No drop down kerb to low car to drive over

Would like to report that the person on the end of the small red brick terrace houses in beginning of Chapel Street, have made a drive way to side of their house and now are parking two cars on it, but I note they do not Have a dropped down kerb, I've checked planning to see if it was in forecast to be done and nothing came back, they are driving over a normal pedestrian pavement area with thier cars to access their new driveway and even using the sloped part that's meant for pedestrian use only as has the little raised bumps on floor paving slabs, this constant use if driving over pavement is going to make that area of pavements dangerous soon, I do not know the number of the house but its only a small row of new-ish build terraced houses, red brick, and its the one in the very end of them who caused this. Please look into this. Thanks
