in the US there is an organization called habitat for humanity. i don't know if there is a similar organization over there or not, but if so they are always looking for volunteers, and it is closer to the field you are studying for. they build homes for the poor who would otherwise never have the opportunity to own their own home. land and materials are all purchased, and the rest of the process is done by volunteers. the new homeowner is required to put in x amount of "sweat equity" in building the home, and others in the community volunteer to do everything from the actual engineering/architecture to the building itself. i would look into it and see if there is such an organization where you are.
