Southleigh Park House, in Havant,Â is being sold by Hamptons International and Lambert Smith Hampton (LSH), with outline planning permission in place for 70 homes within its 7.8-acre grounds.
Detailed planning consent has also been secured for conversion of the original Grade II-listed house into nine apartments, and for 11 mews house conversions in the estate's stables, west wing and coach house, which are also listed.
David Atkinson, associate director at Hamptons International, said: '˜We believe an imaginative, stand-alone residential scheme can be delivered in this picturesque setting, for which there will be very little genuine competition in terms of position and setting.
'˜This is an exciting opportunity to create a safe and secure residential enclave with the benefit of shared, high-quality landscaped areas and a mix of sizes and styles of accommodation to suit a broad range of purchasers.'
Southleigh Park '“Â the name of the manor house and estate '“Â isÂ near to Rowlands Castle, Emsworth, and the South Downs National Park.
ItÂ was established in the 1850s as a Victorian gentleman's estate. Its current owners include an architect whose knowledge of period properties has underpinned a substantial restoration of the listed buildings currently in use as offices.
ResidentsÂ will benefit from a traditional parkland setting with lawns, mature trees, andÂ views towards the coast at Langstone Harbour.Â
Some objections to the plans have been lodged via the Havant Borough Council website. Mr and MrsÂ Tessem-CottonÂ cited concerns about an increase in traffic alongÂ Eastleigh Road, where they live, stating it was never designed to be a through road, or used for heavy traffic.
They also added children will need to use the road to get to nearby schools and in their letter of objection, added: '˜Unless a footpath is provided, or the road is capped with cycle or walking access only, lives will be lost.'
Graham Holland, of LSH, said: '˜Due to the excellent condition of the buildings and grounds, and the fact that planning permission has been secured, we are expecting considerable interest in Southleigh Park.'
