Hertfordshire, Harpenden
Large plots, strong ceiling prices and a steady demand for serious extensions.
Building in Harpenden
Harpenden has been one of our busiest towns for years. Generous plots on the roads off Luton Road, Southdown and Kinsbourne Green support the kind of extension and renovation work that changes a house permanently rather than cosmetically.
Ceiling prices here justify proper specification, which is why so many Harpenden projects end up as whole-house reinventions: extension, remodel, new services and landscaping in one programme.

FAQs
Typically £2,200 to £3,200 per square metre, with wrap-arounds and two storey work towards the middle of that range and basements above it. Remodelling the existing house is usually part of the budget too.
