Plans to build 11 family homes in Old Windsor were refused by the Royal Borough of Windsor and Maidenhead over fears residents would be at risk from flooding.
Applicant GSMD Ltd was seeking to build 11 houses by demolishing buildings on a brownfield site at 95 Straight Road.
Councillors on the Windsor rural development control panel went with planning officers recommendation at Old Windsor Day Centre on Wednesday night.
The proposal was supported by Old Windsor Parish Council but concerns were raised by the council about the escape route for residents if the area was flooded.
Cllr Malcolm Beer, speaking in support, said he was concerned about flooding but didn't think residents would be at risk and the area had never been flooded before.
