The development on the site of a former car showroom and vacant office building has been designed by Stanford Eatwell Architects.
It will feature a series of eight low-rise apartment blocks with brick façades, plus a variety of outdoor space including podium terraces, roof gardens, and landscaped gardens.
Isleworth is also set to benefit from the wider £151 million regeneration that is taking place across the London Borough of Hounslow, which is expected to be complete by 2025.
Rebecca Littler, Sales & Marketing Director at London Square, said: “We now have a total of eight prime sites underway across the capital and Isleworth.”
