KCS Residential Design


About Us

The KCS aesthetic is fueled by a passion for fusing traditional and contemporary design elements and blurring the lines between indoor and outdoor living to create a timeless home that meets a client's needs through every life stage. Beyond beautiful design and thoughtful floor plans, KCS seeks to leverage Sophia's development expertise to its clients through a consultative approach to the design process. By sharing insights into how design decisions impact building costs and by providing estimated construction costs during the design process, KCS helps clients make informed decisions. KCS also believes in passing its trade prices to its clients. The KCS team is often called upon to meet with prospective buyers who are contemplating the purchase of a property that needs vision and know-how to see its full potential.
