2024 SPRA Awards Winners

Best Detailing 2023 (sponsored by Protan (UK) Ltd)

Winners: Renolit Cramlington Limited and NDM Steelwork and Cladding
Project: The Gradle Quadrangles

Described by Historic England as ‘one of the very few instances where contemporary design can be considered genuinely outstanding,’ this project features curved quadrangles that snake around two listed buildings. Augmented Reality was used to detail the arrangement of the solar profiles that support the tessellated aluminium tiles, so the complex pattern could be achieved.

Health and Safety Award 2023 (sponsored by Rockwool Limited)

Winners: Invictus Roofing Ltd and Sika Limited
Project: Enthoven House

To protect the mental and physical health of residents – all ex-service and war veterans – noisy works were limited and a temporary scaffold enclosure was erected to protect the building while the existing roof was stripped. Mindful of the risk of exposure to potentially noxious gases from boiler flues, all operatives wore personal carbon monoxide alarms.

Best Refurbishment 2023 (sponsored by Building Systems UK)

Winners: IKO Plc and Certa Roofing and Cladding Ltd
Project: Cocoa Works, York

The refurbishment of this former confectionery factory – once responsible for making over a billion KitKats per year – included the installation of a 4,500m² tapered insulation scheme and single ply roofing system. This provided a lightweight, robust waterproofing solution that avoided applying excessive loads to the existing structure, while complementing the architecture of an iconic building.

Best Small Project 2023, sponsored by Elevate

Winners: Sika Limited and Contour Roofing (Essex) Limited
Project: The Butterfly Centre

Viewers of DIY SOS may be familiar with the refurbishment of this once-dilapidated caretaker’s cottage, which now serves as a hub for individuals and families with mental health challenges. With the collaboration of construction directors, contract managers, operatives and the manufacturer, the project was completed in under two days at zero cost to the community.

Sustainability Award 2023, sponsored by IKO Plc

Winners: MAC (Roofing & Contracting) Limited and IKO Plc
Project: Slough EFW Multifuel Power Plant

This plant will generate 50MW/year of electricity by processing 480,000 tonnes of waste; deliver 23 tonnes/hour of processed steam to a nearby food factory; and offset 147,000 tonnes/year of CO₂. Its single ply roofing system (including thermal insulation) was sourced from a UK-based manufacturer and specified for its coverage, minimising transport emissions and material consumption.
