Prince Charles and the Duchess of Cornwall today gave a 'through the keyhole' peep at their new environmentally friendly country hideaway.

Giveaways as to the identity of the owners of the Welsh property are scattered throughout the home, including the eco washing powder on the kitchen draining board and the carbon-friendly heating system.

The decor is austere - no frills with bare floors, traditional Welsh weavings on the walls and local pottery on the dresser.

Tasteful: Prince Charles and Camilla spent their first night at the Llwynywormwood estate on Monday

There is no TV or DVD player in sight in the main house - instead there are ample books on local folklore and guides to local walks across the rolling countryside.

And while there's no royal garden, the property has its own 192-acre organic farm.

Builders currently renovating the home have used sustainable products for the makeover and Camilla chose the colour scheme of duck egg blue, off whites and terracotta.

But above the fireplace is the biggest clue of all - the three feathers crest of the Prince of Wales carved into Welsh slate.

Charles and Camilla spent their first night at their new home, a £1.2million converted farmhouse on the Llwynywermod Estate near the village of Myddfai, Carmarthenshire, on Monday.

Comfortable: The royal living room, like the rest of the house, has no television

And they gave a local photographer a royal preview of the tasteful interior, including the couple's bedroom and ensuite bathroom.

Myfanwy Shorey, an interior designer based in Cardiff, said: 'This is no Footballer's Wives pad or grand palace - it is a simple, tasteful and elegant design completely in fitting with its surroudings.

'There has obviously been much regard and concern gone into the fittings - local pottery, well-designed classic Welsh furniture and homely wall-hangings.

'It is all beautifully understated but with the occasional nod to the couple's royal standing in the artwork - although I would have liked to have seen more Welsh art on the walls.

'To some eyes it may be a little austere, but it works exceptionally well in its surroundings.

The three-bedroomed house will be available to rent once renovation work has been completed early next year

'This is not Windsor nor Balmoral but a country retreat in some of the best countryside in Britain.

'Charles and Camilia have clearly stamped their own taste and trademark on their new home and they deserve to be congratulated for making every effort to get it right.'

The property will be the couple's country retreat in Wales - although they will probably spend little more than a couple of weeks there every year.

The rest of the year it will be available to rent to holidaymakers or anyone who simply wants to boast: 'I've slept in the same bed as Prince Charles.'

The three-bedromed house will be available to rent when all the renovation work is completed early next year.

'Simple and elegant' design: The dining room

Prices are yet to be announced although it is thought it could bring in between £600 and £1,000 per week.

Llwynywermod will be visited by tourism chiefs later this year who are expected to give it a five star rating.

But clients are expected to be atrracted by the same qualities that lured Charles and Camilla into buying the property - peace and quiet.

The nearest shop is a mile away along with a Chinese takeaway and a fish and chip shop.

It took Charles and Camilla three years to find the property, which they bought in March 2007.

Its previous owners, John and Patricia Hegarty, will be invited back to see the house.

Duchy of Cornwall land steward David Curtis said: 'The property when we came here consisted of just a farmhouse, a courtyard of traditional farm buildings and a number of modern buildings.

'It took last spring and summer to work out the plans and get planning consent. We started work in August and we were still here working yesterday. And there are still things left to be done.

'They (Charles and Camilla) have had a tremendous amount of input. They have been updated weekly on the progress of the property and its design.

'They got written reports and photographs and chose the colours on the walls inside and out, as well as many of the details of the furniture.'

Asked why the Prince chose this as his Welsh residence, Mr Curtis said: 'It is historic parkland, it is secluded, peaceful, has a lovely range of farm buildings, it ticked most of the boxes, basically.

'I hope that they will use it often, but it is an unknown quantity at the moment.

'Hopefully, they will use it a couple of times a year, and possibly more.

'For several years, the Prince has been looking for a property he could use as a Welsh base. It took time to find what we thought would be a suitable property.'

Locals were excited yesterday by the arrival of the Royal couple and there was speculation whether the Prince carried Camilla over the threshold of the first home they have bought together.

Pat Phillips, who lives in the nearby village, said: 'We were all surprised to learn Prince Charles had bought the estate.

'It's amazing to think that our future king lives just up the road.

'I have only seen the house from a distance but it looks fantastic and has really been brought back to life.

'I think him moving in will do wonders for the whole area.'
