£5.5m price tag for architect's Shropshire mansion

Hammer Hill House in Romsley, near Bridgnorth, was designed by Sir Bertram Clough Williams-Ellis, the architect responsible for designing and building the village of Portmeirion in North Wales.

Portmeirion was built between 1925 and 1975 in the style of an Italian village and is now owned by a charitable trust.

It has served as the location for numerous films and television shows, the most notably the 1960s show The Prisoner which starred Patrick McGoohan.

Sir Bertram designed Hammer Hill in 1923, not too long before he embarked on the project in Wales for a cousin of former Prime Minister Neville Chamberlain.

It has since been greatly extended, with the house now spreading more than 14,000 sq ft and boasting its own indoor swimming pool, dance floor and lift.

The six-bedroomed country house stands in 28 acres of Shropshire countryside in an elevated position above the Severn Valley in Romsley Lane in the small rural hamlet of Romsley.

It commands spectacular views to The Clee and Welsh Hills and stands in beautiful landscaped gardens.

A spokesman for agents Andrew Grant said: "It has been fitted to an exceptionally high specification throughout to include a magnificent drawing room with a sprung and lit dance floor, panelled walnut dining room with fitted serving area and an impressive hall with a sweeping walnut staircase leading to the galleried landing.

"The indoor heated swimming pool is situated, along with a hot tub and changing rooms, in a beautifully designed room easily accessed from the kitchen and opening to the garden beyond and a sheltered courtyard."

The house contains five reception rooms, a bespoke kitchen-cum-breakfast room, a master bedroom suite, five further bedrooms and an extensive garage and office compex.

The spokesman said the property came with two matching, period gate houses, each offering three bedrooms "suitable for staff or letting". Each also has front and back gardens.

The house is approached through wrought iron, electric gates opening to a sweeping tree-lined driveway to the turning circle to the front of the house and into the walled coach yard to one side.

The landscaped gardens and grounds have sweeping lawns, glasshouses, stocked borders and hidden pathways through wooded vistas.

The house has extensive grazing land with four paddocks partially surrounded by mature woodland.

Hammer Hill has outstanding planning permission for an agricultural building and erection of a detached garage.

Offers are being invited in excess of £5,500,000 and viewing is strictly by appointment via joint agents Andrew Grant, on (01905) 734735, or Savills, on (01242) 548000.

Sir Bertram, who was born in Gayton, Northamptonshire, on May 28, 1883, is often referred to as being a self-taught, natural architect and landscape designer.

He attended Trinity College, Cambridge, and went on to do only a few months in formal architectural training before opening his own architectural practice in London when he was just 22 years old.

He was a life long advocator and protector of the environment which led to him being awarded a knighthood in 1971 for his services "to architecture and the environment".

He built Portmeirion on his own private land in Snowdonia, Wales, and it rose into the spotlight of the world with the filming there of The Prisoner' in 1967.

The village is today a site for tourism and remains a masterpiece of his work.

Sir Bertram left his distinctive designs throughout the United Kingdom and further afield.
