"We would highly recommend Superior Building Concepts for your next project. After many over priced quotes, underpriced quotes with a wink and a nod to do this small job without permit, or contractors that stopped by to provide a quote that we never heard from again we received a referral from Angie's list for Superior Building Construction.  Stan came by, gave us a reasonable quote then followed up with a very professional and complete contract.  We signed with Superior and were pleasantly surprised with the continued professionalism.  We received compete drawings with architectural choices.  After our selection, it was put through the permit process.  At each point we received proper communication from Stan. Once construction began, Stan was there managing the subcontractors and working alongside.  We were delighted with each subcontractor Stan brought on board.  They were all punctual, courteous and cleaned up everything after their respective jobs were complete. With Covid supply shortages you can imagine some of the issues that arose, but with each roadblock Stan communicated with us and we worked out satisfactory work arounds. This remodel was a pleasant experience and Stan and his team made the difference. You can be confident in your project if you select Superior Building Concepts."

"We hired Steller Construction and Remodeling LLC to build a deck/Catio in May 2024. Micha (the Owner) was straightforward to work with and reach throughout the process. We are retired and live on a set income. Even though we had some lower estimates from other companies, we felt so confident with Micha's (the owner) ideas that, after looking at other reviews/images of this company, we decided to go with Steller Construction. Micha's team was absolutely amazing !!! Ray, our project's lead employee/carpenter, was very knowledgeable, considerate, and had an unbelievable work ethic! The rest of the team did an awesome job as well. They communicated well throughout the whole job always checking in with us to make sure they were doing what we wanted. They were professional and very polite everyday. At the end of each they completely cleaned up the area. We have worked with one other construction company and a roofing company when we did some remodling on our last home and did not have a good experience with either company. We were very nervous about having to go through another bad experience. We were so pleasantly surprised that Steller Construction turned out to be a great decision! Our deck/catio is beautiful and we love it! If you have any construction/remodeling needs contact Micah at Steller ConstructionI you will not be disappointed!"

"Looking for a contractor for your remodeling job? We give John Wood five stars. We hired John Wood of JAW Construction to transform a building shell originally intended to be a shop for building trusses into a small house (officially an auxiliary dwelling unit or ADU) and are thrilled we found him. The job required skills that extended beyond new construction to include the insight, skill and craftsmanship of a highly experienced remodeling expert. He possessed these in spades. Beyond his own expertise, he has assembled a set of sub-contractors that are excellent craftsmen in their own areas of expertise. The job was doubly challenging given that for much of the construction period we were out of state getting our old home ready for sale. This also meant that an extra element of trust was involved. John sent us pictures of the progress, so that we could monitor from a distance. In addition, he was able to identify and rectify several flaws in our design. As with any large construction/remodeling project, there were some unexpected expenses that came up, but John worked with us to help limit cost overruns, sometimes foregoing profits. He was also always up front about the costs of the various components. Our new home is gorgeous and reflects his sharp eye for detail. We couldn’t be happier. In short, if you want a highly skilled, trustworthy, hardworking contractor for your large (or small) job, we highly recommend John Wood of JAW Construction."

"Overall Jay is excellent. He is responsive, always answers texts or phone calls quickly and generally does what he says he will do. Like all construction projects there were small issues along the way but Jay got on top of them and addressed them quickly. Site was clean during construction work, his subs/trades were all good, nice people, skilled workers who did excellent quality work. Overall this was done well and in an acceptable timeframe. I think generally construction could have been executed quicker, there were a few times when no-one was working at the house that could have shaved some time. But, given my extensive experience with construction Jay is one of the good ones ! His estimate was high but he came in well under it and within sight of what I expected things to cost. I will (I am) definately using him again..."

"Silviu was very helpful in assisting me to make some creative choices when remodeling my bathroom. The bathroom is unique and beautiful. He also put new flooring in the upstairs rooms. The work was excellent and was done within a two month period. I plan to hire Oltean Construction again."

FAQs for addition to existing structure building service projects in Lake Oswego, OR

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.
