Project Case Study: Eco-Refurbishment of 55 non-traditionally constructed AIREY homes, Wrexham

Project Case Study: Eco-Refurbishment of 55 non-traditionally constructed AIREY homes (Roofing works, the application of a structural insulated render system, replacement windows & doors, plus external works (paths, fencing and boundary walls).

Client: Wrexham County Borough Council


Westdale were awarded the contract to regenerate 55 non-traditionally constructed properties at Heol is Wyn, in the Coedpoeth area of Wrexham.

Project Design: As principal contractors, Westdale performed the duty holder role of ‘Principal Contractor’ under the CDM regulations 2015, managing the delivery of a number of local supply chains. The ‘Principal Designer’ role ensured that we planned the project correctly from the outset – developing the Construction Phase Plan and completing all statutory notifications (inc. HSE F10, liaison with utilities, Planning Permissions, Building Control regulations, and the Control of Asbestos.)

Circa 90% of the contract was delivered directly by Westdale personnel; our ‘direct delivery’ model, allows Westdale to embed our company ethics, giving a tighter control on the customer journey, which results in higher customer satisfaction levels.

Scope of Works: The works consisted of the installation of Structhermtm structural external wall insulation (SEWI), replacement of pitched roof coverings including any timber repairs, eaves replacement, chimney work and associated enabling works, including external works consisting of repair & construction of concrete/tarmac paths, fencing, re-building of walls and landscaping including excavation and enabling works.

ECO Funding: Westdale provided a full turnkey service; Our in-house Energy Performance assessors and ECO funding Managers specialise in managing strong relationships with the obligated parties. Our experience allows us to gather the correct level of detailed technical information from the outset, which therefore allows us to deliver the expected lifetime carbon savings to the ECO funding partner; the risks and liabilities associated with delivering carbon savings rest with ourselves.



The recent transition to ‘Deemed Scores’ allows us to perform an assessment of anticipated ECO funding. This is followed up with post-works EPC assessment, OFGEM lodgement using Stroma software. We operate an Open-Book approach to ensure transparency. Westdale have successfully lodged carbon submissions with NPower during this transitional period– who acknowledge a number of systemic issues with ECO 2T, and we are collaborating to produce more efficient and understandable processes.)

Aesthetic Considerations: Westdale worked closely with the client, their agent, and materials specifiers. Working iteratively, our in-house architect-led design service proposed a range of different design options, taking into consideration Wrexham CBC’s vision for the estate. This iterative process provided a comprehensive final design solution.

The patented ArtBrick render technology allowed us to provide a direct match to local brick colours, sizes and textures, whilst delivering efficiencies of timescales and cost saving. This resulted in the Coedpoeth properties receiving an unrivalled aesthetic uplift – with significant increases to housing stock values.

Considerate Constructors Scheme: The Coed Poeth regeneration site was registered with Considerate Constructors as a standard item for all Westdale projects. The CCS Auditor commented: “The project has started well & it is good to see that a visit has taken place to a local school & that it has been possible to employ locally, including a trainee Assistant Site Manager from the local College. Overall, this is considered a Good site. My thanks to Steve & Sam for their time & hospitality.”  The project achieved 100% compliance and an overall received 7/10 (GOOD) for all audit themes, with a total score of 34/50.
