Hertfordshire offers remarkable architectural diversity. The world's first garden cities—Letchworth and Welwyn—have strict design guidelines to preserve their pioneering vision. St Albans' Roman and medieval heritage creates particular sensitivities around its historic core. Meanwhile, villages across the Chilterns Area of Outstanding Natural Beauty require careful integration with the protected landscape.
Our experience navigating these varied requirements means we can advise on what's achievable from the outset. We work with local conservation officers, understand material specifications for sensitive areas, and have a proven track record securing planning approval for ambitious projects across the county.
