SEGRO Park Green Lane (Formally Heathrow International Trading Estate)
Creating a best-in-class sustainable industrial centre in Cranford, Hounslow
SEGRO Park Green Lane (formally known as Heathrow International estate) is an established estate with a wide range of industrial and warehouse units. It has played an important role in the local economy and jobs growth within Hounslow.
We want to ensure this continues well into the future by proposing estate-wide improvements to meet the highest quality design and sustainability standards and enable modern functionality. Through this, we will create premises to attract a variety of businesses to the area, creating more jobs and opportunities for local residents.
Should you have any questions about our proposals, please get in touch here.

Community Investment
SEGRO has proudly invested in community initiatives in Hounslow for many years and will continue to build on and strengthen this commitment in the years ahead. Working in partnership with Action West London, BUILD, Youth Careers Collective (formerly Spark), and Groundwork Investing in the community, we deliver targeted programmes that create meaningful opportunities for residents.
Our initiatives range from training and tailored employment support to help residents secure sustainable work, to inspiring young people through careers sessions and workshops that broaden awareness of the world of work. During construction we will support local businesses and people to maximise supply chain, training and employment opportunities arising from our developments and invest in environmental improvements that enhance biodiversity and wellbeing across local neighbourhoods.
The site
Designated as Locally Significant Industrial Land (LSIS), the Heathrow International Trading Estate in Cranford, Hounslow occupies a prominent location at the junction of Green Lane and The Causeway (A30). It also benefits from excellent transport links, being only a short walk from both Hounslow West and Hatton Cross stations.
Built nearly fifty years ago, the estate is home to a diverse mix of industrial businesses, from local businesses to international. However, many of the buildings have become dated over time and are now in need of comprehensive modernisation.
