Addition for Watertown Homes
Building an addition in Greater Boston means designing for freeze-thaw swings moderated slightly by the coast, wind funnelled between buildings, and damp that lingers in shaded side yards. A new roof plane meeting an old one is exactly where ice and water find their way in, so on Watertown additions we detail that intersection first and everything else follows from it.
An addition is the most demanding thing a residential builder does: new foundation, new framing tied into old, roof lines that have to resolve honestly, and mechanicals extended from systems sized for a smaller house. We do all of it.
What Watertown Properties Actually Need
- The housing stock here
- Two-family houses at scale here share driveways and party-line setbacks, so a roof or siding job affects two households at once.
- Working on the site
- Shared driveways mean access is coordinated with the abutter before the first delivery.
- Permits and inspections
- The town enforces setback and street occupancy rules tightly given lot density.
What Goes Wrong in Greater Boston
The bolted-on look
Mismatched rooflines, siding that doesn’t align, and window proportions that give it away instantly from the curb.
Zoning discovered too late
Setbacks, lot coverage, and septic capacity kill more additions than budget does - and usually after money has been spent on design.
Leaks where old meets new
The junction between existing and added structure is the single most common failure point, and the hardest one to fix afterward.
