Why Garden Room Prices Vary So Much
This is where most buyers get caught.
Two garden rooms might look similar online — but the price difference usually comes down to:
- insulation thickness
- window quality (basic vs high-spec uPVC)
- roofing materials
- structural build quality
- what’s actually included
For example, many Loghouse builds include:
- insulated walls and roof as standard
- high-quality double-glazed windows
- full installation
Whereas cheaper options often don’t.
Cost Per Square Metre (Realistic Irish Range)

- Smaller units: ~€900–€1,200 per m²
- Mid-range: ~€1,200–€1,500 per m²
- High-spec eco rooms: €1,500+ per m²
This aligns with what most buyers experience once everything is included.
