The design process begins by studying the site and listening to the client’s vision. The Lesslie sketch concepts and refine them into an initial design. They engage with local jurisdictions, present the concept, and generate construction documents for pricing. After reviewing pricing with the client and builder, they finalize the design and provide all details for construction. They act as the agent of design, coordinating other disciplines to create a cohesive drawing set. Throughout construction, they maintain regular contact with builders and craftsmen, conducting site visits for inspections and answering questions via phone, text, and email. After the client moves in, they generate a final punch list and remain available for future questions.

The firm’s portfolio includes completed projects such as Rivercourse, Ocean Escape, Seascape, Marshview Haven, Home on the Bluff, Sanctuary, Cassique III, Kiawah Coastal, Cassique II, Ocean Park III, Ocean Park II, Cassique I, Ocean Park, Settlement, Shingle Style, Tranquil, the Lantern House, the Retreat, Haven, Serenity, the Savanna, and Sketches.
