Interior Design Expert

Expert interior designer combining classical training with computational design tools and AI-assisted visualization.

When to Use This Skill

✅ Use for:

• Room layout optimization and furniture placement
• Lighting design calculations (IES standards)
• Color palette selection using Munsell/NCS systems
• Space planning with anthropometric considerations
• Style consultation (Mid-Century, Scandinavian, Japandi, etc.)
• AI-assisted room visualization with Stability AI/Ideogram
• Furniture proportion and scale analysis
• Circulation path planning

❌ Do NOT use for:

• Exterior/landscape design → different domain
• Architectural structural changes → requires licensed architect
• Web/UI color design → use web-design-expert
• Brand/marketing color theory → use color-theory-palette-harmony-expert
• Building codes/permits → consult local regulations
• Kitchen/bath detailed cabinetry → specialized trades
• 3D modeling implementation → use SketchUp directly

MCP Integrations

Available MCPs

Room Visualization Workflow

1. Establish room parameters (dimensions, style, colors)
2. Use mcp__stability-ai__stability-ai-generate-image for renders
3. Or use mcp__ideogram__generate_image for concept exploration
4. Iterate based on feedback

Common Anti-Patterns

Anti-Pattern: Ignoring Traffic Flow

What it looks like: Furniture blocking natural pathways, awkward circulation Why it's wrong: Rooms feel cramped, daily use becomes frustrating What to do instead: Map circulation paths first, then place furniture. Primary paths: 900-1200mm. Secondary: 600-900mm.

Anti-Pattern: Single Light Source

What it looks like: One overhead light illuminating entire room Why it's wrong: Creates harsh shadows, unflattering light, no ambiance What to do instead: Layer lighting: ambient + task + accent. See /references/lighting-design.md.

Anti-Pattern: Scale Mismatch

What it looks like: Oversized sectional in small room, tiny rug under large furniture Why it's wrong: Proportions feel "off," space reads awkwardly What to do instead: Measure room, calculate proportions. Rugs should extend under front legs of furniture at minimum.

Anti-Pattern: Paint Color from Memory

What it looks like: Selecting paint without testing in actual lighting conditions Why it's wrong: Metamerism - colors shift dramatically under different light sources What to do instead: Always test paint samples in YOUR lighting, at different times of day.

Core Knowledge Areas

Color Science (Munsell System)

Interior design uses Munsell notation: Hue Value/Chroma (e.g., 5R 5/14)

• Hue: 10 major hues in a circle (R, YR, Y, GY, G, BG, B, PB, P, RP)
• Value: Lightness 0-10 (black to white)
• Chroma: Saturation 0-max (gray to vivid)

Why Munsell for interiors: Perceptually uniform, paint companies use it, predicts color interactions.

Key concept: Metamerism - colors match under one light but differ under another. Always test in YOUR lighting.

→ See /references/color-science.md for harmony calculations, palette examples

Lighting Design (IES Standards)

Layer lighting for success:

1. Ambient (60-70%): Overall illumination - recessed, chandeliers
2. Task (2-3x ambient): Specific activities - desk lamps, under-cabinet
3. Accent (3-5x ambient): Drama - track, picture lights
4. Natural: Free daylight - control glare with shades

Key illuminance levels:

• Living general: 150-300 lux
• Reading/detail: 300-500 lux
• Kitchen counters: 300-750 lux
• Bedroom general: 50-150 lux

Color temperature by time:

• Morning: 5000-6500K (alertness)
• Midday: 4000-5000K (productivity)
• Evening: 2700-3000K (relaxation)
• Night: 2200-2700K (melatonin)

→ See /references/lighting-design.md for IES tables, CCT programming

Space Planning

Circulation minimums:

• Primary paths: 900-1200mm (main halls, living paths)
• Secondary: 600-900mm (between furniture)
• Squeeze points: 450mm minimum (not regular use)

Furniture clearances:

• Sofa to coffee table: 450-500mm
• Dining chair push-back: 900mm
• Bed side clearance: 600mm minimum

Proportion systems:

• Golden ratio (φ = 1.618): Room proportions, art placement
• Root rectangles: √2 (1:1.414) common in floor plans
• Double square (1:2): Classic rug proportions

→ See /references/space-planning.md for anthropometrics, constraint solver code

Style Reference

Major styles:

• Mid-Century Modern (1945-70): Organic curves, tapered legs, mustard/teal/walnut
• Scandinavian: Light wood, hygge, white/gray/blonde, maximize natural light
• Japandi: Wabi-sabi meets hygge, low furniture, earth tones, negative space
• Maximalist: Curated abundance, bold colors, pattern mixing
