Appendix A: Heritage Technical Detail
Full technical data from the 2025 Heritage Conservation Framework — significance ratings, health & safety requirements, thermal upgrading trials, and key professionals.
This appendix supports The Heritage Crisis executive briefing. Return to the executive briefing for the summary.
Significance by Area
| Area | Significance | Condition | Conversion Approach |
|---|---|---|---|
| Compound D (Huts 61–91) | Highest — the only near-complete PoW compound in the UK | Mostly poor | Heritage-sensitive premium conversion. External appearance preserved exactly. “Museum-quality luxury.” |
| Compound C (Huts 41–60) | High — 60% of compound survives | Poor to very poor | Sensitive conversion. Some huts (41, 44, 48) may be replaceable with new Nissen hutting on same footprints. |
| Escort Camp (Huts 21–39) | High — Phase 3 additions (1946–47) | Fair (29–39 recently repaired) | Huts 29–39 already converted to self-catering. The proven template for full luxury rollout. |
| Admin Area (Huts 1–20) | High — includes Detention Block, Camp Reception | Mixed | Officers' Mess venue, reception, museum, spa. Heritage interpretation hub. |
| Compounds A & B (cleared by MOD) | Archaeological interest only | N/A (cleared) | New-build Nissen huts on original footprints. Additional capacity. Requires HES agreement. |
Health & Safety — Pre-Conversion Requirements
| Issue | Status | Action Required |
|---|---|---|
| Asbestos | Present in Hut 20 roof, insulation, fire equipment, various locations | Review and update Asbestos Management Plan. Survey all huts before conversion works begin. |
| UFFI insulation | Deteriorating in many huts. Pieces blowing around site. Health risk. | Maintain register. Prepare removal method statement. Budget for controlled removal during conversion. |
| LPG gas | Installations throughout camp. No historic value. | Framework recommends decommissioning and removal. Replace with modern heating in conversion. |
| Electrical | Ageing installations. Unclear responsibility. | Full EICR for all huts. Mandatory for self-catering from 2023. Budget £2K/year ongoing. |
| Flood risk | NE corner: high risk from surface water | Factor into conversion phasing. Prioritise Escort Camp and Admin Area (lower risk). |
Thermal Upgrading
Nissen huts were designed as an improvement on tents. Thermal performance is a known challenge. The framework notes two upgrade approaches already trialled:
- Hut 1: John Gilbert Architects (Glasgow) — sheep's wool, recycled plastic wool, hemp batts
- Huts 29–39: James F Stephens & Partners (Glamis) — sensitive thermal upgrading within conservation constraints
The framework recommends monitoring performance of both methods before replicating. Roger Curtis, Head of Technical Resources at HES, may support monitoring as part of their historic buildings research programme.
The framework also suggests considering low-cost renewable energy as an alternative or complement to fabric insulation — directly supporting the solar micro-grid strategy.
Key Professionals Identified
| Professional | Role | Relevance |
|---|---|---|
| James F Stephens & Partners (Glamis) | Conservation-accredited architects | Designed Huts 29–39 conversion. The obvious choice for wider conversion brief. |
| Onecall Ltd (Perth) | Contractor | Developed Nissen hut repair skills on Huts 29–39. |
| John Gilbert Architects (Glasgow) | Thermal upgrade specialists | Insulation trials on Hut 1. In-situ monitoring expertise. |
| Roger Curtis (HES) | Head of Technical Resources | May support thermal monitoring as part of HES research programme. |
| Jody Blake (PKC) | Conservation Officer | Contact for Conservation Area designation discussion. |
| Gareth Pugh Steel Framed Buildings | Modern Nissen hut manufacturer | £7,650/hut (9-bay kit). Option for replacing worst huts or infilling Compound B. |
Conservation Area Designation
The framework notes that PKC is open to discussing whether Cultybraggan should become a Conservation Area. Benefits:
- Stronger funding eligibility (especially HES Heritage & Place Programme)
- Control over privately-owned huts (some sold without conservation burdens)
- Raises heritage profile nationally
- May enable access to additional funding sources
This should be pursued alongside the luxury conversion — it strengthens every funding application.
