Edinburgh Home Demonstrator
The Edinburgh Home Demonstrator (EHD) programme has delivered a new approach to briefing, design, procurement and construction to realise the ambition of the Edinburgh & South East Scotland City Region Deal housing programme.
Delivering affordable Net Zero homes through off-site offsite manufacturing
Collaboration with the City Region Deal partners, offsite manufacturers and design professionals has allowed the EHD programme to develop a suite of housing typologies that are aligned with offsite manufacturing processes. Mass customisation of homes coupled with a design-led approach to place-making ensured that the EHD business model has positively contributed to place making and the delivery of net zero ready affordable housing within the South East Region.
A customisable model that responds to place and context.
The Edinburgh Home demonstrator programme has three pilot projects being developed collaboratively with local authorities and registered social landlords from across the Edinburgh and South East of Scotland. The three pilot projects are enabling the EHD programme to test and develop the delivery model.

Granton D1 is a delivering of 75 homes using Modern Methods of Construction that will be monitored once occupied.
75 new homes utilising zero emissions heating and modern methods of construction (MMC).
Monitoring the performance of the completed homes is key to ensuring that the business model is delivering the anticipated benefits to both the developing client and the home occupier. To do so the first pilot project was monitored during its construction to evaluate the quality, speed and cost of construction, and the completed buildings are providing live data on energy performance.
All monitoring will be used to inform subsequent homes being delivered and the evolution of a new collaborative business model.
The predicted performance will be analysed and validated by Edinburgh Napier University & the University of Edinburgh based on reviews at the design stage and for a period of 12 months while the homes are occupied.
The following indicators will be included in the analysis:
Heating and appliance electricity
Internal air temperature
Carbon Dioxide (CO2) levels
Internal humidity levels
As built U-values
As built air tightness
Local weather conditions
Occupants trends
The final analysis of the build project will be available 2025.
The data will be used to understand the impact that electric heating systems have on energy demand and to refine the design of future homes constructed using the Net Zero Approach therefore, addressing the gap in performance between the designed buildings and the as built.

Delivering 140 homes using zero emissions heating and two different modern methods of construction (MMC) systems. The homes are current on site with an anticipated completion date of early 2027.
The pilot will look to:
Optimise house and flat types for MMC systems
Develop further house and flat types to be added to EHD catalogue
Test the EHD design and performance standard.
Test mass customisation of the house and flat types.
-
Delivering a pipeline of sites with multiple partners to test collaborative procurement.
Key elements to be demonstrated:
Delivery of multiple sites across multiple clients and local authority areas.
Adoption of the EHD Design & Performance Standard
Adoption of the EHD housing typologies
Adoption of an Alliance Agreement or equivalent
Collaboration around procurement and a new business model
‘Pilot 3 bundled twelve pipeline sites over five Local Authorities within the Edinburgh and South East Scotland City Region. A feasibility commission has been undertaken to de-risk projects within the pipeline, embed the regional design standards and typologies, promote collaboration, and embed value.
The resulting feasibility reports identified five sites within three local authorities that were suitable for development. The sites have now been procured appointing a single Contractor using existing framework options and are now in pre-construction phase.
Project Outputs
THe EHD programme is developing and testing a range of outputs that form the basis for the new business model. These outputs are all key to making a step change in the delivery of affordable housing to ensure that the Edinburgh and South East City Region Deal partners can deliver the volume and quality of affordable housing that is required.
Introduction to a New Delivery Model
Through collaboration with public sector partners, industry and academia, the EHD programme has developed a new model for the delivery of higher performing affordable homes.
Briefing and Design
The EHD programme will deliver a new approach to briefing, design, procurement and construction to realise the ambition of the Edinburgh & South East Scotland City Region Deal housing programme.
What’s next
A new Delivery Model for net zero ready affordable homes was successfully developed and piloted through the Edinburgh Home Demonstrator (EHD) programme.
To enable the deployment of this Delivery Model, the Edinburgh and South East Scotland City Region Deal (ESESCRD) have committed funding and resources to form the Regional Delivery Alliance (RDA).
The Regional Delivery Alliance (RDA) is one of five key priorities that is working to deliver on the City Region Deals housing ambitions through supporting delivery of the regional housing programme, transforming regional housing supply, and driving economic and inclusive growth.
-
A new model based on collaborative procurement
Will initially develop 1,000 affordable homes
