The special green house is set to become the most energy-efficient home in Britain, and will leave them with fuel bills of just £70 a year.
Their cosy new home in Huddersfield, West Yorks., will be finished in February next year and will be the first Anglicised version of the famous German Passivhaus.
Instead of complicated design and expensive bolt-on renewables like wind turbines and ground source heat pumps, Passivhaus creates a simple "tea cosy" effect.
It relies on simple design, orientation towards the sun, careful construction and insulation 15 times greater than required by Government building regulations. This ensures almost complete air and wind tightness.
No draughts can get in the building and no heat can leak out, but the air is never stale, thanks to a mechanical heat recovery ventilation system that brings in fresh air from outside, which is warmed used 99 per cent of the heat from the outgoing air.
The Green Building Store in Huddersfield suggested the unique design and is managing the build that uses a German computer software package to measure air tightness and energy efficiency.

Central Heating Day
The first of October is "central heating day", when many people switch on their radiators for the winter. Central heating is just another mod-con of contemporary living, but it's done much more than warm us up.
Up and down the country, radiators clank their way back to life after a summer of hibernation.

With energy bills soaring in recent years, and more people aware of energy consumption, many make it a point of principle that their heating stays off until the start of October, which means any nippy late September mornings just have to be endured.
But given how mild the autumn has been so far, others may wait a couple more weeks before the big switch-on.
Only a small fraction of UK homes are without central heating today. In the last comprehensive survey, in 2004, it was 7% of households, and that has probably dropped further since.
Far from being a modern invention, there were forms of central heating systems in ancient Greece, and later the Romans perfected what were called hypocausts to heat public baths and private houses.
In late Victorian Britain, well-to-do houses had a form of central heating. Cragside in Northumberland, the family home of engineer Lord Armstrong, was a famous example, with ducts built into the floors to carry warm air around the building.
But it was a long time before central heating became widespread and affordable, and fired by a gas boiler.
Luxury!
In 1970, Martyn Jarvis, 55, was a gas fitter, installing central heating systems in the Slough area.

"Central heating was just taking off then and there was a sense of excitement. It was like getting the first colour television - 'Ooooh, I've got central heating!'
"Unless you were really well off, you didn't have any radiators. There was an awful lot of solid fuel around then, an open fire in the living room normally, which heated the water as well.
"Other houses just had a three-bar electric fire, so you needed plenty of blankets at night. I remember the 1963 winter was particularly horrendous."
By the end of that decade, and into the early 1980s, having central heating was regarded as a basic requirement, he says.
PLUMBING IN THE 1970S
I started in 1974 and central heating was just taking off. It was quite expensive then because it was a big job.
We had to take out a lot of old-style coal fires with a back boiler to heat the hot water and an open grate at the front. But people loved it, after being cold for all those years

There were obvious health benefits - warmer homes helped to address winter mortality rates - but the impact was wider than that.
The design of a home changed because its inhabitants started behaving differently, says architect Harry Charrington. Today the average temperature in a home is 22C, compared with 18C in the 1950s, he says, yet people 50 years ago felt just as warm as we do today.
"People don't wear clothing to keep warm any more. One of the social norms is that people can go around in shirt sleeves at home or in the office. So central heating has changed the way people think about clothing.
"Rather than put extra clothes on, they put the heating on. It used to be that if it got cold, you put a jersey on and if it got warm you opened a window. People don't have an expectation that they will have to change the way they behave in cold weather."

Fridge Scrappage Scheme
It is an idea which has revitalised the motor industry.
Now retailers are copying the cash-for-bangers scheme by offering financial incentives to replace your old fridge, freezer or washing machine.
Up to £200 will be available for used appliances and white goods.
Comet has signed a deal with manufacturer BSH Home Appliances to offer a 20 per cent price cut on leading brands such as Bosch, Siemens and Neff.
The move follows calls from the British Retail Consortium for the Government to offer a white goods scrappage scheme to encourage a switch to energy-efficient devices.
In August, Sony launched its own scheme for TVs.
Retailers and manufacturers also want VAT to be removed from new appliances to encourage consumers to switch to greener models.
The Comet scheme would seek to emulate the car scrappage scheme, which has encouraged motorists to buy fuel-efficient cars.
It would also include free collection and recycling of the old appliances. The 20 per cent discount will be offered on any one of 340 appliances from Bosch, Siemens or Neff.
Deals include a scrappage saving of £74.80 on a Bosch WAA24270GB washing machine, bringing the price down to £299.20.
A Siemens SN26M290GB dishwasher will be reduced from £619.90 to £495.90, a saving of £124.

Boiler Scrappage Scheme
The idea is to persuade the government to work with boiler manufacturers to create a scrappage scheme similar to the recently introduced car scrappage scheme, but this time for old central heating boilers.
