Angry residents say a new school being built next to their homes is an eyesore and is breaching their privacy.
Neighbours have joined forces to protest against the development on Doe Hill Lane, Tibshelf.
Jim Cotterill, 76, who lives in a bungalow next to the school site with his wife Anne, 74, said they did not realise the building would be so big.
He added: “We were told we would not be able to see it over our fence. We didn’t know it was going to be like this.
“Our main objection is it’s an eye sore and we won’t have any privacy. It’s right in our face.”
The new 750-school is due to be completed next autumn.
Mr Cotterill said: “We feel we have not been given enough information about this and it has all been done very underhanded.
“So many people are complaining about it.”
A spokesman for Derbyshire County Council, which is leading the scheme, said the school was being built to the approved plans.
He added: “Design steps were taken to minimise the visual impact of the development – including landscaped areas which will take time to become fully established.
“Residents, including Mr Cotterill, were consulted throughout the design and planning process.
“Members of the planning committee discussed residents’ concerns about visual impact along with other issues when they considered these proposals and weighed up all of the potential impacts and benefits.
“Our consultation went well beyond what we were legally required to do and the size of the development was made clear.”
