Focusing on custom design and residential remodeling, our firm is skilled with a full range of construction styles and services.


Planning is the foundation for all successful projects, construction or otherwise. At Tangent Sphere Inc., we employ the latest construction design technology and the most creatively experienced professionals. We take design to a new level with
