wide. 3 small walls 3.5m wide. I will repaint, reinstall skirtboard, and reinstall the robe if taken off. New wall does not need to be corniced.

We need 2 doors hung to close off a room as an office. Soundproofing too. No current doors in place so would need jambs?
