Planning permission

A friend of mine is thinking of building a two storey extension on to the side of her house.
It has been suggested that the application for planning permission might be knocked back
as it would block out light to the neighbours house which already has a similar extension.
Does anyone know of any cases where a planning application has been rejected due to the
problem of access to light?

If it's to the side of the house I'd think they would be OK. If there is another one there similar, it shows they were allowed. Even if they object, it can still be ignored. Look at this below for more info and try googling 'right to light law scotland'.

Have a look here (http://www.burnyourbonus.co.uk/house/planning.html)

Some points on the page say:

They only have a right to light through their windows if the windows have been there for at least 20 years.
- Although each case is taken on its own merits, there is a general rule of thumb that can be used to decide if they are likely to have a case. Take a line from the bottom of their window at 45 degrees upwards and towards the blocking construction. If it blocks the line then you could be in trouble.
- Other factors need to be taken into account such as their use of the illuminated area.

Hot Tip:A serious case of "right to light" is a cash cow for lawyers. If there is a possibility of it arising, talk to your neighbours before you submit for planning permission.

Thanks for the information, I'll pass it on.
