This project marks an exciting milestone: our first public tender win. The Council has empowered local, women-led, and sustainability-driven businesses like ours to participate and make a meaningful impact. This approach is reflected in the social value outcomes we measure across our projects.

Project

This project delivers new affordable homes in Greenwich, designed for the people who live, work, and grow in the community. Matter provided structural engineering expertise, focusing on low-carbon, durable, and flood-resilient design to create long-term value for residents and the local authority.

The development integrates sustainable practices at every stage, ensuring both social and environmental benefits.

 
 

Brief

Matter was appointed to carry out a visual inspection and coordinate a specialist timber survey to report on the building's current state. The project aims to:

  • Provide advice regarding any immediate structural risks to the building and its users.

  • Propose a pragmatic repair and maintenance strategy to enable the building to remain in use for the next 5 to 10 years.

  • Identify opportunities for the client to carry out cost-effective, non-specialist maintenance independently.

 
 

Challenges

  • Lack of Original Records: No original structural drawings were available, requiring us to use historical construction diagrams and on-site visual evidence to understand the load paths.

  • Environmental Exposure: Decades of weathering had caused localized wet rot in external secondary structures, including decking and pergolas.

  • Underground Access: Limited visibility of the floor joists and certain foundation elements necessitated a cautious approach to inspection.

 
 

Solution

  • Specialist Timber Survey: Partnering with Timberwise to identify specific areas of decay and provide a targeted quotation for resin-based repairs.

  • Stability Confirmation: Verifying that the primary structural posts and foundations remain in good condition, ensuring the building’s overall integrity.

  • Prioritised Remediation: Developing a four-tier classification system (Essential, Recommended, Ongoing Maintenance, and Optional) to help the client manage their budget effectively.

  • Moisture Management: Identifying roof leaks and plumbing-related damp to be addressed before they impact the primary timber frame.

  • Long-term Durability Strategy: Recommending a five-year cycle for protective staining to prevent future weathering and extend the life of the timber facade.
