Developer erected his fence within my yard, costing me.

The developer would have known about access agreements. And would have had one.
Although his version may not have been best for your interests.
A solicitor that specializes in property related legal advise is best - in my experience.

Another issue is insurance for any event that happens on your property. You should not be liable for any risk

I was in a similar situation. Developers are cheeky and try to get things at no cost and risk to them. My solicitor advised me to call the police for trespass if developer came on to my property and access agreement was not signed.

 

I hope you got a security deposit for use in case the developer doesn't restore the site. Many stories of developers riding off into the sunset and leaving the corporate entity with no financial assets and not worth chasing. An indemnity is great ... on paper.

 

Talk about pushing the boundaries. Might have to talk to a lawyer with this one.

 

Would also be hard to jump a fence like that with a bottle of rip van winkle in a paper bag and the lawn mower..

 

That's why I'm totally against this type of behaviour.
