Up to 12 Gypsy and Traveller families will be able to live on land north of Burwell.
The site off First Drove already had planning permission for six pitches for Gypsy and Traveller families, but had not been fully built out.
Owner Thomas Pateman asked East Cambridgeshire District Council for permission to increase the number of pitches allowed up to 12.
Each plot could include one mobile/chalet home, one touring caravan and a day room.
The brownfield site has various commercial uses but was described in the application as “vacant and untidy”.
It said: “Mr Pateman and his family were all born Gypsy/Travellers. The proposed six additional pitches – 12 pitches in total – will only be occupied by Gypsy/Travellers.
“It is proposed that Mr Pateman will live on the first plot and act as manager for the site.
“As he owns the site he will take overall responsibility and ensure it remains tidy.
“He has also endeavoured to take control of the fly-tipping issue along the section of First Drove nearest to his development.”
A paddock area and pond will be designated at the back, creating a play area for children and an unsightly cold store building demolished.
Council officers said the authority was unable to “adequately demonstrate” that it has a five-year supply of pitches for Gypsy and Traveller families, which was a “significant” factor.
The development would “not significantly detract from the rural and open character” of the area or lead to any “severe harm” from transport or noise, it noted.
Councillors approved the plans.
