Opportunity overview

The Conservatory Vision is a major part of the Barbican Renewal project, focused on restoring and transforming the Barbican Conservatory into an accessible, sustainable, and vibrant public space that celebrates its original Brutalist design. Key works include the full replacement of the glazing and installation of a new louvre system for improved climate control, strengthening of structural frames, new staircases and lifts for access to upper balconies, and new waterproofing and floor build-ups. The project will also deliver a reconfigured internal layout with relocated planters, ponds, and walkways; upgraded mechanical, electrical, and horticultural systems; and refurbished event spaces, foyers, and visitor facilities. Improved lighting, accessibility features, and sustainable planting will enhance both public use and private event potential. By combining sensitive conservation with sustainable design and eco-brutalist landscaping, the revitalised Conservatory will become a welcoming green sanctuary in the heart of the City - honouring its heritage while ensuring its long-term future.

Description
The City seeks input from the contractor market to understand what might be the most attractive way of packaging and scoping a future procurement opportunity to deliver the project outcomes. This Pre-Market Engagement (PME) exercise will provide an opportunity for the City to obtain insight into how contractors might approach the delivery of the project. It also gives a useful early insight into the likely level of interest in a proposed project from the market. Interested organisations will be asked to complete and return a brief questionnaire. To access the PME questionnaire and supporting documentation, please register on the electronic tendering system 'City of London Corporation Sourcing & Contracts Portal' (url:https://cityoflondon.ukp.app.jaggaer.com/esop/ogc-host/public/cityoflondon/web/login.jst?_ncp=1750328586606.1507105-1) and search for 'Barbican Renewal Conservatory'. Organisations should submit their completed questionnaire in accordance with the instructions set out in the PME documentation, by the return deadline of 12:00pm (noon / midday) on 5th December 2025. Following receipt and review of questionnaires, the project team may conduct further direct discussions with organisations of interest to further explore the themes set out in the questionnaire.
