Yr egwyddor y tu ôl i’r fenter yw darparu tai fforddiadwy, sy’n defnyddio ynni yn effeithiol trwy ddatblygu cartrefi sy’n defnyddio cymaint â phosib o goed o Gymru, prynu o gadwyni cyflenwi lleol a defnyddio paneli solar i gael gwared ar filiau gwresogi a thrydan y trigolion bron â bod. Mae’r prosiect hefyd wedi cynnig prentisiaethau gwerthfawr a chyfleoedd am waith yn lleol.
The concept behind the initiative is to provide affordable, energy efficient housing by developing homes using as much locally sourced Welsh timber as possible, purchasing from local supply chains and utilising solar panels to virtually eliminate occupants’ heating and electricity bills.  The project has also offered valuable apprenticeships and local employment opportunities.
