The flagship scheme – Wilton Park – will feature up to 350 homes, as well as commercial and community developments in a parkland setting.

The plans also include the completion of the Beaconsfield relief road, which will divert traffic away from old Beaconsfield between the M40 and Amersham.

Paul Brett, group land director at Inland Homes, said: “The submission of this planning application is a major milestone in the development of one of the UK’s most unique and special sites, which has been described by Savills as ‘one of the finest development opportunities in southern England’.

•   Peel partners with Persimmon for residential development
•   Planning application put in for £5.2m council house scheme
•   OakNorth lends Hayfield Homes £9m

“The land already has an allocation for development in the south Bucks local plan and this planning application is the culmination of a number of years of hard work by the Inland team to carefully balance the aspirations of the planning authority and the local community against the need to maximise the commercial value of this prime asset, which has an estimated GDV of approximately £350m.”

Inland has constructed the first phase of the relief road, as well as significant landscaping and tree planting.

It has also made residential and commercial lettings on the site which contribute to an annualised gross income of £1.5m.
