MERCER ISLAND, WA — Known for its luxury homes, lakefront views, and peaceful landscapes, Mercer Island is where outdoor living is more than a lifestyle—it’s an art. Homeowners here are investing in custom decks that elevate both property value and personal enjoyment.
At King County Decks, we’ve helped countless families across Mercer Island, Bellevue, Seattle, and Redmond design decks that match the sophistication of their homes. Whether it’s a three-story showpiece with a jacuzzi or a simple space for outdoor dinners, these are the top trends shaping decks in 2025.
1. Multi-Level Decks with Defined Living Zones
Mercer Island homeowners are embracing multi-level designs to separate spaces for cooking, lounging, dining, and spa use. Raised platforms for hot tubs or sunbathing areas, with transitional stairs and custom railing, create both function and visual appeal—especially on sloped or terraced lots.
2. Low-Maintenance Composite Decking
While natural wood has its charm, many residents are switching to composite decking for its sleek look and hassle-free upkeep. With weather-resistant textures and fade-proof colors, composites are a smart choice for lakeside properties. At King County Decks, we offer a wide selection of both affordable and luxury materials to suit every taste.
3. Modern Railing Systems
Outdated balusters are being replaced with contemporary railing systems made from aluminum, glass, or cable. Homeowners across Kirkland and Mercer Island are choosing styles that preserve views while offering top-tier safety and wind protection. Frameless glass railing, in particular, is ideal for waterfront decks overlooking Lake Washington.
4. Covered Spaces with Pergolas and Roof Extensions
To extend the usability of outdoor spaces, pergolas, retractable awnings, and fully covered roof extensions are becoming must-haves. These additions offer shelter from sun and rain while adding elegance and structure. Whether in Tacoma or Redmond, we design every cover to match your home’s architecture.
5. Built-In Lighting for Nighttime Ambiance
LED lighting integrated into stairs, railing, and under-deck trims is now a standard for high-end deck builds. Soft, ambient lighting not only enhances safety but transforms the entire space after sunset—perfect for evening dinners or cocktail hours with guests.
6. Outdoor Kitchens and Entertainment Hubs
Custom decks are evolving into full outdoor living rooms, complete with BBQ stations, pizza ovens, bars, and media setups. These features are particularly popular on Mercer Island, where social gatherings often spill into the backyard.
7. Spa Integration and Wellness Spaces
More homeowners are choosing to integrate jacuzzis, plunge pools, or yoga decks into their custom designs. This adds a wellness retreat right outside your door. We handle all necessary framing, waterproofing, and utility access to make these features seamless and secure.
