Dacorum's largest town, Hemel Hempstead, was one of the original Mark I New Towns designated after the Second World War, and its distinctive split between the older Hemel Hempstead Old Town and the planned New Town — home to the famous multi-circle 'Magic Roundabout' junction — still shapes the borough's housing mix today. That New Town housing generates a steady, high-volume stream of extensions, loft conversions, and garage conversions. Berkhamsted, a historic market town built around its Norman castle ruins and the Grand Union Canal, has a well-preserved conservation area where alterations to older buildings often need planning permission rather than falling under permitted development. Tring, on the borough's western edge, sits at the foot of the Chilterns National Landscape and is home to the Natural History Museum at Tring, with a mix of Georgian market-town housing and semi-rural properties along the Chiltern fringe.
Here's a breakdown of the most common types of construction projects in Dacorum over the past 30 days.
In Dacorum, Extensions are the most common project type, appearing in 82 of the 116 leads tracked in the last 30 days, with Loft Conversions also showing consistent demand alongside Garden Rooms. Projects can fall into more than one category, so these figures don't need to add up to the total.

Hemel Hempstead's New Town housing stock supports a high volume of standard extension and loft conversion work, reflecting a large stock of similarly-aged post-war housing built for London overspill. Berkhamsted's conservation-protected canal-side housing commands higher-spec renovation budgets, while Tring's Chilterns-fringe setting supports a mix of characterful renovation work on older properties alongside standard extensions on its more modern streets. The borough's split character — New Town estates alongside protected historic market towns — gives builders exposure to both high-volume and high-spec ends of the market.
Planning applications highlight upcoming work, giving you a chance to get in touch before builders are shortlisted.
Approved applications can be particularly valuable because the project has cleared a major planning hurdle and may be moving closer to construction.
