British High Commissioner’s Residence, Wellington – Hazardous Materials Removal & Renovation
Client: British Government – Foreign & Commonwealth Office (High Commission)
Location: Wellington, New Zealand
Project Type: Capital Project – Major Alterations & Additions (Residential / Diplomatic Asset)
Project Value: AUD $1.56 million
Project Duration: January 2017 – September 2017
Role: Head Contractor – Program Director
Strategic Objective
The British High Commissioner’s residence in Wellington is a sovereign diplomatic asset—a State property representing the British Government and people.
Following the identification of banned construction materials within the residence, including lead‑based paint and asbestos, the mandate from the British Government was unequivocal:
remove all prohibited materials from British Government properties and restore safe, compliant occupation.
The objective was to eliminate all hazardous materials, achieve full compliance with both British and New Zealand regulations, and return the residence to full operational readiness—while preserving its function, dignity, and representational role.
The Challenge / Need
Sustainable construction practices were not widely adopted at the time the residence was originally constructed. Over time, this resulted in legacy materials now considered hazardous.
Key challenges included:
- Presence of lead and asbestos within an actively occupied diplomatic residence
- Zero tolerance for exposure risk to occupants, staff, or contractors
- Requirement to comply simultaneously with British Government standards and New Zealand regulatory frameworks
- Delivery within the constraints of diplomatic schedules and security protocols
- Preservation of the architectural character and functional integrity of a high‑profile State property
Any misstep would have carried health, reputational, and diplomatic consequences.
Project Scope
The project encompassed full investigation, remediation, and restoration, including:
- Comprehensive hazardous materials identification and testing
- Lead‑based paint and asbestos removal and disposal
- Structural rectification and reinstatement works
- Building services upgrades to improve safety and air quality
- Regulatory certification and safety documentation
- Full handover to diplomatic operations
Our Approach
A risk‑elimination, compliance‑led delivery model was applied—designed specifically for high‑consequence, sovereign assets.
Key elements included:
- Detailed Site Assessment: Identification of all contamination zones and risk pathways
- Specialist Hazard Collaboration: Engagement with accredited hazardous‑materials consultants and testers
- Phased Remediation Strategy: Sequencing works to ensure zero exposure risk at all times
- Stakeholder & Diplomatic Alignment: Continuous engagement with British Government representatives to align scope, timing, and access
- Dual‑Jurisdiction Compliance: Management of parallel approval pathways under British and New Zealand regulations
I led the delivery as Head Contractor Program Director, providing single‑point accountability for safety, compliance, and execution.
Risks and Challenges
Key risks requiring deliberate management included:
- Ensuring zero exposure to hazardous materials for occupants and workers
- Managing decontamination within a live diplomatic environment

These risks were mitigated through disciplined planning, certified removal processes, and uncompromising safety governance.
