What Makes a Cottage Ecological

Ecological construction isn't a single product category — it describes a combination of material choices, energy systems, and site decisions that reduce impact across the building's lifetime.

  • Locally sourced timber from certified FSC/PEFC Polish forests reduces transport emissions significantly
  • Mineral wool and cellulose insulation both meet Polish thermal requirements for seasonal use at lower embodied carbon than EPS
  • Rainwater harvesting with a 2,000-litre buried tank covers most non-potable needs in a May–September season
  • Green roofs on flat or low-pitch sections add 20–40 years to waterproofing membrane life
  • Composting toilets eliminate the need for septic systems on plots without sewage connection
