How Steve Lanning Works

Instead, you will work directly with the owner of the firm, a highly knowledgeable and experienced general contractor who manages every project with full responsibility for the outcome.

To maintain high standards, strict attention to detail is necessary and can be achieved by using only quality manufacturers, a personalized service approach and by having a single person responsible for the outcome.

“We are very pleased with the finished building and receive wonderful comments on how it looks on the outside and how clean and functional on the inside. Steve’s team did a great job of constructing the specified building on time and for the exact price quoted.

He took our architect’s rendering and quickly created build ready plans. He was patient reviewing the finish options and great to work with on all phases of the project. From start to finish and through the entire process, we are very pleased with our winery building and with Lanning Construction.”
