Local Project Patterns We Plan For
Hertfordshire's planning landscape is shaped by six separate local planning authorities, each with distinct conservation-area designations, Green Belt boundaries and design guidance. Our surveys across the county consistently return to the same practical questions: which authority applies, what are the local character requirements, and which route — permitted development or full application — is the right starting point.
| Local property pattern | Scope we commonly plan | First feasibility check |
|---|---|---|
| 1930s semis and detached homes in Hertsmere (Borehamwood, Radlett) | Rear extension or loft conversion | Permitted-development limits, roof form and Green Belt boundary |
| Period properties in St Albans, Harpenden and Hertford | Sympathetic extension, refurbishment or loft conversion | Conservation-area designation, materials and Article 4 restrictions |
| Garden city homes in Welwyn Garden City | Carefully designed rear extension or internal remodelling | Conservation-area character policy and roofline impact |
Why the Local Context Changes the Scope
Working across six planning authorities means we do not assume one county-wide rule applies. A permitted-development rear extension in Hertsmere may require a full application in St Albans, and a design that satisfies Watford Borough's guidance may need a different materials approach in Welwyn Hatfield. We check the relevant authority's position at survey stage, before scope and cost are agreed.
These are recurring local feasibility and planning considerations, not a substitute for a property-specific survey, title review, or planning assessment.
