Summary of the contracting process

The National Gallery appointed a landscape architecture practice to design and support delivery of landscape, public realm and external works for its new wing on Trafalgar Square in central London. The commission covers the project from early design through completion, including coordinating landscape proposals with the architectural design, engineers, specialist consultants and the wider project team. Work also covers the site’s existing conditions and operational constraints, and support for planning, listed building and relevant highways or public realm approvals. The landscape architect contributes to procurement and contractor queries, then provides construction-stage support, inspections and advice through handover, defects and post-completion. This is a specialist landscape architecture and public realm design service for a major gallery expansion, rather than a construction contract.

The procurement is complete and the contract was awarded to Gustafson Porter + Bowman LLP. The award was made on 21 July 2026, at £822,848 excluding VAT (£987,418 including VAT). The signed contract began on 3 August 2026 and runs to 31 August 2033; the award-stage period was stated to end on 31 March 2032. The procurement used a competitive flexible procedure with a shortlist following assessment of a preliminary selection questionnaire, and tender interviews. Four bids reached the final stage. Selection considered economic and technical criteria; tenders were evaluated on technical response, social value, resource schedule and fee schedule, with weightings to be set out in the tender invitation. The procurement was a single lot, with an estimated value of £750,000 excluding VAT (£900,000 including VAT).

For suppliers who did not win, this award demonstrates the National Gallery’s demand for a landscape architecture team able to carry a complex public-realm commission from early design through construction and post-completion. A credible competitor would need to show capacity across the full design and delivery lifecycle, including production of stage-appropriate strategies, drawings, schedules and specifications, and effective coordination with architects, engineers, specialist advisers and a live operational estate. Experience supporting planning, listed-building and relevant highways approvals, contractor procurement and tender clarifications, site inspections, requests for information, handover and defects would be directly relevant. The evaluation also signals the importance of a strong technical submission, social value, a convincing resource schedule and a competitive fee. Four final-stage bids, all from SMEs, show that specialist smaller practices competed for this substantial, long-duration appointment.
