The work covers the project from RIBA Stages 1 to 4, spanning preparation and briefing through concept design, spatial coordination and technical design support. The requirement sits within architectural, engineering and planning services, with planning consultancy as the specific focus. It was intended to support development pipeline planning for the Mayne House site rather than construction delivery itself. The council is the buying organisation and the services are to be delivered in London. The opportunity was identified as suitable for small and medium-sized enterprises, making it relevant to planning consultancies with the capability to advise on development proposals through the early and developed design stages. This procurement is complete and has been awarded. Westminster City Council used a selective call-off from the Notting Hill Genesis Development Consultants Framework, Lot 4 for planning consultants. The tender submission deadline was 6 June 2025 at 12:00 BST, and the contract was awarded on 15 October 2025. Nathaniel Lichfield & Partners Limited was selected for £174,000 including the stated currency of GBP. The contract period runs from 10 August 2025 to 24 February 2029. The recorded tender value was also £174,000. The award is active, and the requirement was evaluated through the framework call-off process rather than an open tender. This is an awarded opportunity, not a current invitation to submit proposals. For a planning consultancy that did not win this contract, the procurement provides a clear example of the capability Westminster City Council has bought for the Mayne House development site. A credible future competitor would need experience advising on development opportunities across RIBA Stages 1 to 4, with the ability to connect planning strategy to briefing, concept development, spatial coordination and technical design. Relevant firms should also understand how to work within a development consultants framework and secure call-off opportunities through its planning consultant route. The successful supplier was an SME, indicating that a specialist practice can be well placed where it can demonstrate the required technical expertise, dependable project capacity and experience supporting a development pipeline through multiple design stages. ## Notice This contract is for planning consultants for RIBA 1-4 for the Mayne House development opportunity site.
