TV celebrity Alex Proud has officially re-launched Stanmer House in Stanmer Park.

More than 300 guests, including business leaders, trade associations and councillors, were at the launch.

His fully-restored mansion features a new restaurant called Source at Stanmer.

The Grade 1 listed Proud Country House was brought into the Proud Group in 2016.

It has now been fully restored with juxtaposing antiques and reclamation yard finds, 70s glamour and modern patterns while still retaining the original charm of the 295 year-old house.

Next year a £3.75 million investment starts in the 20 hectares surrounding the house to restore the Grade 2 listed parkland and outbuildings and make the estate more accessible for cyclists, walkers and cars.

Alex Proud said, “I am delighted to be the new custodian of such an important Heritage site in Sussex – the place where I grew up.

“In fact, my mother cried when I told her I’d taken on Stanmer – the love for this building and estate runs deep .

“I hope our customers old and new enjoy the changes and improvements we’re making front of house and behind the scenes.”.

The doors were also formally opened at the new restaurant Source.

Mr Proud said: “Serving a seasonal British menu, using fresh fish, meats and produce from within a 20-mile radius, Source is simply and beautifully cooked food, served at a price that is fair for everyone from producer to guest.”

Head Chef James Mitchell brings his new ‘farm to fork’ approach to Proud Country House having previously worked for The Savoy Hotel and Hilton Park Lane,.

James said: “I believe in starting with the very finest ingredients, treating them with respect and letting the quality speak for itself.

“We have something for every palette – from light salads to beautiful on the bone rib of beef.”

Alex Proud - star of the popular Channel 4 series Four Rooms - signed a long lease on Stanmer House in 2016.

He took over after pub operator Whiting and Hammond ended its five year involvement with the venue.

The Proud Cabaret founder was born opposite the Goldstone ground in Hove, lived as a child near North Road, Brighton, and has fond childhood memories of the 18th Century manor house.

He is determined to make Stanmer House a success but he previously told The Argus it will take time and he is determined not to rush.

He said: “Brighton really is an important part of our future and I see Stanmer House as a flagship building for the Proud Group.”
