One of the country's most famous private schools is to have its premises expanded so girls can attend.
But residents living near Charterhouse in Godalming raised concerns about “developments creeping onto the Green Belt” .
Dozens of people living nearby objected to the planning application for the four-storey boarding houses which will provide 128 extra rooms for pupils and homes for staff.
The development is part of a larger plan drawn up to allow the school to become fully co-educational and eventually take the number of pupils up from 800 to 1,088.
Girls will be allowed to join the school at Year 9 from September 2021.
It is hoped girls will be in every year group by 2023.
Councillors at Waverley Borough Council approved the application.
