Buildings and materials

A Passive House is not necessarily a healthy house, but they are not mutually exclusive.
This led us to develop the FeelGoodHouse concept.

With its single shell ' House' construction concept, FeelGoodHouse allows you to consciously live in a healthy environment. We build a wooden house around one of calcium silicate bricks with the advantages of both:

The calcium silicate brick:

  • Solid and strong
  • Made solely of the natural materials water, sand and lime.
  • Short shipping route (factory 50 km from Luxembourg)
  • Requires very litter water for manufacture
  • Natural heat accumulator
  • Excellent humidity regulator, which leads to a very healthy interior climate
  • Ideal protection against the heat in summer and the cold in winter
  • High fire resistance
  • Durable over time (retains its value well)
  • Excellent sound insulation
  • Breathable (open to water vapour)


  • Natural
  • Durable
  • Renewable
  • Low ecological impact
  • Breathable (open to water vapour)
  • Wood wool insulation
  • Both structures are assembled mechanically without glue
  • Materials that can be completely dismantled, separated and recycled
  • No Styropor or other petroleum-based materials in our houses.
  • Wood windows from regional forests with a sustainable forestry economy certificate
  • Lime or clay rendering
  • Decentralised dual-flow ventilation system for reasons of hygiene
