Hi there, hope everyone is well. I'm looking to buy a property that looks like it needs a bit of work done and not sure how serious it is. I can email pics if it helps.

Its a basement flat of a Georgian terrace and in the light well bit facing the main road, there is a large gap in one of the walls supporting the stairs leading to the raised ground floor flat adjacent to mine. This gap is all the way across the bottom of that wall approx 80 X 35cm where all the render or plaster looks like it has crumbled and there are thick slices of render/ plaster on the floor. Doesn't appear to be an actual wall or broke or stone behind the hole so looks like it's just the plaster or render that has crumbled.. I can't currently access the space to see behind it. Also a couple of long cracks running up the wall. Not sure if this is structural or how easy it is to repair. Really grateful for your thoughts. Thanks.James
