A Passion for plants... and more!

We love plants but that’s not all we do. Based in Rhode Island, Soto Design is a full-service design firm specializing in detailed high end residential landscape design.

What can we do for you?

Committed to the highest level of professional service, Soto Design offers the following:


Landscape Master Planning

Conceptual plan of space outside the building including the driveway, parking court, foundation plantings, walkways, terraces, pool layout, play space, display and kitchen gardens, screening etc.


Project Cost Estimating

Itemized budget estimate based on current contractor prices. This is helpful once a master plan is complete; phasing may be necessary to accomplish the goals of the overall master plan.


On-site Consultation

Evaluation of existing landscape/gardens. Prepare a "memo" of recommendations. Drawings may or may not be necessary.


Invasive Plant Management

Prepare plan for approval by CRMC or DEM for removal of invasive plants along sensitive waterways and propose restorative plantings. Typically a plan is carried out and monitored within a 3 year period.


Construction Observation/ Plant Layout

Monitor construction or planting to ensure the design is carried out per the client's approved drawings. Clients may alternatively chose to take a plan and implement themselves where we can answer questions as necessary.

Other services upon request include: container plant design, garden art sourcing and placement, furniture sourcing and layout, fine gardening, floral design and event planning.
