Grand Building and Remodeling has been building room additions throughout the West Valley since 1980. Our Room additions will blend in seamlessly with your existing home. One of the biggest compliments you will receive from your neighbor is that the addition looks as if it was build with the original house. We take great pride in this achievement. We also take the necessary steps to ensure your room addition will meet all your HOA guidelines. In addition to our creative design ability, our expertise ranges from knowledge of Arizona building codes to appreciation and awareness of the different architectural styles that makeup Arizona homes.
