Builder Story

Quality homes are built on good relationships.

This foundation of commitment was rooted early in this brother-sister design/build team. Katie Lewis and Justin Ganzer, owners of Signature Homes of Colorado, were exposed to quality custom home building by their grandmother, Ms. Jane Marquiss of Jane Marquiss Construction, Inc. Her guidance and teachings are the foundation of this successful design/build construction team.

Every home is unique but every project should receive the same level of personal attention and depth of expertise. As a design/build firm, Signature Homes of Colorado retains single-source responsibility from start to finish. We know that it takes a careful balance of ideas, creativity, communication and organization to make your dream home a reality.
