Most Common Project
Wiltshire's construction market is shaped by a mix of historic cities, market towns, and one very large constraint: Salisbury Plain, the largest military training area in the UK, covers around 11% of the county's land and restricts development across a significant stretch of central Wiltshire. Salisbury itself, home to a cathedral with the tallest spire in Britain and an original copy of the Magna Carta, has an extensive conservation area where alterations to older buildings often need planning permission rather than falling under permitted development. Devizes, built around the Kennet and Avon Canal's Caen Hill flight of 29 locks, and Marlborough, known for its broad historic high street, both keep a similar protected market-town character. Trowbridge, the county town, and Chippenham generate a steadier flow of standard extensions and loft conversions on more typical suburban housing.
Here's a breakdown of the most common types of construction projects in Wiltshire over the past 30 days.
In Wiltshire, Extensions are the most common project type, appearing in 165 of the 397 leads tracked in the last 30 days, with Garden Rooms also showing consistent demand alongside Heritages. Projects can fall into more than one category, so these figures don't need to add up to the total.

Based on planning applications submitted over the last 30 days.
Among applications tracked by BuildAlert in Wiltshire, the median time from submission to decision is 8 weeks. Smaller projects like extensions tend to be approved more quickly, while larger developments can take longer.
Based on approved applications with recorded decision dates over the last 3 months.
In Wiltshire, 78% of planning applications are domestic and 22% are commercial. Both segments offer opportunities depending on the scale of work you take on.
Wiltshire's rural character and the presence of Salisbury Plain keep new-build activity more limited than in many comparable counties, pushing construction demand toward extending and renovating existing homes. Salisbury, Devizes, and Marlborough's protected historic cores support higher-spec renovation work, reflecting both conservation requirements and generally higher property values in those towns. Trowbridge and Chippenham's more typical suburban housing stock produces a steadier, more standard flow of extension and loft conversion work.
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.
Filter by estimated project value to focus your outreach on jobs that match the size and type of work your business takes on.
