My next door neighbour has had a new 7 ft fence erected along the boundary of our front gardens. Is this legal? I think there is a limit a height a fence can be erected in a front garden.
You are correct. There is a limit to any wall or fence in front of the building line in any property. Such a wall or fence must not exceed two metres and, in some cases, one metre in height.
In many modern properties the frontages are left “open plan” and any building in front of the Building Line is prohibited. This maintains a modern open plan environment on most new residential estates.
As your neighbour has already erected such a fence then you should contact the planning department as a matter of urgency.
