Property development
in Hertfordshire.
Hertfordshire benefits from its position immediately north of London, with fast rail services from multiple towns into King's Cross, St Pancras, and Liverpool Street. The county has a strong bio-science sector centred on Stevenage, a growing film industry around Leavesden and Elstree, and established commuter markets in St Albans and Harpenden that command premium values. Major housing growth is planned at Harlow and Hemel Hempstead.
The Hertfordshire property market recorded 8,167 residential transactions over the past 12 months, with a county-wide median sale price of £446,250 - £161k above the UK average. Prices have shown growth, with a year-on-year change of +1.2% across the county's 10 principal towns.
New-build completions totalled 87 over the same period, representing 1.1% of total transactions. Development activity is moderate, suggesting potential for increased supply to meet demand.
