Plymouth Community Homes (PCH)

PCH (Plymouth Community Homes) used high-resolution aerial images combined with the Trendspek platform to gain efficiencies for planned maintenance work across the high-rise elements of their large housing portfolio.

ABOUT PCH

As a leading housing association focused on improving community lives. PCH is Plymouth’s largest social housing landlord with over 16,000 properties housing 35,000+ people in Plymouth and the surrounding areas.  PCH also operates as a commercial landlord with 170+ city shops.

Their Challenge​

Managing a large and complex estate, PCH faced escalating costs and limited visibility of the true condition of their buildings. Roofs in particular posed a challenge: traditional inspections were time-consuming, expensive, and carried safety risks for surveyors. Without clear, accurate data, planned works risked being far more extensive — and costly — than necessary.

The Solution

Using drone and LIDAR surveys, we delivered a digital twin of the asset, combined with thermal imaging to help identify water ingress on roofs and external walls. The remote capture removed the need for scaffolding and working at height, whilst providing a level of detail far beyond measured surveys.

Outcomes

>10x return on investment by enabling targeted maintenance instead of unnecessary large-scale roof works

Up to 80% cost savings vs. traditional inspections, with faster capture and fewer site visits

Safer, zero-touch inspections eliminating working-at-height risks

3D interactive digital twins via Trendspek, enabling stakeholders to view, annotate, and plan maintenance collaboratively

Ongoing asset visibility supporting preventive maintenance strategies that typically save 12–18% vs. reactive repairs (RICS)

Cost-saving, safety and efficiency benefits

Hours/days capture time*

Versus the traditional ground/roof-based data capture time of weeks or even months for large assets, saving days/weeks

De-risking data capture

Versus ground or rooftop inspections with ropes, scaffold and towers our aerial capture tools are “zero-touch”

Up to 80% cost saving

Versus traditional manual inspection costs by removing the expense of prolonged capture time, travel time and repeated in-person site visits

Fully digital remote inspection

Versus the traditional survey which does not “see” all of the asset from all aspects and elevations

Millions of data points

Versus ground/roof-based surveys with limited access and finite resolution, allowing pinpoint accuracy across the whole digital twin

3D interactive outputs

Versus the traditional 2D paper-based reports and images which have limited access, coverage and quality

*For areas up to 10,000 or 1ha – roof inspection image capture in one day. Larger areas of up to 100ha are for landscape photogrammetry in one day.
