Proximity of gravel to the surface of the near-flat land — see
Hounslow Heath — restricted productivity and diversity of plant life across the constituency and caused initially cheap land values, a factor which led the area to significant industrial use since the mid-19th century and construction of
London Heathrow Airport, the area's largest employer including its many import/export businesses. The area at
central Feltham and on the busy and the somewhat slower (to Central London)
Piccadilly line at two tube stations in the north connects into London and the latter also connects to Heathrow Airport. This part of the Borough of Hounslow since 1955 has the great majority of its of
Metropolitan Green Belt, forming an immediate
buffer zone for all of Greater London. The
M4 motorway and dualled parts of the
A4,
A30 and
A316 roads run close to a significant minority of homes. Many local initiatives seek to abate pollution in the Borough and other have successfully attracted major retail and leisure into Feltham and Hounslow, both of which were large villages rather than
market towns in the 18th and 19th centuries. The constituency is lower on the socio-economic scales than those in neighbouring Brentford and Isleworth. There is higher proportion of
social housing, though unemployment is proportionally low by London standards. The seat also includes the western part of the slightly larger urban centre, Hounslow. The constituency is to the southeast of
London Heathrow Airport where many local constituents work, and small storage, distribution businesses are a feature of this half of the borough, as well as light industry and office accommodation. Next to
Cranford on the
A4 Bath Road are most of the luxury airport hotels, and an imposing 1998 conversion of an office tower into a hotel in
Feltham's
linear town centre. The seat includes a
Young Offenders Institution, small business and industrial park and a
motorway service station. Across all wards, car ownership is much higher than the London average; for the small proportion of people (who work in the
City),
Feltham railway station,
Hounslow West Underground station,
Hounslow Central Underground station and
Hatton Cross Underground station provide good links from several areas to the capital. == Political history ==
