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

Sarah, Heather, Blythe, Alexis

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.

Blythe Yost, Landscape Architect & CEO
The Tilly design team is led by Blythe Yost, who has been practicing landscape architecture for over 15 years. She is the principal and founder of two high-end landscape companies, whose projects include everything from contemporary courtyards in Brooklyn to multi-acre estates in The Hamptons. Yost graduated from Cornell University with a Bachelor of Landscape Architecture and a focus on horticulture.

We have found the Tilly process to be most successful on properties less than an acre.

A major part of remote design is understanding a property’s existing conditions and limitations. To do this we generally use the primary structure (usually the house) as the main point of reference. The greater distances are from from the house the less successful we are at understanding your property. No matter what the size of your property, the more information you can provide us, the better. Don’t be shy with the pictures! And please send along any and all architectural or property plan documents you can.
