The AWC Home Addition Process
Feasibility & Assessment
We assess your home, lot, and goals to confirm what's possible and what it will take.
Design & Engineering
We develop plans that tie cleanly into your existing structure and systems.
Permitting
We prepare and file permits and any zoning relief required for setbacks or lot coverage.
Construction
We sequence the build to protect occupied areas and keep the jobsite clean and safe.
Inspection & Handover
We coordinate final inspections and walk you through your finished, integrated space.
Frequently Asked Questions
Do I need a permit for a home addition in MA?
Yes — additions require building permits and may require zoning review for setbacks or lot coverage. We manage all of it.
How long does a home addition take?
Typically 3–8 months depending on scope, with second-story additions taking longer than single-room additions.
Will I be able to live in my home during construction?
Usually yes. We sequence the work and protect the occupied areas, and we'll set clear expectations up front.
How much does a home addition cost?
It depends on size, complexity, and finishes. We provide a clear, itemized estimate after assessing your home and goals.
