Every projekt is different. It is our daily life to meet and help building project on the ecological and sustainable

We know how extreme complex it is to make ecological  concept for a house - from placing to the four corners of the earth and conditions of the plot, the room mutual placing to zoning of the house, choice of construction to materials, insulation, diffusion, windtightness, the placement of installations, future changes (flexibility), choice of heating system, sanitation and so on and so on.
