When starting a large renovation project it can be very daunting at first, I mean where do you start? The first place I would always start, is ask yourself, does the structure need securing? Once the bones of the building are secure and not moving, then make sure everything is water tight. You will find there becomes a natural order from then on. One job generally leads to another once you start ripping things out. Try and divide the room/ building into smaller sections, do the upstairs spaces first, then move downstairs maybe. Look at each room and try and make a list of what needs to be done. This might mean stripping everything back to the bear brick to find out exactly where all the damage might lie! This isn’t necessarily a terrible thing to do or a bad place to start, once everything is out of the way you can generally see the wood for the trees, or the brick from the rot!
