Duration & Completion: 48 weeks -Completed 2017

A completed property next door to a property not included in the scheme


Westdale were awarded the contract to regenerate 52 non-traditionally constructed properties in the Y Fali area of Anglesey. Fuel poverty runs very high here, due to the remote nature, the thermally inefficient construction methods, and high household heating needs in this extremely exposed location.

Client Requirements:

IoACC wanted a cost effective solution for externally refurbishing the properties and one which would:

  • Be resilient to a severely exposed location
  • Improve thermal performance and therefore cut fuel bills & C02 emissions.
  • Solve the structural problems associated with this archetype

Scope of Works: The Tan Y Bryn project saw Westdale delivering an ever-increasing range of deliverables, including roofing, fenestration, EWI, soffits, fascias, rainwater goods, fencing, boundary walls, footpaths, soft and hard landscaping. This project also included total internal refurbishment works (back to bare brick); stud walling, floors boilers, gas central heating systems, electrical rewires, Kitchens, Bathrooms, and full redecoration, serving to further demonstrate Westdale’s market position as Principal Contractor.

Project Design: Westdale performed the duty holder role of ‘Principal Contractor’ under the CDM regulations 2015, managing the delivery of a number of supply chains and sub-contractors. 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.)

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 IoACC’s vision for the estate. This iterative process provided a comprehensive refinement of the final design solution: As licensed Artbrick installers, we incorporated a number of brick render details to window sills and quoins – injecting some architectural merit to these rather bland-looking properties.

Project Challenges: The scope of the programme was extended to include additional ‘Buyback’ properties – including complete internal refurbishment works (back to bare brick), which were delivered within the contract duration.

Delivery Programme: This ambitious programme was delivered within contract timescales of 48 weeks. Works were sequenced intuitively to minimise resident inconvenience. Ultimately, we developed a realistic programme (which, upon reflection, was within 5% tolerance) – allowing us to exceed our client’s expectations of contract duration. Our experience and strong onsite management presence resulted in fewer ‘unforeseens’, and through early coordination, we ensured that the project was not forestalled for need of a key decision. Westdale’s experience of managing in-house resources and local supply chains alike, meant that our delivery timeframe was a fraction of our competitors’. This speed of delivery had a positive effect upon minimising resident inconvenience – many of whom were either elderly or infirm.

Local Supply Chains: As appointed contractors to a growing number of national procurement frameworks, we acknowledge that every pound invested makes a positive contribution throughout the supply chain. In accordance with the provisions of the WAG toolkit, Westdale reported that over 70% of the contract value was delivered using local supply chains, merchants and SMES, thereby maximising local spend.
