Digital Meets Deconstruction : Maconda and Reusefully Unite to Drive Circular Construction in London

Simon Guy • 26 March 2025

Maconda and Reusefully, two innovators in circular construction, are teaming up to tackle the industry’s greatest challenge – how to turn London’s buildings into digital material banks. 

To solve the problem of construction industry waste, the two organisations are mapping their data gathering and analysis capabilities using the ROMULUS digital platform. Data from Reusefully audits will be added to the platform, via a seamless automatic upload function, to provide end clients with a powerful digital material inventory of a building asset, that which can lead to the creation of future material passports. 


The data will be gathered by Reusefully at a level of granularity that will meet the evolving requirements of the City of London, London Borough of Tower Hamlets and other planning authorities.


ROMULUS is an initiative designed to create public-private partnerships to stimulate a circular economy market in the capital. Partnering with the City of London Corporation, the London Borough of Tower Hamlets and the GLA, this groundbreaking initiative is set to establish best practice and provide evidence for targeted policy interventions. 


A community of key industry stakeholders including Nuveen Real Estate, Landsec, Multiplex, Saint Gobain and Clarion Housing Group are anchoring the initiative to drive the increased use of reclaimed materials and trace material flows using a common data template in the form of material passports.

ROMULUS is unique in engaging a collaborative platform with dynamic real-life insights, offering users access to:

  • An exclusive community for resource reuse that will use shared audit data and material passports to achieve an unparalleled level of building transparency 
  • First-hand engagement with live developments, including access to collaborative stakeholder meetings to share and learn from circular best practice
  • Real time studies of circular economy building projects across London.

“Reusefully have long been recognised as the gold standard in building audits and it is my great pleasure to announce our partnership. As the UK pioneers in Material Passports, Maconda are excited to work with experts who wrote the book on pre-demolition and pre-deconstruction audits. Combining our expertise in digital solutions and material exchange with Reusefully’s longstanding experience in audits will further our joint vision in establishing the circular economy within London’s built environment” says James Adams, Maconda Solutions.


“We provide detailed, high quality audits which, when combined with our reuse recommendations for all material types, can make a powerful difference, both for circularity and resource use, and for carbon and cost savings. We’re further enhancing the granularity of our data gathering to meet the evolving requirements of pre-deconstruction audits and improve reporting analytics. We are constantly evolving our material reuse pathways and are looking at the introduction of innovative AI technology into our audit process. Our collaboration with Maconda will help elevate and accelerate this” says Reusefully co-founder and director Gilli Hobbs.


Reusefully undertook more than sixty pre-deconstruction/pre-demolition audits in 2024, with projects ranging from large commercial spaces down to smaller residential units. These audits identified materials for reuse ranging from heavyweight structural components including steel and concrete, down to lightweight fixtures and fittings. Last year over 16,500 tonnes of embodied carbon savings were identified through reuse opportunities on Reusefully’s audits.

An Innovate UK-funded research project is aiming to create an ambitious new platform to enhance circular economy in buildings. BuildAudIt is a one year collaborative programme that will develop a proof-of-concept platform for AI-enabled ‘digital twins’ of existing buildings – enhancing the circularity potential of the existing building stock by digitising them as ‘material inventories’.
