Used Creative Environments for a new home from Toll. I cannot say enough good things about CE and Haley as a designer. She "nailed" the design aspect and was very flexible as we made changes along the way (the process took about 12 months - due to a long build time from Toll). All landscaping (including pool) was complete within 2 weeks of closing date and follow-up along the way has been extraordinary.
There have been some plants that have died along the way (not unusual for 300+ plants) but some of those have simply died, while others have been eaten by rabbits, coyotes, etc. in the neighborhood, and CE has gladly replaced and looked for better varieties that are less appealing to the wildlife in the neighborhood - while still being visually appealing.
Overall - the design, responsiveness, and follow-up and great. They may not be the cheapest (a large part is likely because of the kickback to Toll for being allowed in during the construction process) but we are very happy with job and use CE and Haley again for our next home.
