Bespoke steel entrance doors for Harpenden homes
Harpenden in AL5 regularly tops surveys as one of the best places to live in Hertfordshire, its long High Street and wide Common giving the town a quintessentially English character. The Harpenden High Street and Common conservation area preserves Grade II listed cottages, Georgian frontages and the Grade II listed St Nicholas Church. Premium residential roads including West Common, Crabtree Lane, Rothamsted Avenue, Amenbury Lane and Topstreet Way carry substantial Edwardian villas on large plots, while Kinsbourne Green, Wheathampstead and the Lea Valley edges add further detached stock. The Southdown, Batford and Roundwood areas supply inter-war and post-war family detached housing, and the Rothamsted Research estate frames the town's southern edge with AONB-adjacent rural properties. SteelR bespoke steel entrance doors bring a new dimension to these properties with handcrafted designs, BS EN 1627 RC4 as Standard with LPS 1175 SR3 (Enhanced upgrade), LPS 1175 SR4 (Commercial-grade) and LPS 1673 (Ultra-high, by enquiry) upgrades available, and fully bespoke RAL colour and European-sourced ironmongery. AL5 surveyed from our Ickenham workshop.
