The founders of Floreat Brentford, a free school which opened last autumn on the ground floor of a tower block, want to move to new purpose-built premises in Leyton Road, Brentford.
A number of homes are also planned for the eastern end of the plot, which backs on to the railway line near Brentford station, though the developer has yet to reveal how many.
Detailed proposals for the school building have now been unveiled by Hodson Developments, which is working with the Education Funding Agency and Floreat Education Academies Trust to develop the land.
School would be completed in time for September 2018
The developers say designers are still working on the design of the homes, but early sketches suggest they would be around two storeys tall on the street front, increasing in height towards the boundary with the railway lines.
The school building would have three storeys and its grounds would include a multi-centre play area.
The developers intend to submit a planning application this September and to gain approval by January next year.
The school would take around 10 months to complete, ensuring it is ready for September 2018, and the homes would take approximately 18 months to build, it is claimed.
The school, which will have 240 pupils when it reaches capacity, had planned to open in a temporary building on Brent Lea Recreation Ground last September.
But public opposition to the loss of open space meant it was forced to hurriedly seek an alternative location.
The school's founders settled on Trico House in the Great West Quarter development, where there is no outdoor play area on site for pupils.
