Dimensions 3D, LLC

Livia Givoni came to building from the corporate side. She says she worked as a senior executive and global project manager for a large multinational before going out on her own, and has now been a builder for more than 23 years. Her company, Dimensions 3D, has been an LLC in Natick since 2007 and takes on custom homes, additions and whole-house renovations, along with kitchens, bathrooms and landscape and hardscape work. Its Massachusetts home improvement contractor registration is active. The Better Business Bureau grades it A+, though the business is not BBB accredited. Givoni describes the company as woman-owned, and herself as one of only a few female licensed general contractors and builders in Massachusetts. It is a small shop — the BBB profile lists one employee, managed by Givoni — so on a custom build or a gut renovation, ask early how the trades are staffed and supervised and who is on site day to day. A homeowner who wants the builder herself running the job, rather than a project manager two steps removed, will find that shape here. Get the scope, schedule and payment milestones in writing, and confirm insurance before work starts.
