The Story
Homebuilder Randy Sebastian in Lake Oswego OR - Renaissance Homes

It takes dedication and passion to make a
great home builder.

Our President, Randy Sebastian, has deep roots in the Portland area and is passionate about our great city.  He grew up in Oregon City and attended Portland State University. He began building homes in SE Portland in 1984 at the age of twenty. The following year, he founded Renaissance Homes.  Since then, he has continually refined and improved the home building process. His work continues to reflect his enthusiasm and excitement, thus creating one of the most acclaimed local home builders in the Portland area.

Randy has a passion for what's right in a home.

With his artistic eye, combined with an acute understanding of the wants and needs of homebuyers, Randy has set a course for the company to construct every home to the highest standards.  Renaissance utilizes our Living Green building process encompassing energy efficient technologies and innovative green products. At Renaissance, we believe we are helping to save our planet one Renaissance Home at a time.

Innovation is at the heart of every home built by Renaissance. Our creative team pushes the envelope on home design, construction techniques, amenities, style and new products. We lead, others follow.

Renaissance home buyers are the obvious reason for our success. 

We work hard to offer better designs in premium locations and to make building your new home an exciting, enjoyable experience. Teamwork often goes unspoken.  Not at Renaissance.  We work hard at it each and every day.  Every home, right down to the last detail, is built with sincere care.

Renaissance Homes is the proud winner of 40 Street of Dreams awards, including 6 Best of Show, more than any other builder, ever. Renaissance Homes is the largest builder of single-family ENERGY STAR certified homes in state of Oregon. We are dedicated to creating homes of unparalleled quality and value.

Open Web Floor Trusses Icon

Open Web Floor Trusses

Open web truss joists allow mechanical system installations to be within the floor's framing, allowing all of the air ducts to be run between the floors. This eliminates ducting in the attic or crawlspace and saves energy by NOT pushing heated air into a cold crawl space in the winter or sending cool air into a hot attic in the summer. For more information of open web truss' please refer to our PDF.

Blower Door Testing Icon

Blower Door Testing

Air flowing in and out of a home can cause lots of problems. Air leakage can account for 30 to 50 percent of the heat loss in some homes. This is one reason why Renaissance Homes conducts a blower door test through a professional energy auditor upon completion of every home. It helps to determine the home’s tightness, reduce energy consumption due to air leakage, avoid mosture condensation problems, avoid uncomfortable drafts caused by cold air drifting in from the outdoors and make sure that the home’s air quality isn’t too contaminated by air pollution. For more information and to learn about how blower door testing affects a home EPS score click on our PDF.

Indoor Air Quality

The air inside your home makes a difference in how you feel every day, and indoor air quality is a high priority in the construction of a Renaissance home. With features like air filtration systems, controlled ventilation and low-toxic building materials, a Renaissance Home may allow you to breathe a little easier. The same building materials in a Renaissance Home that improve indoor air quality also contribute to a cleaner environment, as less toxic products reduce environmental pollutants.

You have highly trained professionals who were a pleasure to work with!
Working with your team to buy and build a Renaissance home was a pleasure. Once I found your Vintage designed homes...Viola! I was impressed then, and remain so now, with the care and quality with which you build. You have highly trained professionals who were a pleasure to work with. They were so friendly and made the entire process fully enjoyable.
We really are impressed with the quality and aesthetics of our home. Renaissance lives up to their reputation.
Our Construction Manager was an absolute pleasure to work with and always addressed any concerns in a timely and professional manner. The Director of Design and staff were fantastic to work with, especially since 99% of our selections were made over Skype due to us being abroad the majority of the time our home was constructed. We really are impressed with the quality and aesthetics of our home. Renaissance lives up to their reputation.
We couldn't be happier!
We couldn't be happier with the location, view, floor plan, workmanship, energy efficiency, quality features and safety of the home you all had a hand in building for us!
Buying a Renaissance home is truly a dream come true.
We so appreciated working with your team. You made it so easy. Our house is by far the most beautifully made house I could have ever hoped for. We love everything about it. Buying a Renaissance home is truly a dream come true. I know very well the quality reputation, even among other builders. We feel very blessed to raise our children in such a beautiful home.
[He has] excellent problem-solving skills, knowledge, and expertise. Very Professional.
Your Construction Manager was the best!! He has excellent problem-solving skills, knowledge, and expertise. Very Professional. One of your Realtors was our first "face of Renaissance" and she had just the right combination of being approachable and professional. She immediately put us at ease and made us feel comfortable in pursuing making an offer on the home.
We "LOVE" our Renaissance home. Absolutely perfect!!
We "LOVE" our new Renaissance home - any issues we've encountered (supremely small) have been taken care of ASAP. [Our home is] absolutely Perfect!
We'd like a second one!
We like everything about our home. In fact, we'd like a second one!
[Renaissance Homes] care[s] about the environment, the customer, and the communities where they build.
Construction, installations, and overall workmanship were impeccable! Renaissance homes are designed and constructed by true craftsman. They care about the environment, the customer, and the communities where they build.
I think the idea of building in established neighborhoods is brilliant.
Your Quality Assurance Field Specialist is remarkable in his attention to detail, addressing small issues that I would have never noticed. My daughter had been living in a Renaissance Home for 2 years before I purchased this home. I think the idea of building in established neighborhoods is brilliant.
Beautiful, Elegant Home!
Thank you, Renaissance, for the beautiful, elegant home and the consistent commitment to excellence demonstrated by your staff and subcontractors throughout the construction process!
