Building in Hertfordshire: what to know
Garden cities and new towns
Welwyn Garden City and Letchworth were built to strict design principles, and some of their estates have extra controls on extensions, windows and front gardens. Stevenage and Hemel Hempstead estates often carry planning conditions too. We check these before designing anything.
Metropolitan Green Belt
Most of Hertfordshire’s countryside is Green Belt. Householder extensions are often possible, but size limits and planning policy matter, especially for outbuildings and garden rooms.
Historic town centres
St Albans, Hertford and Hitchin have extensive conservation areas and many listed buildings. We work sympathetically and help you get the right consents in place.
Commuter homes that work harder
Many Herts homeowners want space to work from home. Garden offices, fitted storage, garage conversions and kitchen-diner extensions are some of our most common projects here.
Planning and building control
In Hertfordshire, planning and building control applications go to your district or borough council. We check the rules for your property before any work is priced.

Builders in Hertfordshire: common questions
Which parts of Hertfordshire do you cover?
We work from Watford and St Albans to Stevenage, including Hemel Hempstead, Harpenden, Borehamwood, Potters Bar, Hatfield, Welwyn Garden City, Hertford, Cheshunt and Hitchin. Call us with your postcode if you’re elsewhere.
I live in Welwyn Garden City. Are there extra rules?
Parts of Welwyn Garden City are covered by an Estate Management Scheme, which needs separate consent for many external changes, on top of planning. We’ll help you check before you commit.
Can I build a garden office in the Green Belt?
Often, yes, within permitted development limits, but rules on size, height and position apply. We check your plot and the planning history before recommending a design.
