That's up to you! But rarely does any design β landscape, interior, or whole home β get built exactly as scoped. We encourage you to think of your conceptual designs as a communication tool to convey a vision to your licensed landscape contractor.
Your final designs will include either CAD plans or 2D landscape design plans with approximate dimensions, planting layout, specific plant name, and basic materials callouts, but many last-mile design decisions and materials selections will be made in the field with the assistance of your contractor.
Remember that your design team is just a chat or an email away if you ever need support during this process!
