gap between new build and site boundary

[smart51]

What is considered good practice for leaving a gap between the edge of a building and the plot boundary?  Obviously if you build right up to the boundary you have no access for maintenance etc.    Build plots in cities are often at the ends of existing gardens, so you're not next to your neighbour's houses or anything.  Also, if planning says for example 2m between the boundary and the building, is that 2m to the wall or to any roof overhang and guttering?

To the guttering normally, although that is often ignored, and it does matter if very close.

 

If you have room, then 2m is much easier to work with than any less, using proper scaffolding, and just about getting a ladder to the eaves.

The fire rules can be affected too, and you are allowed more windows as the distance increases.

 

For the finished house, a 1m passage is purely functional, whereas 2m allows some planting, Maintenance,.... as for building.
