If you want your Groovy Garden Room to be fully self-sufficient and not have to rely on being conected to your home's mains supplies of electricity, water, broadband and waste, then this is for you.
The following are just some of the very useful and life enhancing environmentally friendly (hence Groovy Green!) items that help you achieve healthy self-sufficiency (prices include labour & parts)...
Photovoltaic roof tiles blend into a roof's design more than solar panels as they're designed to blend in more and look like normal tiles. But the costs, as a result, tend to be twice what solar panels are...and start from about £625 per m². There are also other related costs with solar energy, namely a solar charge controller, an inverter, a deep cycle battery and a battery monitor which, individually, range in cost from about £200 - £500.
These can be installed on a roof or as a separate stand alone unit alongside your garden room. Costs start from about £325 per m². There are also other related costs with solar energy, namely a solar charge controller, an inverter, a deep cycle battery and a battery monitor which, individually, range in cost from about £200 - £500.
A small wind turbine gives you added power (even more so if you also use solar energy to power your garden room). Small quality wind turbines cost from about £500 and an inverter to convert the power from around £175.
These are waterless, electric incinerating toilets that have a simple, one-button operation that leaves only ash as a residual product. They have the capability of handling the toilet needs of up to 6 people on a regular basis. They keep track of the number of visits and adapt the incineration time to ensure that the waste product is always ash. Costs start from about £2,750.
These toilets are waterless and are designed so your waste (they come with a urine separator) can then be used for compost. They need to be connected to electricity for the extractor fan to remove any odours. Prices start from about £395.
Satellite broadband is transmitted using a wireless connection via a satellite dish, similar to those you use for satellite TV. To use it, you need a satellite dish and a transmitter attached to or by your garden room with a clear line of sight. This connects wirelessly to a geostationary Earth-orbiting satellite that receives and sends a broadband signal to your home. Set-up costs start from about £600. And monthly service rental starts from about £25.
