Good to be green

In a bid to encourage more people to build environmentally friendly features in their homes, 18 eco-houses across Oxfordshire will be throwing open their doors in the biggest event of its kind in the country.

The houses include ex-council houses, newly built straw-bale houses and Victorian semi-detached townhouses.

George Marshall, co-ordinator of the event, which takes place on Saturday and Sunday, said he hoped more than 1,000 people would visit the properties over the weekend.

He said: "The Government is trying to get people to change the way they live but they're not providing anything inspiring, exciting or interesting.

"We think people can be really inspired by seeing things with their own eyes and talking to people who have had it done.

"There is a huge interest in this. A lot of people want to do things and want to find out what to do and wonder if it's worth it. They're also scared about the cowboys out there."

And Mr Marshall will be speaking from personal experience.

Over six months last year, he completely eco-renovated his dilapidated terraced ex-council house in Meadow Lane, Oxford, with solar panels, grey water recycling, insulation, a turf roof and recycled and eco materials - cutting energy consumption by 60 per cent.

He said: "The cost of all the eco-work we did was really not much more than the cost of doing it anyway.

"The main message we want to get across is that this is possible. A lot of people think it's too hard, but you really can do it.

"I want people who need to spend money on their homes to think about eco-renovation. It's a really smart and desirable thing, not just for hippies or hardcore greens, but something anyone can do."

Green councillors Elise Benjamin and Craig Simmons have been transforming their 1890s' home in Magdalen Road, Oxford, for the past five years.

Their semi-detached house has solar panels, advanced heating controls and a windmill - and there are plans for further renovations.

Ms Benjamin said: "There are quite a lot of people who argue that the best way to do it is new-build, but we want to show people that it's not that difficult.

"Our house is still a work in progress - we are planning to do a lot more.

"It's very important to do this. We can hang around and wait for the Government to make decisions, but everybody has to play their part - and long-term it saves bills."

Mental health charity Restore, in Manzil Way, Oxford, built a straw-bale house for its Beehive gardening and woodwork project.

Beehive co-ordinator Ainslie Aspery said: "We took a year to build it and the people who built it were all service users of the mental health service.

"Most had never done construction in their life before.

"What it generated was a fantastic feeling of achievement and it did a lot of people a lot of good.

"It was important for us to do it because it was eco-friendly and that represents a contribution to society, rather than just buying a big shed."

How much it can cost

KITTING your home out with green gadgets may help save the Earth, but it doesn't come cheap.

Solar panels, above, can cost up to £10,000, including instalment, while smaller thermal systems are cheaper at about £800.

Replacing panels with solar tubes is the cheaper option for the greener household, setting you back about £3,000.

Purchasing a biomass boiler could mean forking out £2,500 plus instalment costs for a 15-25kW unit.

An off-the-shelf single home domestic greywater system, meanwhile, will cost up to £3,000 - but there are further running and installation costs.

Sheep's wool insulation looks more of a bargain with the average price of £10 per square metre.

However, the measures will help you make savings on your energy and water bills.
