About Us

We are a custom design builder of additions, home renovations, and custom homes. The most important aspect of our business is exceeding our client’s expectations while building exceptional quality into every project. This in turn builds a client base that we work with again and again. Nearly all builders claim to be custom builders, but "customizing" options may be limited to choosing between two types of cabinets and three flooring options. Winthorpe is able to design & draw plans,work with challenging existing conditions, and your specific tastes to pull together a well-conceived, aesthetically pleasing, and lifestyle functional result. The scope of our work can be large or small; from large custom homes to smaller renovations. Our work includes: Renovation, Additions, Kitchens ,Custom Homes, Bathrooms, and Whole home renovations As Scott explains,"We need to get to know our customers as individuals before we begin a job. From there, I think it's our job to guide them through the project. Projects are more than just blueprints! Our distinction lies in how we reach solutions that will satisfy the homeowner." Again, the most important aspect of our business is exceeding our client’s expectations and ensuring their happiness. That's why Winthorpe's greatest source of business is from customer referrals and repeat business.The best way to understand what we are about is to call us. You'll soon see why homeowners love to work with us!
