Construction Trends in Hillingdon
Uxbridge and Hayes have plenty of interwar semis and terraces where loft conversions and rear extensions are the standard job. Ruislip, Northwood, and Ickenham sit further out with larger detached plots, so applications there run bigger - double-storey extensions, outbuildings, and full renovations rather than a single room addition. Around West Drayton, proximity to Heathrow and the industrial corridor also brings through the odd change-of-use or commercial conversion alongside the usual domestic work.
Project Type Breakdown
Here is a breakdown of recent planning submissions across Hillingdon by project type, showing where the work is currently concentrated.
In Hillingdon, Extensions account for the majority of planning applications (127 of 208 in the last 30 days), with Garden Rooms also showing consistent demand alongside Porches.

Planning Approval Times in Hillingdon
In Hillingdon, most planning applications are decided within 8 weeks. Smaller projects like extensions tend to be approved more quickly, while larger developments can take longer.
Domestic vs Commercial Projects in Hillingdon

Demand for Building Work in Hillingdon
Property in Hillingdon costs less than in most inner London boroughs, so a well-planned extension often adds value well beyond what it costs to build, which makes homeowners here more willing to commit to a bigger scheme rather than a token upgrade. The borough also draws a lot of Heathrow and M4 corridor commuters looking for family-sized homes, which keeps steady pressure on older housing stock to be extended or modernised.
