Summary of the contracting process

The National Gallery appointed a landscape architect for the new wing at its Trafalgar Square site in central London. The requirement covers landscape architecture, public realm and external works supporting the Gallery’s new wing and wider estate. The appointed service spans design and delivery support across RIBA stages 1 to 7. It includes coordinating landscape and public realm inputs with the architect, engineers and specialist consultants; producing strategies, drawings, schedules, specifications and coordination information; supporting planning, listed building consent and relevant highways or public realm approvals; assisting contractor procurement; and providing construction-stage support, inspections, responses to requests for information, handover, defects and post-completion activities. This is a professional services requirement for landscape architectural services, classified under CPV 71420000.

The procurement is complete and the contract has been awarded through a selective competitive flexible procedure. The National Gallery shortlisted five suppliers after assessing a preliminary selection questionnaire, with tender interviews forming part of the process. Four final-stage bids were received. Gustafson Porter + Bowman LLP was selected on 21 July 2026 for the single lot, at £822,848 excluding VAT (£987,418 including VAT). The planned award standstill ends on 31 July 2026. The awarded contract period is from 3 August 2026 to 31 March 2032. Evaluation covered technical response, social value, resource schedule and fee schedule; supplier selection considered economic and technical criteria through the questionnaire. The original estimated value was £750,000 excluding VAT (£900,000 including VAT).

This award shows sustained demand from a major national cultural institution for landscape architecture integrated with complex public-realm and capital-project delivery. A credible competitor for comparable work would need the capability and capacity to lead landscape design across the full RIBA lifecycle, coordinate closely with architects, engineers and specialist consultants, and manage interfaces with existing conditions and a live operational estate. Experience supporting planning, listed building consent, highways or public-realm approvals and statutory authorities would be relevant, alongside the ability to develop tender information, answer technical queries and support contractor procurement. Delivery strength would also require construction-stage site attendance, inspections, review of contractor proposals, handover and defects support. The evaluation demonstrates that technical quality, social value, resource planning and fee management matter, and that an SME-sized practice can compete for this scale of requirement.
