Sun Valley interior design projects in 2026 land $26,000-$115,000 turnkey at $150-$270 per square foot.
Sun Valley interior design scope and 2026 pricing
Single-room remodel — kitchen, primary bath, or significant living-room rework — runs $26,000-$68,000 turnkey across 90 days. Whole-floor refresh (kitchen, living, dining, powder) lands $68,000-$95,000 over 4-6 months. Full interior gut on a 1,600-2,200 sq ft Sun Valley home hits $95,000-$115,000+ across 6-9 months. Acoustic and air-quality upgrades scoped during interior work — laminated window replacements, attic R-value upgrade, HRV/ERV with HEPA — add $6,500-$14,000 across most scopes.Industrial-corridor interior considerations
If you're replacing windows anyway, upgrading to laminated dual-pane on industrial-corridor-facing elevations is a 15-25% premium that pays back in tenant retention and quality of life. Attic insulation upgrade is cheapest while the ceiling is open during a kitchen or living-room rework. HRV/ERV with HEPA filtration solves the open-window-or-no-fresh-air problem most Sun Valley homeowners face on hot days. We line-item all of these so you can choose.Why Sun Valley homeowners hire NPLD for interiors
