What You Can Expect When Building a Second Story with Lamont Bros.

Planning a second story addition can be an intimidating task. Not only do you need to design it to look amazing and function well, you also need to make sure it’s structurally safe and up to code. Many homeowners try to achieve this by hiring a separate designer, engineer, and general contractor to get it done.

But, there’s a better way. With the design-build team at Lamont Bros., all of the planning and construction is handled by the same team from start to finish, keeping you in control of the cost, scope, and timeline of your remodel.

Types of Second Story Addition Projects

Every family has different needs, and a second-story addition can be customized to suit your specific goals. Here are some of the most popular types of second-story additions in Portland, Oregon:

Full Second Story Addition

Turn your one-story home into a two-story home by adding a full second story. This type of addition essentially doubles your square footage, giving you room for more bedrooms, an additional bathroom, or even a new primary suite. It’s the ultimate way to expand without moving.

Partial Second Story Addition

If you don’t need a full second story, a partial addition is an excellent solution. This could be adding rooms over a specific part of your home, like expanding above a garage or even adding onto an existing second story.

Second Story Dormer Additions

Dormer additions are a great way to add light, space, and architectural interest to an existing second story or create a new one with character. Dormers can increase headspace in an attic or add an entirely new room while making your home more visually appealing from the outside.

Erik & Amy’s Custom Addition

When they first moved into their home in Portland’s Woodstock Neighborhood, Erik and Amy had enough space for them and their young child.

When they found out that they were expecting twins, the need for additional space in the home became urgent.

Our team worked with Erik and Amy to extend their home further into the backyard, adding a dining room, primary bedroom, and bathroom.

Custom Home Addition

We used Lamont Bros. in 2020 to do a major addition on our home. It was a difficult decision. Should we invest to make our home fit our growing family’s needs or move to a newer, bigger home? Now, with the benefit of hindsight, we are so happy we chose to do the addition. Our space needs are so much better met and we get to stay in a great neighborhood.

Two Story Addition

The Lamont Bros. built an addition on our house about 4 years ago. They helped us refine our plans, they got all the permits, and they did a great job on the addition. They were unusual in that they subbed out very little of the project, instead having their own crews perform a majority of the work. The owners, Joseph and David, are friendly, honest, and competent. Their employees are also hardworking, friendly, and competent. We were very impressed and satisfied with the performance of this company, and wouldn’t hesitate hiring them again.

Second Story Addition + Bathroom Remodel

We’ve had Lamont Bros complete 2 projects at our house over the past 6 years. The first was a major remodel/addition project involving adding/expanding rooms on the main and upper floor and remodeling a bathroom, while the second was a bathroom remodel. Both projects were handled with great attention to detail, from initial design through finished product, by some of the nicest people in the world. I highly recommend Lamont Bros any chance I get with family and friends for any design/build project, and I gladly recommend them to you too.
