It was led by City of Edinburgh Council in collaboration with Scottish Futures Trust, Offsite Solutions Scotland, BE-ST, Edinburgh Napier University, University of Edinburgh, and regional partners of the Edinburgh and South East Scotland City Region Deal.
1. Timber MMC delivers homes faster
Timber-based systems are particularly well suited to offsite manufacture. Structural components can be factory-produced while site preparation takes place, reducing programme times and weather-related delays. Scotland has already demonstrated the scalability of this approach, with timber-frame construction now accounting for more than 90% of new homes.
For local authorities and housing providers, faster delivery means earlier occupation and quicker access to rental income. The next major step for Scotland will be to do more in the factory, such as pre-insulating the panels, pre-installing windows and doors or adding an external finish. This is taking place already.
2. Timber supports industrialised construction and better quality
Amid our chronic skills crisis and quality issues, the EHD programme proved the value of standardisation and Design for Manufacture and Assembly (DfMA). The project partners developed a series of standardised-yet-adaptable housing typologies designed specifically for offsite production. This allowed greater manufacturing efficiency while retaining the flexibility needed to respond to local contexts and community requirements.
Factory-controlled production offers levels of precision and consistency that are difficult to achieve with people on site. The result is improved quality assurance, reduced waste and greater confidence in outcomes.
In an era when housing performance and resident satisfaction are increasingly important, these benefits should not be underestimated.
3. Timber delivers better whole-life value
Procurement decisions are often driven by initial capital cost, but for organisations that will own and manage housing assets over decades, whole-life performance is a far more meaningful measure of value.
The EHD programme assessed both capital and operational considerations, including construction costs, energy use, maintenance requirements and lifecycle impacts.
The analysis indicated that the collaborative delivery model developed through the programme has the potential to generate whole-life savings of between 2% and 12%, depending on the specific details of the projects that utilise the model.
More important, the approach sought to create homes capable of maintaining performance and value throughout their operational life.
4. Timber supports high-performance affordable housing
Affordable housing should remain affordable after residents move in.
The EHD assessed energy demand, thermal efficiency, airtightness and operational carbon outcomes in occupied homes. The dwellings were designed to meet Gold-level sustainability performance under Scottish Building Standards and achieve exceptionally low energy demand through high-performance building fabric and integrated energy systems.
The buildings are now being monitored for their performance relative to occupant behaviours, with the findings due out next year.
This matters because operational costs affect household affordability. Homes that require less energy to heat can reduce fuel bills, improve comfort and contribute to healthier living conditions.
For housing providers, improved operational performance enhances resilience against future energy price volatility while supporting wider sustainability targets.
5. Timber strengthens supply chains and encourages investment
Successful housing delivery depends as much on supply chain confidence as it does on design and construction.
One of the most innovative aspects of the EHD was its focus on aggregating housing demand across multiple authorities. By creating greater certainty around future workloads, the programme encouraged collaboration between clients, manufacturers and delivery partners while providing the confidence needed for investment in skills, facilities and production capacity.
As the UK seeks to strengthen domestic manufacturing capability and increase the use of modern methods of construction, this type of collaborative approach offers a valuable blueprint.
6. Timber solves multiple challenges simultaneously
Perhaps timber’s greatest strength is its ability to address several industry priorities at once.
Carbon reduction remains an important benefit, but it is no longer the only story. The EHD programme demonstrated how timber-based modern methods of construction can support accelerated delivery, improved quality, enhanced energy performance, greater manufacturing efficiency, reduced waste and stronger supply chain collaboration.
For developers and local authorities tasked with delivering more homes under growing financial, environmental and social pressures, timber offers something increasingly rare: a solution that helps tackle multiple challenges through a single integrated approach.
The EHD research is now being embedded within the NMITE BSc Construction Management programme as a live case study, enabling students to engage directly with contemporary challenges in industrialised construction, housing procurement and low-carbon building delivery.
The lessons are also informing the development of educational resources for the Timber in Construction Skills project, a CITB-funded initiative led by Donaldson Timber Systems and its partners, including NMITE, to strengthen timber knowledge and capability across the construction workforce.
