Love your neighborhood but need more space? An addition lets you grow your home without moving. Appena Properties, LLC is a family-owned general contractor based in Holliston, MA, run by Tarciso and Hellem. We help homeowners in Holliston and nearby MetroWest towns, including Framingham, Ashland, Hopkinton, Medway, Sherborn, and Milford, expand their space cost-effectively by designing and building new additions, dormers, and second levels.
We work closely with you through the whole construction process, starting with the initial planning phase. We listen to your ideas, plan every detail, and design an addition that fits your home, your lot, and your budget. Our goal is a modern, energy-efficient home suited to your unique needs.
Our services cover every phase of building an addition: a completed foundation for the structure's base, framing for structural integrity, foam insulation to help control indoor temperature and reduce energy use, blueboard hanging and wall plastering for interior walls and ceilings, vinyl siding installation outside, and flooring inside. You can see this work in our House Addition in Bellingham and Home Addition in Lincoln, MA projects.
Our clients appreciate the experience. One addition client wrote on BuildZoom that they were extremely happy with their finished addition and found the team very professional, easy to communicate with, and quick to answer questions. Throughout your project you'll get responsive, personalized service, honest communication, and a full construction materials and workmanship guarantee.

Frequently Asked Questions
Do I need a permit for a home addition in Massachusetts?
Yes. Additions need a building permit from your town's building department, and plumbing, electrical, and gas work need their own permits. Your project also has to meet local zoning rules such as setbacks, height, and lot coverage.
What types of additions does Appena build?
We design and build home additions, dormers, and second levels, and we also build new homes. We handle the work from foundation and framing through insulation, interior walls, siding, and flooring.
Should I build out or build up?
It depends on your lot size, your town's setback and height rules, your home's existing structure, and how you want to use the new space. A ground-level addition uses more of your yard. A second level or dormer adds room without taking up more lot. We'll look at your property with you and talk through the options.
Will my addition match my existing house?
That's one of our main goals. We plan the exterior lines, siding, windows, and interior finishes so the new space looks and feels like part of your home.
Can I live at home while my addition is built?
Many homeowners stay home during an addition, especially while most of the work is outside. There may be some disruption when the new space is connected to the existing house. We'll explain what to expect before we start.
