The highest long-term ROI of any addition.
Boston's most affordable alternative, with an older housing stock and a renovation market driven by first-time buyers improving at-purchase.

Worcester conditions
Building adu for Worcester conditions
Worcester's lot rules, setbacks, and parking requirements decide what's buildable before any design starts, so the firms we match confirm zoning feasibility on your specific parcel first. A small footprint loses heat fast, so in Worcester's coastal New England winters the envelope and mechanical sizing matter more per square foot than they would on the main house.
