Where did you grow up?
Justin Ganzer and Katie Lewis are a brother-sister design/build team.  Both born in Wichita, Kan., and moved to Grand Junction at an early age. They both graduated from Fruita Monument High School.

How did you get started in the building industry?
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. Katie went on to study interior design, and obtained her bachelor’s degree in interior design and construction management.  Justin is a licenced Master Electrician with more than 20 years experience in general construction. (See photo of our grandmother at left.)

How has the industry changed since you got started?
Buyers always have been very educated, but now with all of the on line tools and design applications it exposes them to even more ideas and styles. Through our design/build process, we are able to better see their vision and integrate these ideas into their home in a way that fits their lifestyle and their budget.

What should consumers look for in a new home? What kind of questions should consumers ask a builder before they sign a contract?
Consumers should look for a home that will fit their lifestyle and grow with their family. As well as utilize products and materials that fit their needs. In interviewing a builder, it’s most important that the homeowner trusts their builder and has a good, constant line of communication. They should ask questions relating to their construction process: What it looks like from start to finish, how they manage the overall construction budget, what their fee structure is, what sub-contractors they work with, and request a list of client referrals.  A referral from a past client is our biggest compliment.

Is there a particular style of home that you consider your specialty or prefer to build?
Every home we build is customized to the homeowner ... it’s our design/build concept. We don’t have a primary focus on a certain style, we build each project to the design tastes of the owner and the way they live.

What is the most unusual feature you’ve put in a home?
We try not to be “trendy”, we strive to be timeless, utilizing features that promote modern living. We are innovative with each space, and Every space has a function and a purpose specific to the needs of our client.

What do you enjoy when you’re not working?
Justin enjoys the outdoors; hunting, mountain biking, and camping.  Katie loves sporting events, running and spending time with family and friends.

Justin is married to Lori Ganzer and has 2 daughters Madison (9) and Sadie (6). Katie is married to Ryan Lewis and has 2 boys Jackson (7) and Grant (4)

What do you enjoy about living in western Colorado?
Western Colorado is a great place to raise a family and run a small business.  We appreciate the small town atmosphere, and relationships that we are able to build among the community.  As well we love the outdoors, so western Colorado provides recreational activities year round.

What do you see as up-and-coming trends in the building industry?
We see the importance of executing a careful balance of ideas, creativity, communication and organization. This unique process helps the construction project be efficient, exciting, within budget and personalized. This design/build advantage is the alternative construction concept integrating interior design and general contracting to provide a single-source responsibility from start to finish. Clients today don’t want a cookie cutter home ... they want their ideas based around their lifestyle.
