Construction Services in Hertfordshire

Hertfordshire sits directly north of London and has been shaped by its role as the capital's residential hinterland since the Victorian era. The county contains some of the Home Counties' most sought-after addresses — St Albans, Harpenden, and Radlett attract buyers seeking space, heritage, and excellent school catchments. The county's Green Belt is among the most extensive in the Home Counties, preserving Hertfordshire's character but creating a planning environment that rewards expertise and knowledge of what the various district councils will accept.

Our Hertfordshire construction team delivers across the full county — from urban terraces in Watford and Hertford to substantial family homes in St Albans's conservation areas and rural properties across the county's quieter districts. We bring London-grade planning expertise and build quality to every Hertfordshire project, managing the entire process from concept to completion.

Planning in Hertfordshire

Hertfordshire is administered by 10 district and borough councils. Green Belt is extensive across much of the county, particularly in the southern and western areas bordering Greater London — St Albans, Welwyn Hatfield, Dacorum, and Three Rivers districts all have significant Green Belt coverage.

St Albans City Council is known as one of the most conservation-focused local authorities in the Home Counties, with an extensive network of conservation areas and listed buildings reflecting the city's Roman and medieval heritage. Harpenden, though within St Albans district, has its own conservation areas. Other significant conservation areas include Hertford's historic town centre, Hitchin, and Berkhamsted. Outside Green Belt and conservation areas, standard permitted development rights apply across Hertfordshire's residential neighbourhoods.

FAQs — Construction in Hertfordshire

How strict is St Albans's planning authority?
St Albans City and District Council is one of the most conservation-focused planning authorities in the Home Counties. The city has extensive conservation areas covering much of its historic core and surrounding residential neighbourhoods. Applications affecting listed buildings or conservation areas receive detailed scrutiny, and the Council's conservation officers have high design expectations. We recommend pre-application advice for any St Albans projects in sensitive locations.
Does Green Belt affect most Hertfordshire properties?
Green Belt is extensive in southern and western Hertfordshire. However, most existing dwellings within Green Belt can be extended by up to 25–30% of their original size, subject to design quality and the specific policies of the relevant district council. New builds within Green Belt are more restricted. We assess the constraints on your specific property before advising on achievable scope.
What construction services do you provide in Hertfordshire?
The full range: single and double-storey extensions, loft conversions, basement conversions, full renovations, new builds on suitable plots, and specialist heritage work for listed buildings and conservation area properties. Our experience with London's demanding planning environment means Hertfordshire's district councils hold no surprises.
