Second-Story Additions

When the lot is just right but the house is too small, going up can be the elegant answer. A second-story addition adds bedrooms, a primary suite or a retreat with views, and it keeps the outdoor space you love. It also asks for careful engineering: the foundation, walls and framing below must carry the new load, and the new floor must tie into the old structure.

We start by evaluating what you have, then work with engineers to reinforce where needed. Once the roof is lifted, we build the new floor quickly and weather-tight, and we blend the exterior with matching brick, stone or siding. We plan stairs, mechanical routes and temporary protections so you know what to expect during the process.

FAQ

Common questions about second-story additions

Can any house take a second story?

Not always. An engineer reviews the foundation and framing first, and reinforcement may be needed.

Will I need to move out?

Often during the roof-off phase, and sometimes for the whole project. We explain what to expect before we begin.

Will the exterior match?

Yes. We design and detail the new level to blend with the existing materials and proportions.
