Distinctive and Inspired Landscapes & Pools

Our mission, at Johnsen Landscapes & Pools, is to transform properties into outstanding outdoor settings that are truly enjoyable. Imagine sitting in a peaceful terrace garden surrounded with flowers or entertaining friends by your new pool and spa.  That is our specialty. We create a site and landscape design of your grounds illustrating whatever it is you desire – an elegant swimming pool, inviting front entry, rear terrace and flower garden, meditative green space, or impressive entry drive – and then utilize our expertise to guide the overall installation.

We serve many counties in the NY and CT area: Westchester, Putnam, Dutchess, Columbia, Rockland, Orange, Ulster, Fairfield and Litchfield Counties; as well as New York City Boroughs. We also have projects in Massachusetts, Maryland and Florida.


Our process begins with an initial on site discussion about your landscape ‘wish list’ and identifying the unique possibilities of your property. We then prepare a design services proposal based on our discussion.

Upon acceptance of our proposal, we move forward with developing a detailed design for your property. Once your design is completed and approved, we are available to ensure a smooth and successful installation of your project.
