Summary of the contracting process

The procurement process detailed here is initiated by The Crown Estate, a prominent central government public authority based in London, United Kingdom. The project, titled "Westwick Row - Main Contractor Design & Construction Works," falls under the construction industry category with a focus on works. Originally planned as a new-build residential project in Leverstock Green, Hemel Hempstead, the procurement stage has shown progression from planning to tender and recently faced some cancellations. Key dates include an expression of interest deadline set for 27 March 2026, with competitive stages set to commence in March and April 2026, aiming for an award by June 2026. The procurement method employed is a selective, competitive flexible procedure, with a significant total project value estimated at £29.64 million gross, providing opportunity above the threshold.

This tender represents substantial opportunities for business growth, particularly for companies specialising in sustainable construction solutions such as low-carbon builds, timber frame construction, or housing projects aligning with Passivhaus principles. Strategic engagement with The Crown Estate could unlock pathways for innovation in design and construction methodologies, enhancing supply chain capabilities and sustainability propositions. Companies with expertise in Design & Build or Management Contracting are particularly well-suited to compete. The procurement's focus on high-quality and cost-efficient proposals through a Most Advantageous Tender criterion allows businesses to showcase their holistic capabilities ranging from programme management to supply chain and risk management, covering aspects such as environmental innovation and social value commitments.
