He came up with a fantastic design, provided guidance throughout the entire process, and provided us with an outdoor space that is amazing. **Comment from Land & Water Design:** > Thank you Nick & Shin, you made Craig Smith, BR Design/Build Contractor, O’Kelly Russell, Land & Water Design’s landscape architect associate and my job easy. Your decisions regarding LWD design, landscape choices and the suggestion for using Belgard pavers & wall material. Only item left is the new composite fence which will be installed this week. Enjoy the remainder of the summer making memories with your family & friends in your new backyard. > Thanks for sharing the Before photo. **★★★★★ — Jessica Gada, April 2024** > We are thrilled with the work that Land & Water Design has done for our backyard. Our yard and pool had not been touched in decades, and they completely revived it. Don incorporated the complex topography of our backyard and the aesthetic of our house to create a unified, flowing, beautiful and practical space. From hardscape (all new retaining walls, dining spaces, and shade needs) to native plantings (including thoughts about how to easily maintain the plants and trees), there's not a single detail they didn't consider. Their communication, consideration of our needs and wants, timeliness, and selection of supporting teams/contractors is above and beyond. We couldn't recommend them more, and look forward to using their services as we continue to add onto our project in the near future! **★★★★★ — HU-278980845, Sept. 2023** > Don was excellent throughout the process. His experience and creativity in designing water features are tremendous. He was professional, courteous and engaged. Even though he was suffering with serious back issues, he was consistently present and engaged in our project from design to the completion of the construction. I highly recommend him and his company. **★★★★★ — HU-344702348, Sept. 2023** > I have worked with Don and his team at Land & Water Designs for over 10 years. I would recommend them to anyone looking for their dreams to come true. Don attention to detail and craftsmanship are top notch! **★★★★★ — TB, Sept. 2023** > Land and Water design represents the benchmark in HARDSCAPE design and integration into the GREENSCAPE. From coping to cooking; fire pit to wine fridge; shade structure to paving slabs I trust the team at L&W Design. If a personalized outdoor living space is on your wish list you can’t go wrong with the experience and creativity of Don! **★★★★★ — Techo Taphouse (Southeast Hardscape Consultant), Sept. 2023** > I have known and worked with Don and his team for almost a decade. Don has been a trend setter for the outdoor living industry for even before I met him. He was on the cover of the Techo-Bloc catalog multiple times and is as talented of a designer as any I have met. He cares about his customers and is simply a great person. I highly recommend Don and his team at Land & Water Design! **★★★★★ — Hiep Dao, Feb. 2022** > We used Land and Water Design to design the hardscape and decking for our pool project in McLean, VA. They did a very thorough job and came out to discuss our wants/needs for the project. They did a great timely job in getting us the plans quickly as we were still bidding out the pool projects amongst pool builders in the area. We also had a long extensive variance process with Fairfax County that complicated matters as we were restricted what part of the yard we could use for the construction of the pool and deck. Don did a great job with the design and it looks great. Unfortunately we were not able to use the design as it was over our budget and violated the variance parameters but it gave us some really good ideas for our eventual build. They were very professional, timely and great with communication throughout the process. I would highly recommend Land and Water Design. **★★★★★ — c\|s DESIGN STUDIO LLC, Jan. 2022** > We hired Don from Land & Water Design to help us design a refresh of our pool and backyard, as well as a master plan for our property in Fairfax Station. Don was very responsive from the first phone call and we immediately synced up well in terms of design philosophy and approach. So much in fact that we didn't interview any other designers for the project! I am an Interior Designer and had some initial ideas, but wasn't sure how to implement. Don was great in educating us and listened to our dreams for the project. He came up with a wonderful design that was even better than we imagined. We are currently in construction and seeing it come to life is amazing! Thanks Don and Mike for all your expertise! **Comment from Land & Water Design:** > Christina & Scott thank you for being great clients and providing this review. **★★★★★ — Nina Smith, March 2021** > Land and Water Design has more than met our expectations. Don is so easy to work with and very responsive to every text and phone call. His design is exactly what we wanted and we cannot wait to enjoy our backyard oasis this summer! **Comment from Land & Water Design:** > Nathan & Nina, thank you for your review and your confidence in Land & water Design. It is exciting seeing the early stages of your backyard pool, hardscape and landscape coming together. Before you know it you will be sitting on your oversized sun shelf enjoying the sound of the sheer descents from the 3' raised fieldstone bond beam not missing the ambient noise except for the birds & nature. Cannot wait to see the finished product! **★★★★★ — Gibson Dunn, May 2019** > Don was wonderfully creative and responsive in