Description

The Defence Infrastructure Organisation (DIO), in partnership with the London Borough of Hounslow (LBH) and the Greater London Authority (GLA), will be launching a competition to secure a development partner for the re-development of the MOD Feltham Barracks site. The DIO, LBH and GLA have recently entered into a Collaboration Agreement that promotes joint working between the parties to enable the successful redevelopment of the Site.

Originally a War Office depot, it became known for its military intelligence facilities. The site is earmarked for closure and the DIO are working the LBH and the GLA to bring forward the site for a mixed-tenure residential development.

The site is key for two national government priorities:

1. The site is part of a programme to deliver capital receipts for the operational UK Defence budget in line with government priorities for UK security.

2. The site is part of the DIO's 'Trailblazer' portfolio intended to accelerate and maximise housing delivery in line with government priorities for housebuilding.

The DIO proposes to enter into a Development Agreement with a developer and transfer the site on satisfaction of conditions. The developer will be responsible for securing detailed planning consent; funding and delivering the scheme in accordance with a number of landowner parameters. The DIO will be responsible for providing vacant possession in accordance with an agreed programme.
