If you are the kind of person who for whom the mention of the words 'septic tank' make you feel like losing your lunch, then this house is not for you. Its an almost totally self-sufficient, really well built property on rustic land just outside La Pobla de Vallbona, and so less than 30 minutes from Valencia city, the airport and the beach.

Its a timber frame house set on a concrete base. Electricity is by solar panels, as is the hot water. It is connected to the water system for potable water, but there is a rainwater collection system to a 16000 litre underground tank for irrigating the garden.

2 bedrooms, incuding an en-suite, large living area, kitchen and an upper room which could be an office, another bedroom or just more living space.

And there is also a guesthouse, built to exactly the same high quality, with another 2 bedrooms, bathroom and living area with kitchen.

Both houses are heated by black solar thermal panels, and insultated to a high level. Some of the ceiling remains to be finished, but all the required material is there. Good neighbours all year round, and a large garden for vegetables and fruit trees, this house is not for everyone, but if you are looking for something sustainable yet extremely modern and comfortable, you won't do better.