designing for our somewhat difficult site. The final design and its construction were beautiful, artistic and dramatic. We thoroughly enjoy the fountain, water feature and lighting. It is everything we hoped it would be. **Comment from Land & Water Design:** > Gibson & Cheryl, thank you for your review. We were challenged with the site due to the limited access to the backyard but are very happy with the finished zen-like water feature you requested. The sheet decent waterfalls and masonry planters and lighting really put the finishing touches on your outdoor living space. **★★★★★ — Justin H., May 2019** > We hired L&W in the fall of 2017 to design our landscape plan for a major pool deck and and patio installation. L&W was prompt, professional, and great to work with. Their knowledge on design, materials and technology made our decision making process much easier. We ultimately expanded L&W's scope to include finalizing designs for a pool house and generation of drawings for permitting, etc. Don and his team worked seamlessly as needed with our contractors to ensure construction went as planned. We couldn't be happier with the result. Photos to follow! **★★★★★ — Don & Alison Seaborn, Dec. 2018** > We would highly recommend Land & Water Design. We had been searching for years for someone to design a deck and backyard for our unusual space. Don was the right man for the job. Not only do you get Don's design and expertise you get his amazing and highly skilled team of contractors. Don listens to your vision for your space and comes up with a design that will blow your socks off! From start to finish and all the changes in-between Don and his team provide highly quality work and a beautiful end result. > > We couldn't have asked for a better design/build team. Our backyard is a beautiful oasis that will provide many wonderful memories our family will enjoy for years to come! **Comment from Land & Water Design:** > Thank you for the review. We enjoyed working with you and appreciate your recognition of our work. We hope you are enjoying your swimming pool and spa with the waterslide and fire pit for years to come. The porch and kitchen overlooking the pool and sunsets must be your favorite family and friend hangout. ## Selected projects - [Custom Pool Sorrel Grove](https://www.houzz.com/hznb/projects/custom-pool-sorrel-grove-pj-vj~7274022) - Location: Ashburn, VA - Photos: 12 - Description: This custom swimming pool and water feature was designed to fulfill our client's "wish list" for a small residential pool with a large tanning ledge and a Techobloc Blu 60-paver patio.

A: The face of the treads & wall caps are hand split rock edge. **Q: Wall material?** *(in Photo Questions)* can you share details regarding the stone used on the retaining walls? A: Select Maryland fieldstone veneer. **Q: heron sculptures** *(in Photo Questions)* Where were the heron sculptures purchased? They are nicer than what I usually see. A: Your welcome **Q: pool depth** *(in Photo Questions)* what is the greatest depth of the pool? A: The depth of the pool is 5’ on the deep end are a swim jet system. This pool is a townhouse backyard in Alexandria, VA designed & built in 2005. Pool dimensions are 12’x32’ **Q: Slide** *(in Photo Questions)* This is one long waterslide! Who are the main manufacturers of these slides, and what would be the cost for installing, let's say, a 15 foot slide as part of a new pool build? Thanks A: The slide is manufactured by Dolphin Waterslides. Call they can answer your questions regards to cost which will be different due to rise in material costs. Our slide was $25k when it was completed 25 lf (3) poured in place reinforced concrete 18” diameter piers. Dolphin Waterslides PO Box 486 153 E. Main Street Adamsville, TN 33310 Bren & Lisa Thomas 731-632-1407 **Q: 12' by 40' stone wall is it safe?** *(in Landscape Design)* There is a 40' wide 12' tall stone (quarry?) wall at the back edge of my property. On the top of the wall and heading back 120' is the backyard of the people behind me (they can stand on the edge of the wall and see my property below. The wall has been there since the late 50's. When it was built, they used a small pulley crane, and the rocks were perfectly cut to match and laid on top of each other (straight up and down). Therefore they were not binded together (no need because it was solid). The wall is now covered in ivy with a couple small trees growing out of it. I'm nervous about it's structure. Should I be? (I have no idea about these types of things). Whom or What type of professional contractor can I have to come out and inspect it for safety? It's probably safe, but this year I will be working at the base of it to remove all kinds of under brush and weeds on about a 5' strip of land (that sits behind a fence). I'm nervous about some sort of rock slide, or pulling one of the trees out. It's not bowing excessively, but it has shifted over the years just a tiny bit. How can I remove those trees safely from the crevices? Do you think it's safe to work underneath to clear the brush? (to whom can I ask?). Is it still a solid structure? -Joe A: As a registered landscape architect, I’d suggest investing in licensed structural engineer who can assess the wall’s structural integrity. Does the wall have a batter, which is a determined recessed angle that continues to the top of the wall with the final appearance, the wall appears to be leaning into the slope. The structural engineer would be the best professional call. --- *Source: Houzz professional profile. Reflects the profile as of 2026-09-06.*
