A Cambridge-based landscape design practice dedicated to ecological restoration and native planting.

One Tree Good Day was founded in 2025 by Eva Gildea, a landscape architect trained at the Harvard Graduate School of Design. The practice grew out of a simple conviction: that a well-made landscape should give more than it takes — building soil, holding water, and welcoming the birds and pollinators that belong to a place.

We work closely with each site and each client, reading the existing ecology — light, soil, slope, and water — before drawing a single line. Our designs favor native and climate-adapted plants, layered for resilience and for beauty across every season.

From a first site walk through to planting and long-term stewardship, we stay involved, so the landscape can establish well and grow into itself over time.
