This study is interested in ongoing trends – ecological building – our future of living. Offers appreciation to modern civilization in relationship with architecture, its forms and also with nature. Contemporary trends and near future in architecture. Further I describe ecologically suitable materials and their use in Europe and in the World. In short i describe some ecological objects in Slovakia. Ecology and sustainable development is still more considered as our future possibility. I try to explain a term „Ecostructure“, witch can name the whole problem.
