Carol completely transformed our boring old Chicago back yard into a gorgeous extension of our house. It's like we have a whole new huge room to enjoy when the weather is nice. I cannot recommend her highly enough. She is very experienced and came highly recommended by her past clients. They raved about her work and they were spot on. Carol came to the project with great ideas, remembered every detail of our wish list and was flexible when we asked to change the plans a bit. We needed a stone patio, new fence, sidewalk, back stairs and porch, raised garden beds and all new plants, plus we added some plumbing, lighting and new electric to our garage. She arranged for all of this to be taken care of by her expert team. She's a one-stop shop. And her crew! They're an amazing, friendly, hard-working, knowledgeable group of people. They started on time every day, cleaned up after themselves, and the foreman was always available to answer my questions. They seemed to really enjoy their work. My neighbors were like: "Where did you find them!? They were amazing!" It's no wonder that Carol is highly sought-after and very busy. We were lucky to get her. We started planning and made decisions in the fall, so that by early the next spring, we were ready to roll.Read More

Carol has redone both our front and back yard. Each each presented their own challenges ...from many mature trees and shade to a lot of overgrown, unkempt plantings. Carol listened to our ideas/goals and was able to transform them into detailed plans and great spaces. We wanted simple, low-maintenance plantings for our backyard as well as a large fire pit area. She was able to utilize a lot of already existing materials (flagstone, some plants, etc) which was great. We didn't feel as if we were wasting anything and it helped save on costs. She also fixed a lot of of paver patio which was uneven and dangerous. She just completed our front yard and it exceeded our expectations. She sourced a very specific evergreen tree that I had seen online. She bought it weeks ago and took care of it at her house until it was time to plant here. She was able to fit into the design as well as a specific tree my husband wanted. She really pays attention to details, from the stone she uses, to the variety of plants she suggests to the pavers she recommends. Her crew is great. They are really professional and go above and beyond what we would expect. We had stone delivered to put under our deck, unrelated to anything Carol was doing for us. We just dumped the stone under the deck and didn't hadn't had time to spread it out. It was certainly not on their to do list and they spread out the stone for us. Little things matter. I found Carol easy to work with and she is going to be doing our side yard hopefully in the near future. Highly recommend! (I wish my pictures were better...hard to see the details.)Read More

From start to finish, a fantastic project. Front, side, and back yards, hardscaping and landscaping were needed following a renovation. Carol met with us and listened to what we wanted and needed and developed a project plan that her team brought to life. Work was done professionally and efficiently with attention to detail and we genuinely enjoyed every part of the process. Highly recommend.Read More

We came across Carol's work while searching for someone to reimagine the overgrown garden bordering our side lot, and her designs stood out immediately. After a thorough site visit, Carol took our loose ideas for the space and created an absolutely incredible and inventive design that far exceeded our expectations. Carol also suggested additional landscaping to replace the lackluster planting in front of our house, and her addition freshened up our home beautifully! She knew we were planning a backyard wedding in a few months and rearranged her team's schedule to make sure our planting could in before the winter, which was generous and much appreciated. During the installation days, her team was has fast, professional, and extremely neat. She'll be back in the spring to add two custom-built arbors, and we cant wait to sit under them and admire our new landscaping as it grows in. Our family is very excited to enjoy the lovely space that she has created for us for years to come!Read More

We tapped Carol and her very talented and professional crew to turn our tiny urban backyard, which was sad and overgrown, into a lovely and modern space that we can use to stay sane through the pandemic. We loved her plan from the start -- and we aren't the easiest people to please. They put in tiered decking, new fencing, and plantings, removed some weed trees, and built in a space for our soon-to-be-delivered hot tub. We are thrilled with the result! Soup to nuts, they did it all and were among the best contractors we've every hired.Read More
