Achieve Your Dream Addition with An Architect


Design the room addition of your dreams or incorporate upgrades to add a fresh new look to your home. It can seem daunting when you consider all the areas of your home that need attention and an upgrade, but that is where an architect comes into play. Whether you want to create a library with home office, a closet fit for a celebrity, sun rooms to adding a story or a wing to the home, our certified designers and licensed architects create additions to meet your needs, plus our skilled craftsmen build them to last a lifetime.

Why an architect is essential with your new addition 

Not only do you gain more space with a room addition, but it’s an opportunity to improve the exterior look of your home. Mosby’s architects design room additions that harmonize with your existing home while creating new architectural features. With size or complexity of the remodeling, these two factors are why an architect is essential to the remodel process, and to ensure your dream home addition comes true. Beyond expense, there are many factors involved when considering an architect. Do you hire an architectural firm or design and build firm?  With Mosby Building Arts, our in-house architects and design team are with you from concept to completion of your new addition.
