Tilly’s mission is to make professional landscape design accessible to every homeowner.

Tilly was founded with a goal to simplify the landscape design process for today’s busy and cost-conscious homeowner.
The company was launched in February 2019 by four best friends from high school; one a talented landscape architect, the others business-savvy homeowners who didn’t want to spend a fortune on design.
What started as an experiment and labor of love has quickly grown into an online platform serving homeowners in almost all 50 states. Through a modern design process, Tilly’s clients enjoy a custom experience with a professional designer for a fraction of the traditional cost.
Beyond its passion for helping people enjoy their outdoors through affordable and good design, Tilly is a steward of the environment. The company is committed to delivering eco-conscious and sustainable landscape design, neutralizing their carbon footprint through partners such as One Tree Planted, and supporting local community efforts.
