New Model Building: Guide, Details, and Evidence

The New Model Building (NMB) framework outlines design principles for mid-rise residential developments using low-carbon engineered timber. The goal is to reduce embodied carbon while maintaining safety, durability, and compliance with UK Building Regulations and NHBC standards. This suite of documents—Guide, Details, and Evidence—serves as a comprehensive methodology for building sustainable and resilient timber structures. It covers aspects such as fire safety, moisture management, and structural strategies, providing design professionals with practical solutions to meet regulatory and environmental requirements.

Key Takeaways

• Carbon Reduction: Timber structures offer a 75% reduction in carbon emissions compared to traditional concrete and steel buildings, aligning with climate targets.
• Fire Safety: NMB incorporates multiple layers of fire protection, including full encapsulation of timber elements and the use of non-combustible materials for façades and fire-resistant barriers.
• Moisture Management: Effective moisture control is emphasized through design strategies, site practices, and post-completion protocols to prevent structural damage from water ingress.

How It Can Help You

This set of documents is valuable for architects, developers, and policymakers who are:

• Looking to implement low-carbon, timber-based residential developments.
• Interested in practical solutions for overcoming regulatory and technical challenges related to fire safety and moisture management.
• Seeking a comprehensive, compliance-driven approach to sustainable construction.

Key Learnings

1. Sustainability in Design: Timber, when coupled with a non-combustible façade, provides a viable pathway for reducing carbon emissions in mid-rise residential construction.
2. Regulatory Compliance: The NMB methodology ensures full compliance with UK statutory guidelines, including fire safety regulations, without compromising on environmental performance.
3. Moisture and Fire Mitigation: The documents emphasize the importance of encapsulating timber and maintaining stringent moisture controls during and after construction to ensure the longevity and safety of the building.
