Building regulations, how close to boundary?

Building Control shouldn’t have told you that you couldn’t do that as they don’t get involved with the PWA. Unless your BCO was being a little more helpful than others?

Planning comes before Building Regulations and the PWA. If the LPA say no part of your building or structure should encroach the boundary, then that is what you should follow. Foundations can be designed as eccentrically loaded so the wall could go as close as 25mm.

Planning approval for an extension with a wall on the boundary line does not automatically grant you approval to build the foundation across the boundary, irrespective of what the existing situation was. It was permitted before (i.e. when the original houses were built) as it wasn’t a party wall then.

If your house is attached to the neighbours, you can build up to and over the boundary under the party wall act.  

well if this is true then it would seem I was wrongly informed by building control (not surprised), and I could have rightly built it right on the boundary where I wanted it. however, that would have meant falling out with the neighbors as they didn't want it past a certain point, and this 6" of land was seemingly very important to them

That isn't Building Control's job!  

After the stuff I've seen passed recently, I'm wondering what their actual job is.  

Building right up to the boundary is a bit of an enigneering and maintenance problem for the neighbours in future.  I'm not talking about building the wall on the boundary line, giving them no benefit of the wall but impinging on their space with foundations, I'm talking about continuing the party wall so the actual wall is shared and they have the benefit to build off it themselves in future.

How would that work in the OP’s case if they’re going down the PD route? Ownership certificates are not submitted with CoL applications assuming the OP would be going down that route. In other words, can you build a PD extension that encroaches a boundary?

Thinking about this again, it's a shared wall so surely it also falls under the neighbour's PD rights.  They're actively involved in the PW process.
