Angkorscape is a Mercer Island, WA landscape designer trusted for custom outdoor living spaces. Every project is designed in 3D and built by one dedicated team, backed by a 5-year workmanship warranty.
Where The Island Meets Design
Building on sloped, waterfront land here comes with real risk. Get a retaining wall wrong on Mercer Island, and you're looking at erosion, a failed inspection, or worse.
Mercer Island regulates grading and earthwork, with seasonal limits in some areas, so timing your project matters as much as designing it. Several key areas sit within landslide hazard zones, and significant tree removal requires city review before any work begins.
A landscape designer working on Mercer Island has to solve for these conditions before drawing a single line, not after. Our team plans around:
That local knowledge is what keeps a beautiful design from becoming a construction problem later.
What We Build
Each service is part of one integrated design-build: designed and constructed by the same crew, from first concept to finished yard.
Licensed, Warranted, Accountable
Our team is licensed, experienced, and backed by a warranty on every completed job, with clear expectations set from the first conversation.
We hold Washington State Contractor License ANGKOI*750PA, current and verifiable for every project we take on.
Our professional team brings over 50 years of combined design and construction experience to every Mercer Island property.
Every project completed on Mercer Island carries a 5-year workmanship warranty — a commitment that covers the build long after the crew has left your site.
We've completed 548 landscape and hardscaping projects across Greater Seattle, giving us real experience with island-specific conditions.



Serving Every Corner Of The Island
Every part of Mercer Island presents different conditions — waterfront lots come with slope and shoreline setbacks; interior parcels deal with tree canopy and limited sightlines. The work we do on a North End property looks different from what a South End lot needs.
How We Work
Every project starts with a conversation about your property, your goals, and your budget. From there, we guide you through design, permitting, and construction as one smoothly connected process.

In Their Words
Mercer Island homeowners consistently mention the same things: responsive communication, a reliable crew, and a finished landscape that matches what was designed from the very first consultation.
Recent Work
We recently completed a front yard transformation in Mercer Island, turning an underused space into a well-designed landscape that improved curb appeal and how the family uses the property.








Our Approach
Luxury landscape design Mercer Island projects demand more than good aesthetics. They require an understanding of how the island's terrain, tidal buffers, and municipal code actually affect what can be built — and where.
We plan around the soil and drainage conditions specific to Mercer Island, because generic assumptions lead to drainage failures later.
We manage waterfront slopes to control erosion on shoreline properties, designing retaining structures and drainage systems suited to each site's grade and exposure.
Mercer Island enforces strict codes for impervious surfaces, grading, and tree removal. We handle permitting in-house so that regulatory requirements are built into the design from the start, not addressed as a delay later.
Native plants establish well in Mercer Island's soil and climate, supporting the local environment while requiring less irrigation and maintenance over time than non-native alternatives.
Simplify Your Yard
Mercer Island's tree canopy and variable light conditions mean the wrong plant in the wrong spot creates maintenance problems that compound over time. Low-maintenance landscape design Mercer Island homeowners ask for starts with selections matched to each property's actual sun exposure, soil type, and drainage, keeping the yard manageable through every season.
We choose native and drought-tolerant plants suited to Mercer Island's growing conditions, which need less water and maintenance than non-native alternatives once established.
Mulch retains moisture and helps maintain healthy soil, reducing how often garden beds need attention.
Drainage and irrigation planned for sloped Mercer Island lots manages stormwater runoff and reduces the maintenance burden over time.
Front yard refreshes follow the same low-maintenance principles, improving curb appeal without adding new landscaping upkeep to your property.
