Heritage restoration & conservation — NSW

Bonusrisehub specialises in sensitive restoration of plaster, cornices, mouldings and period finishes across homes and heritage buildings in Australia. We combine archival techniques with compliant modern methods.

Restored cornice detail

Why heritage restoration matters

Preserving original fabric retains cultural value and long-term asset worth. We assess significance, stabilise finishes, and apply reversable conservation-compatible materials where possible.

  • Material-first assessments
  • Conservation plans aligned with local council guidance
  • Skilled trades in lime, gypsum and traditional plasterwork

Assessment & reporting

Detailed condition reports, recommended treatments, and costs tailored for heritage grant submissions or private projects.

Conservation works

Gentle cleaning, consolidation, patching with matching mortars, and careful redecoration using traditional paints and finishes.

Project handover & maintenance

Maintenance schedules and documentation to help councils and owners keep restored elements in optimal condition.

Materials & techniques

We use breathable lime mixes for historic masonry, matching colour, texture and compressive behaviour to originals.

Traditional gypsum methods for cornices and ceiling roses, with hand-moulded and cast replacements as required.

We specify heritage-appropriate coatings — mineral paints, distempers, and low-VOC modern equivalents when required for compatibility.
