Hi all. I realise if I'm asking this it means I should be getting the experts in but here goes... I've recently purchased a 1930s mid terrace house and plan on knocking through to create a kitchen diner. Its a fairly standard layout - kitchen and dining room at the back of the house with the kitchen narrower and slightly shorter (as you enterr the dining room from the side). I'd originally assumed it was a supporting wall due to the bathroom wall above but on closer inspection with a tape measure the walls don't line up. The joists run parallel to the wall and from what I can see in the upstairs bedroom there's an extra joints on at least one side of the wall ie. The rest in the room are 400mm apart but there's an additonal one 150mm away from the wall edge. What I'd like to know is how can I determine if it is loadbearing. A builder friend suggested putting a steel in anyway to be on the safe side as he said he'd imagine its supporting something but if I can avoid it I'd rather not spend money where's its not needed. Equally, I'm happy to pay what it costs to do it properly. Will building control be able to tell me or will I need to pay for a strucutural engineer
