Our story
Founded on a simple belief: a garden is never finished, it’s alive
Sage & Stone began in 2008 with two people, one truck, and the conviction that landscaping should be led by horticulture — not just hardscape. Today our studio of designers, stonemasons and plantspeople crafts outdoor spaces across the Portland metro, and still walks every site before drawing a single line.
We build with local stone, plant for pollinators and drought, and stay with your garden long after the crews leave — because the best landscapes are the ones someone keeps loving.
- In-house design studio and construction crews — no subcontractor roulette
- Native-first, climate-resilient planting palettes
- Transparent fixed-price proposals, phased to your budget

Kind words
What our clients say, seasons later
“They didn’t just build a garden — they understood how our family lives and designed around it. Two years on, it keeps getting more beautiful.”
“The crew treated our property like their own. On budget, on schedule, and the stonework is honestly art. Neighbours stop to ask who did it.”
“We tried three maintenance companies before Sage & Stone. The difference is night and day — actual horticulturists who know every plant by name.”
