“During the hearing, Rucci and New Canaan-based landscape architect Keith Simpson of Keith E. Simpson Associates —a landscape architecture and environmental site planning firm—spoke to some of the unusual facts surrounding the property, such as that its 14,266-square-foot French-style manor house hasn’t been occupied in decades.”
Their office helped us create our beautiful pool area and patio for our family. They were very responsive and knowledgeable, and we couldn't be happier with the results! Highly recommend!
Extremely knowledgeable about all things wetlands. Very professional, loads of contacts in the industry, and easy to work with. I highly recommend them.
Real landscape architects...not garden designers! Love their work.
Their work is not as great as they would have you believe it is.
If only the work was half as good as they say it is. Overpriced and generally leads to dissatisfied customers.
