Saw the project all the way through to approval from Local Council

We had a previous structural engineer that made mistakes and cost us thousands which we fired. We got Richard from RN in, he gave us a competitive price, and got us back on track straight away. He dealt with the council at every stage of the approval process for us, the council were very slow and kept putting hurdles in our way. One day the council contacted us to let us know our new extension with its RSJ's had all been approved, we were over the moon. I cant thank Richard enough for his dedication and commitment to getting us the Council approval for our structure which a previous structural engineer had botched up.
