"The received wisdom that ivy destroys buildings has been overturned by a new study by Oxford University.
In a three-year project, Oxford researchers analysed the effects of ivy growing on buildings in five different parts of England and discovered that the plant plays a protective role. They found that an ivy canopy was like a thermal shield, combating the extremes of temperature which often cause walls to crack.
English Heritage commissioned Professor Heather Viles of Oxford University's School of Geography and the Environment to analyse the effect of common ivy (Hedera helix) to guide them in their important role as the steward of hundreds of historical sites. Professor Viles’s research team monitored the effect of ivy on walls situated in different parts of the country with varying climates and challenges.They found that ivy acted as a thermal blanket, warming up walls by an average of 15 per cent in cold weather and cooling the surface temperature of the wall in hot weather by an average of 36 per cent. The ivy was also found to absorb some of the harmful pollutants in the atmosphere. Walls where ivy was growing were less prone to the damaging effects of freezing temperatures, temperature fluctuations, pollution and salts than exposed walls without ivy.
Professor Viles said: ‘Ivy has been accused of destroying everything in its path and threatening some of our best loved heritage sites. Yet these findings suggest that there are many benefits to having ivy growing on the wall. It not only provides colourful foliage but also provides walls with weather-proofing and protection from the effects of pollution.’

You post some good links on here, when it comes to alternative living structures.
The shipping containers/ woodland homes/ hobbit houses.
To my eyes, these are all vastly superior living spaces, to conventional housing, and cost a relative pittance to build.
PS: you live in a 2 up 2 down i'm guessing:-)
