There is a sign on Grange Lane says "Honingham Thorpe, PRIVATE No right of way, Business Park & Farm Only 1000m ahead". I've updated the gate to a swing_gate and fence, there's a second sign by the gate says "Honingham Thorpe, STRICTLY PRIVATE, No entry to unauthorised vehicles, Visitors by appointment only". The swing gate was open this afternoon but has been closed in the past, as I walked past I saw a tractor use the way. 

There is another driveway and gate (Node: 2834066532), into Honingham Thorpe off of Norwich Road. A sign here states "Visitors strictly by appointment only". I saw a couple of vans enter, this looks like the main entrance.

There is a large board at each gate listing the businesses on site. I have photos of the signs. The ways are correctly signed.
