It shows the proposed Nishkam School West London building on the old Conquest Club site (also known as the old Pyrene sports club) between Syon Lane and Wood Lane, in Osterley.
Also featured are the new facilities planned for Grasshoppers RFC, which is being asked to move from its current grounds in nearby MacFarlane Lane to make space for another new school.
The plans show a shared entrance off Syon Lane, with three rugby pitches on the club's half of the land and a football pitch and multi-use games area on the school's side.
The photo was obtained by Cllr Tony Louki, who claimed the plans were presented in a meeting held on April 28.
Mr Louki said the photo was passed to him by a disgruntled resident who told him: "This little green village is slowly being transformed into an industrial area with no proper infrastructure and inadequate planning."
Osterley and Wyke Green Residents' Association has also raised concerns about the impact of the proposed Nishkam building, which it says would worsen congestion on local roads and mean the loss of more protected Metopolitan Open Land.
Mr Louki said he was told there was also talk at Tuesday's meeting about plans for another new school near the Wyevale garden centre a short distance up the road.
Nishkam, which will have 1,400 pupils aged four to 18 when it reaches capacity, plus nearly 100 nursery children, has been based in an old office block in London Road, Isleworth, since opening two years ago.
The school has yet to submit a full planning application and has not responded to getwestlondon's request for a comment, but it is understood the land has already been purchased for the school by the Education Funding Agency (EFA).
Grasshoppers has yet to comment publicly about the proposed move to smaller grounds, where it is understood improved facilities would be offered as a sweetener, but the club is consulting members.
The HIP (Hounslow Improvement Partnership) School, a new secondary free school set up by headteachers in the area, which is due to open in 2017, is in line to move to Grasshoppers' current grounds.
Chiswick School headteacher Tony Ryan, who is heading up the HIP School plans, said there was a shortage of suitable sites in the area, where he said more secondary school places were badly needed.
