This is a £5.5 million project…. We have already secured £2.75 million of in-kind support from Berkeley Homes.

To succeed with the establishment of Trent Park Museum, we are relying on financial donations. This is your museum – and a vital part of our national heritage, now recognised as being on a par with Bletchley Park. Your donation is important. Please donate to the Trust from £1 upwards!

Your generous support will preserve this iconic and supremely significant part of our nation’s history

If you are a corporate sponsor or interested trust, who would like to be honoured in perpetuity on our prestigious Museum Founders Board by making a substantial donation towards our capital fit-out costs, please contact us to discuss. Or maybe you can sponsor one room, or donate in memory of a member of your family who worked for MI9 / MI19.

Online appeals via social media have made a difference, but we need the donations to keep coming in!

Trent Park is the last and only national site where the secret listeners of WWII can now be told.

The Trust has successfully completed fundraised £50,000 in 6 months! This was to complete the first stage of work. Your donations and private sponsors have enabled the following necessary work to be completed:

  • Developing the initial Business Plan – to assess the viability of the museum, and identify the income streams required for sustainability; as required in the Memorandum signed between the trust and Berkeley Homes. The viable Business Plan has been produced  by Barker Langham, through generous funding from Berkeley Homes and in-house support.
  • Devising the Content Brief – to select and develop the most appropriate stories to be told (in exhibition and interpretation), identifying the objects that will enhance these stories (via collections and loans), and the activities that will bring the stories to life (e.g. tours, talks and education projects)
  • Engaging a firm of historic architects to undertake initial historic surveys of the mansion house to liaise with Berkeley Homes during asbestos removal and renovation phases
  • Creating a Concept Design – to translate the Content Brief into a museum plan, using the given space most efficiently and imaginatively and capturing the essence of the house’s former life, as well as providing key information on which to shape the scope of the necessary capital works.

Berkeley Homes is restoring and renovating the fabric of the stately rooms according to its Grade II listed status and the basement for the museum. This work, estimated at £2.75 million, has now begun. Exciting times and a real commitment by Berkeley Homes to help the Trust realise the vision.

In the autumn, we will enter the next major milestone in the museum’s development – for the appointment of a Quantity Surveyor and Engineer; and to raise £100,000 to take the build project to end of March 2019.
