About Us

Precision Designs is a full service residential design firm located in McKinney Texas. Jay Wojnas started Precision Designs in 1998 taking with him years of experience working for prominent Dallas home builders. Jay saw a need for a company that would stop and listen to their clients. We offer as much or as little direction as the client needs. Precision Designs has won several home design awards and designed homes in the Dallas HBA’s Parade of Homes. We can design for a broad range of styles and budgets. Maybe you are a first time buyer, who is cost conscious, and wants a modest ranch style home. Or perhaps this is your very last dream home and you want a palatial, one of a kind, French provincial estate home. At Precision Designs, our philosophy is not to place our interests above our clients. We listen carefully to what our clients say and create for them exactly what they want. Creating your home your way sets us apart from other design firms.
