"We had an outstanding experience with Sean and Bzr team. From the initial call with Gaby to the finished product. I highly and strongly recommend BZR. We first started with a bathroom addition and ended up with an ADU project which turned out great adding a kitchen and 3/4 bath. It did take time and many changes, I want to thank Sean for his patience. I would absolutely in a blink work with them again. I will upload photos when wife has finished furnishing."

Above all, we are watchful of our customer's interests, and make their concerns the basis of our business.

"I had Okay Construction renovate my entire house, including the kitchen. They also changed the electrical panel, all floors, windows, and doors; built new stairs; and installed several skylights. They can do pretty much anything you ask. Bo is very easy to communicate and work with. We needed to move in from another state, and he made sure my second floor was ready when we needed to move by having many staff members work long hours and on weekends. They turned my old house into a beautiful, bright home. Bo can recommend where to look for renovation materials and where to get contractor pricing. We applied for permits for all major projects, and Bo took care of them for us. They also have a warranty, so if anything goes wrong, he'd be happy to come back and fix it. Bo keeps his promises and is very patient. One of our ovens wasn't working right out of the box, and he took it out and re-installed it (and the replacement) many times. He also has many good ideas for small touch-up project"

FAQs for addition to existing structure building service projects in Auburn, WA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
