Whether you're planning for a new bedroom, a expanded living area, or a guest suite, room additions can make it happen.

What Home Addition Work Entails
Room additions are a broad category that span everything from adding a single bedroom to full second-story additions. At their foundation, room additions mean physically extending your home's current floor plan — either horizontally or vertically. This is different than remodeling, which works within the current square footage.
These undertakings demand a full range of trades that brings together architectural planning, city approvals, foundation work, structural carpentry, electrical, plumbing, insulation, wall systems, and flooring and trim. Because room additions involve multiple building disciplines, hiring a general contractor who can coordinate each phase is the key to a smooth project.
Room additions are commonly chosen by homeowners who have outgrown their current layout but prefer to stay in place. They're often the right move for families welcoming new members. Whether it's a small bump-out or a full-scale addition, the process follows a well-defined set of stages that our team have refined over many years.
