Santa Monica homeowners are all about lifestyle—but the design world doesn’t sit still. Whether you're adding a primary suite, expanding a kitchen, or building up for views, 2025 brings new rules for luxury expansions.

Here’s what’s hot—and what’s heading out.

✅ IN: Seamless Indoor-Outdoor Flow

❌ OUT: Closed-off patios and tiny sliders

Santa Monica’s climate demands connectivity. We’re seeing:

  • Full-height pocket doors and stacking sliders

  • Covered patios with heaters and lighting

  • Same-flooring transitions for continuity

Pro tip: Design your addition around natural light and air, not just square footage.

✅ IN: Wellness Rooms + Flexible Spaces

❌ OUT: Single-purpose gyms or offices

Homeowners want spaces that adapt with them. Trending now:

  • Meditation lounges that double as work zones

  • Home spas with saunas + cold plunges

  • Murphy beds for multifunctional guest spaces

Design for wellness—without wasted space.

✅ IN: Low-Carbon Luxury Materials

❌ OUT: Overbuilt marble and exotic hardwoods

2025 is about eco-conscious beauty. Try:

  • Terrazzo with recycled content

  • FSC-certified wood accents

  • Plaster + limewash over standard paint

Green doesn’t mean granola—it means grounded, thoughtful elegance.

✅ IN: Raised Ceilings + Light Wells

❌ OUT: Drop ceilings and dense overhead lighting

Additions are becoming light-driven, not boxy. We’re building:

  • Skylights and clerestory windows

  • Vaulted ceilings with exposed beams

  • Solar tubes in hallways and baths

Let Santa Monica’s sun do the heavy lifting.

✅ IN: Smart Shading + Climate Control

❌ OUT: Over-reliance on AC

The best additions cool themselves with:

  • Auto-adjusting shades tied to sun exposure

  • Window orientation for passive cooling

  • Green roofs and reflective finishes

Luxury means comfort without overconsumption.
