Auto locksmith in Mark Hall
Mark Hall in CM20 was the first neighbourhood built in Harlow, north-east of the town centre and close to Harlow Town station and the Templefields estate. Station parking generates lost key calls from commuters, and Templefields generates commercial work. The housing itself is early new town design with communal greens and parking bays rather than individual driveways.
