Estate agent Bill Humphries from W Humphries Estate Agents in Waddesdon told MailOnline: 'By virtue of the fact it's on the estate you could safely say it's worth £2million plus'

The house, designed by architects Skene Catling De La Pena, sits in the grounds of Rothchild’s estate at Waddesdon Manor and has been constructed using masonry and flint cladding

Riba commented that the home is ‘an intriguing and intelligent mixed application of rooftops, terraces and recesses that combine to deliver a stunning piece of liveable, provoking, modern architecture that marries into the earthly yet beautiful countryside’

Judges said that Flint House was a 'beautiful addition to a beautiful landscape'

Flint House is one of the most unusual abodes in the British Isles - described as 'superbly original and unique'

Flint House, the judges said, 'continues a fine tradition of Riba award-winning houses that provide exemplars for others: architects, clients and developers'

The house is built on a seam of flint geology and is surrounded by ploughed fields where the flint sits on the surface

It was described by judges as ‘a marvel of geological evolution and construction… a celebration of location, material and architectural design at its best’.

Riba commented that the home - which is split into a main house plus an annexe - is ‘an intriguing and intelligent mixed application of rooftops, terraces and recesses that combine to deliver a stunning piece of liveable, provoking, modern architecture that marries into the earthly yet beautiful countryside’.

The judges added: ‘This is a beautiful addition to a beautiful landscape.’

The house was revealed as the winner by Kevin McCloud on Grand Designs: House Of The Year on Channel 4.

Riba President Jane Duncan said: 'The shortlist for the Riba’s House of the Year represents a remarkable diversity of architectural skills and outcomes.

‘I am delighted that Skene Catling De La Pena’s Flint House for Lord Rothschild has won this year’s prize. Although superbly original and unique, it continues a fine tradition of Riba award-winning houses that provide exemplars for others: architects, clients and developers. Congratulations to all involved.'

The best of the rest: From a renovated mill in Scotland to a stunning country retreat in Sussex these are the House Of The Year runners-up

The competition for the House Of The Year Awards was stiff, with several remarkable homes vying for the top honours.

They ranged from a cleverly designed urban mews house to an expansive country retreat.

Runners-up in the awards were Kew House in London by Piercy&Company, Levring House in London by Jamie Fobert Architects, House at Maghera in County Down by Mcgonigle McGrath, The Mill in the Scottish Borders by WT Architecture, Sussex House in West Sussex by Wilkinson King Architects and Vaulted House, London, by vPPR Architects.

Kew House - a four-bedroom family house - was praised by Riba judges for being 'rich with incidental spaces and unexpected light sources'.

Kew House - a four-bedroom family house - was praised by Riba judges for being 'rich with incidental spaces and unexpected light sources'

Kew House, completed in January 2014, won accolades for being sympathetic to the lifestyle of a young family

The home, completed in January 2014, is split into two wings and 'responds to the living patterns of the young family'.

Levring House, which fills a corner plot of a London mews, was described by the judges has having a 'heady mix of free-flowing space, light-filled voids... and a brilliant regard for the surrounding context'.

The house is constructed using Danish hand-made bricks, bronze panels and glazing. Inside there is a 'glorious' double height kitchen and dining space, hidden terrace, master bedroom and sunken basement.

Riba said: 'This is architecture of sophistication and delight, crafted out of a tight and complex urban site with skill and panache.'

Vaulted House in London was another house that impressed the Riba judges and was short-listed for House Of The Year

Vaulted House is arranged so that on entry, visitors are poised between two levels, with stairs leading up to the open-plan living level, and down to the lower level of bedrooms

Vaulted House, in London, is built on the walled site of a former taxi garage and is almost entirely hidden in the middle of a Victorian block in Chiswick.

The approach is via a covered passage, beyond which is a brick-lined front porch.

The house is arranged so that on entry, visitors are poised between two levels, with stairs leading up to the open-plan living level, and down to the lower level of bedrooms. The six roofs, each topped by a skylight, are lifted above the enclosing boundary wall.

Sussex House, meanwhile, is a stand-alone contemporary villa set in the countryside.

Riba described it as 'an exceptional retreat' with a 'quietly confident exterior'.

It added: 'A lack of decoration and ornament gives this modern house a functional feel, but one that is cleverly considered to the very last detail.'

House at Maghera in County Down wowed the Riba judges with its 'exemplary and demanding detailing'

The judges said: 'This is a family house providing an empathetic framework of beautiful spaces for its occupants'

The house in County Down was deemed to be a 'credit to architect, client and builder'

House at Maghera has a distinctly minimalist interior - and one that wowed the judging panel

House at Maghera, meanwhile, is on the edge of a clachan - a small grouping of farmsteads - on the leeward side of the stunning Mourne Mountains in County Down.

The entrance hall leads to a music room that's enclosed by a pair of folding and sliding barn doors.

A guest bedroom to the east occupies the end gable of a shorter building.

The judges said: 'This is a family house providing an empathetic framework of beautiful spaces for its occupants, opportunistically using the site and appropriate technologies to achieve an eminently habitable and sustainable home. The quality of construction is very high, exemplary and demanding detailing executed with evident local skill and obvious pride - who said craft was dead? It's a credit to architect, client and builder.'

The Mill, in the Scottish Borders, by WT Architecture, is a distinctive conversion of an old mill, as the name suggests

The main living space at The Mill is half a level up from the dining-hall, with a new window overlooking the valley below

With runner-up The Mill, the brief given to WT Architecture was to convert the mill into a modern, rural holiday home that retained much of its historic character.

The front door, which was reused, opens to a boot room lined in larch. This opens on to a dining-hall with glimpses into the main living spaces beyond.

Steps lead down a half level to the kitchen, which opens out to a wild garden.
