Solicitor's Letter for Access Request

I need a formal solicitor's letter drafted to request access from my neighbor for a building surveyor. The access is needed before and after construction work on a load-bearing wall in a ground floor flat, to create a photographic record. The neighbour is likely to deny but he must be given the opportunity and a time limit of 14 days to respond or it'll be be assumed he denies access,
